Cisco Secure Firewall 3100 Series UAE
A performance-focused firewall family for organisations that need to protect high-bandwidth Internet access, data-centre traffic, hybrid users and segmented enterprise networks without choosing a chassis only from headline throughput. The practical buying decision is the combination of inspected traffic, session growth, VPN load, port speed, software mode, licensing, management architecture and resilience.
For UAE procurement, quote accuracy depends on the exact model, software image, subscription term, management choice, network modules, transceivers, power redundancy and implementation scope.
Direct answer: what should a UAE buyer know first?
Why the Cisco Secure Firewall 3100 Series exists
The 3100 Series occupies the part of an enterprise security design where a firewall is expected to do considerably more than basic packet filtering. Modern perimeter and segmentation appliances may be asked to classify applications, enforce identity-aware policy, inspect traffic for intrusion activity, integrate threat intelligence, terminate VPNs, record events for investigation and preserve predictable user experience while doing those tasks. A platform that looks sufficient when measured only against raw Internet bandwidth can become undersized when security services, encrypted sessions and rapid connection creation are added. Cisco therefore differentiates the five 3100 models not just by nominal firewall throughput but also by inspected throughput, session scale, connection establishment rate, VPN capability and interface expansion.
For a UAE business, the family can make sense in a number of environments: a headquarters with multiple Internet links; a large branch with growing SaaS use; a data centre that needs internal segmentation; a service-delivery environment with many simultaneous connections; or a central VPN point serving distributed users and sites. These are different workloads. The same 10 Gbps ISP circuit can produce very different firewall requirements depending on packet size, connection churn, TLS use, application mix, logging level and which inspection services are active. The selection process therefore needs to model workload rather than simply match a WAN number to a brochure number.
The family also gives buyers a deliberate interface progression. The 3105, 3110 and 3120 provide eight 1G copper interfaces plus eight fixed 1/10G SFP-family interfaces, while the 3130 and 3140 move the fixed SFP interfaces to 1/10/25G capability. All models provide a network-module slot, but the usable high-speed module options differ by model and software support. This distinction matters when the firewall sits between 25G server or core links, when a design uses breakout cabling, or when the organisation expects to move from 10G to faster uplinks during the appliance life.
A sensible purchase therefore starts with architecture. Determine where the appliance will sit, what traffic crosses it, which security controls must remain enabled at peak load, how failure is handled and what interfaces the surrounding switches, routers, carriers and servers actually use. Once those points are known, the 3100 Series becomes straightforward to compare because each higher model provides additional performance and, at the upper end, more high-speed I/O flexibility.
FTD performance comparison across all five models
The figures below are Cisco data-sheet test values for Firewall Threat Defense. They are useful for relative model comparison, not a promise that every production network will reproduce the same result. Cisco explicitly notes that performance varies with enabled features, packet size, traffic protocol mix and software release. Real sizing should include operational headroom.
| FTD metric | 3105 | 3110 | 3120 | 3130 | 3140 |
|---|---|---|---|---|---|
| FW + AVC throughput | 10 Gbps | 17 Gbps | 21 Gbps | 38 Gbps | 45 Gbps |
| FW + AVC + IPS throughput | 10 Gbps | 17 Gbps | 21 Gbps | 38 Gbps | 45 Gbps |
| Maximum concurrent sessions with AVC | 1.5 million | 2 million | 4 million | 6 million | 10 million |
| Maximum new connections/second with AVC | 90,000 | 130,000 | 170,000 | 240,000 | 300,000 |
| TLS test throughput | 3.2 Gbps | 4.8 Gbps | 6.7 Gbps | 9.1 Gbps | 11.5 Gbps |
| IPsec VPN throughput, Cisco baseline test | 5.5 Gbps | 8 Gbps | 10 Gbps | 17.8 Gbps | 22.4 Gbps |
The TLS row is especially important for environments that decrypt or otherwise process substantial encrypted traffic. Cisco’s published test uses a defined TLS profile, so it should be treated as a reference point rather than converted directly into an expected production ceiling. A design with small packets, many short-lived sessions, multiple security services, heavy logging or large remote-access demand should preserve more headroom than a stable, large-packet site-to-site workload.
Choosing between 3105, 3110, 3120, 3130 and 3140
The family is easiest to understand as five capacity steps rather than five interchangeable boxes. The right model is the one that satisfies the most demanding realistic workload with enough operational margin, while also meeting interface and high-availability requirements. The model cards below focus on the purchasing implication of each step.
Cisco Secure Firewall 3105
The 3105 is the entry point to the family and is designed for enterprise branch environments that may need room to grow. Cisco publishes 10 Gbps for FW+AVC+IPS, 1.5 million concurrent sessions with AVC and 90,000 new connections per second with AVC. Its fixed I/O combines eight 1G RJ-45 ports with eight 1/10G SFP-family ports.
Its most important architectural limitation within the family is clustering: Cisco states that 3100 Series clustering is available on the other models but not on the 3105. That does not make the model unsuitable for resilient design, but it means a buyer whose scale plan specifically depends on multi-chassis clustering should start comparison at the 3110. The 3105 is strongest when 10G-class inspected capacity, standard 1/10G interfaces and branch-scale session demand provide sufficient headroom.
Cisco Secure Firewall 3110
The 3110 increases FTD FW+AVC+IPS throughput to 17 Gbps and the Cisco data sheet lists 2 million concurrent sessions with AVC plus 130,000 new connections per second. It retains the eight 1G copper and eight 1/10G SFP-family fixed ports, so its main advantage over the 3105 is performance and scale rather than a new fixed-port class.
This model often deserves attention when an organisation wants the clustering path available to the 3110–3140 range, expects more VPN or inspected traffic than the 3105 can comfortably absorb, yet does not require the 25G fixed-port capability of the 3130 or 3140. For procurement, compare the 3110 against the 3120 using projected three-to-five-year growth, not only the current average, because the cost of changing a firewall later can exceed the value of buying modest headroom at the start.
Cisco Secure Firewall 3120
The 3120 is the highest model in the family before the fixed-interface design moves to 25G capability. Cisco lists 21 Gbps FW+AVC+IPS, 4 million concurrent sessions with AVC and 170,000 new connections per second with AVC. Its baseline IPsec VPN figure in the FTD data sheet is 10 Gbps.
The model is attractive for buyers that need more session and inspection headroom than the 3110 but can still build the physical topology around 1G copper and 1/10G SFP-family fixed interfaces plus supported expansion. It can be a balanced choice for a busy headquarters, sizeable Internet edge or segmentation role where 25G server or core adjacency is not yet required. If 25G is already on the network roadmap, evaluate the 3130 rather than assuming adapters or later cabling changes will solve the interface mismatch cleanly.
Cisco Secure Firewall 3130
The 3130 is a substantial step in both performance and high-speed I/O. Cisco publishes 38 Gbps FW+AVC+IPS, 6 million concurrent sessions with AVC and 240,000 new connections per second. Its eight fixed SFP-family network ports support 1/10/25G, giving it a natural fit beside modern 25G aggregation and server infrastructure.
The 3130 also supports high-speed network-module choices that the 3105, 3110 and 3120 do not recognise in software, including Cisco’s 4-port 40G and 2-port 100G options, subject to software-release and transceiver compatibility. This matters for data-centre or campus-core designs where interface speed can be a hard requirement independent of security throughput. A 100G physical interface does not mean the firewall can inspect 100 Gbps of arbitrary traffic; interface capacity and security-processing capacity are separate sizing dimensions.
Cisco Secure Firewall 3140
The 3140 is the highest-performance appliance in the 3100 family. Cisco lists 45 Gbps FW+AVC+IPS, 10 million concurrent sessions with AVC, 300,000 new connections per second and a 22.4 Gbps baseline FTD IPsec VPN test figure. Like the 3130, it provides eight fixed 1/10/25G SFP-family interfaces and access to the higher-speed expansion class.
Choose the 3140 when the additional inspection, session, VPN or growth margin is justified by the workload, not simply because it is the largest model. It can be appropriate for demanding headquarters, high-volume Internet edge, large segmentation zones or consolidated security designs. Conversely, if measured peak demand fits comfortably within a 3130 after realistic services and headroom are applied, the 3130 may be the more disciplined choice. The purchasing goal is a supportable architecture, not maximum specification for its own sake.
Hardware, rack, management and interface fundamentals
All five Cisco Secure Firewall 3100 models use a 1RU chassis measuring approximately 1.75 x 17 x 20 inches (4.4 x 43.3 x 50.8 cm). That makes the family physically compact, but rack planning still needs to account for front-to-rear airflow, cable bend radius, power feeds, service access and the depth of surrounding equipment. Cisco’s current hardware installation guide describes front-to-rear airflow from the I/O side toward the non-I/O side, which should align with the data-centre cold-aisle/hot-aisle plan rather than being treated as a cosmetic detail.
| Hardware item | 3105 / 3110 / 3120 | 3130 / 3140 |
|---|---|---|
| Form factor | 1RU | 1RU |
| Fixed copper data ports | 8 x 10/100/1000BASE-T RJ-45 | 8 x 10/100/1000BASE-T RJ-45 |
| Fixed fibre/DAC-capable data ports | 8 x 1/10G SFP-family | 8 x 1/10/25G SFP-family |
| Dedicated management | 1 x 1/10G SFP management port | 1 x 1/10G SFP management port |
| Console and USB | RJ-45 serial console plus USB Type-A | RJ-45 serial console plus USB Type-A |
| High-speed expansion emphasis | 1/10G-class expansion options; verify exact module/software compatibility | 1/10/25G, 40G and supported 40/100G module choices; verify exact software and optics |
The integrated management port deserves attention during design. Cisco documents it as a 1/10G SFP-based interface, so a buyer should not assume the management connection is ordinary copper RJ-45. If the management network is copper-only, the compatible transceiver or alternative cabling approach must be identified before installation. The same applies to the fixed SFP-family data ports: the chassis can provide the port cage, but the optics, DAC or other supported media must match distance, fibre type, connector, switch port and software compatibility.
Storage, fan modules and power components are also serviceability considerations. Cisco publishes a 900 GB storage device with a spare slot, two hot-swappable fan modules, and 400W power-supply options. The 3105, 3110 and 3120 can be ordered with a single AC supply with an optional second supply, while the 3130 and 3140 are documented with dual AC supplies in the data sheet; DC variants are also documented. A resilient firewall pair connected to one power circuit is not a resilient service, so the power design should distribute redundant supplies and, where practical, redundant appliances across independent PDUs or UPS-backed feeds.
Network modules: where interface planning can change the model decision
The NM-2 expansion slot is one of the reasons the 3100 Series can fit a wide range of topologies, but the module must be selected as part of the architecture rather than added as an afterthought. Cisco’s hardware documentation includes 1/10G, 1/10/25G, 40G, 40/100G and hardware-bypass module families. Not every module is supported on every chassis. In particular, Cisco states that the 8-port 1/10/25G, 4-port 40G and 2-port 100G modules are supported on the 3130 and 3140, while the software on 3105, 3110 and 3120 does not recognise those higher-speed modules even if one can physically be inserted.
For the 3130 and 3140, the 2-port 100G module is a useful example of why physical port speed must not be confused with firewall inspection throughput. Cisco documents the module as two QSFP/QSFP28 ports supporting 40/100G operation, with breakout capability into multiple 10G or 25G interfaces using supported cables. This can solve an adjacency or cabling requirement at a modern core or data-centre fabric, but the appliance’s published security-processing limits remain the values for the chosen 3130 or 3140. A 100G uplink may carry traffic whose average inspected load is much lower, may be used for aggregated connectivity, or may be part of a design where not all theoretical link capacity is expected to traverse the firewall simultaneously.
Software release is another dependency. Cisco’s current compatibility information ties high-speed modules and specific transceivers to minimum FTD or ASA releases, and newer releases add support for additional optics. Therefore the bill of materials should never list only “100G module” or “25G SFP” without also checking the firewall software version and Cisco’s supported transceiver matrix. This is particularly important during migration, where the target software release may be constrained by policy features, management compatibility or upgrade sequencing.
Procurement rule for optics and modules
Specify the port speed, media type, fibre standard, distance, connector, peer-device port type, breakout requirement and software release before ordering transceivers or network modules. This avoids a common failure mode in which the firewall chassis is correct but the installation is delayed by unsupported optics, missing DACs, incompatible breakout cables or a module that the selected chassis/software combination cannot use.
FTD or ASA: choose the software mode before the hardware quote is final
Each model in the Cisco Secure Firewall 3100 Series can run either Firewall Threat Defense or ASA software. That choice affects the security feature set, policy model, management workflow, migration method, licensing and often the operational team’s day-to-day experience. It should therefore be made before a final bill of materials is approved. Buying the chassis first and deciding the operating model later can create avoidable reimaging, licence, management and migration work.
Firewall Threat Defense (FTD) is the normal path when the project requires Cisco’s integrated next-generation firewall functions such as application visibility and control, intrusion prevention, security intelligence, malware-related controls and URL filtering according to the selected entitlements. FTD can be managed locally in appropriate designs or centrally through Cisco management platforms. Cisco’s 2026 getting-started material covers Firewall Device Manager, on-premises or centrally located Firewall Management Center workflows, and cloud-delivered management approaches. The right management model depends on how many appliances are being administered, how policies are shared, where logs must reside, how change control works and whether the organisation has an established Cisco security management environment.
ASA software remains relevant where the requirement is aligned with ASA capabilities, existing operational practice or a migration architecture that specifically depends on ASA behaviour. Cisco publishes separate ASA performance figures for the 3100 family, and the appliances support familiar high-availability functions. However, a project should not assume that every FTD feature, licence or management method maps one-for-one to ASA. The software image is a foundational design decision, not a cosmetic interface preference.
If the organisation is moving from older ASA hardware to a 3100 appliance, the team should identify which policies can be carried forward, which configurations require redesign, how NAT and VPN settings will be validated, whether central management will change, and how the cutover will be tested. If the organisation is moving from an existing FTD platform, the questions shift toward management compatibility, policy deployment, object cleanup, feature parity, software-release sequencing and event continuity. In either case, a clean migration design is usually more valuable than attempting to preserve every legacy object simply because it already exists.
Licensing and subscriptions: budget for the security outcome, not only the chassis
A Cisco Secure Firewall 3100 quotation is incomplete if it contains only the appliance. Cisco licensing determines which security functions are available, how they are managed and, for subscriptions, the term over which the entitlement remains active. Current Cisco getting-started documentation for the 3100 family shows a required base entitlement and lists additional capabilities such as IPS, Malware Defense, URL Filtering, Cisco Secure Client and carrier-oriented functions. Cisco’s terminology can vary by management path and software generation, so the exact current entitlement name and PID should be checked in the ordering workflow rather than copied from an old quote.
For a typical enterprise NGFW project, the key question is what the policy must actually do. If intrusion prevention is part of the security design, the quotation must include the necessary IPS entitlement. If the organisation wants malware-related protection or URL-category enforcement, those functions need the corresponding licences or subscription bundle. Remote-access VPN projects may also require Cisco Secure Client licensing depending on user count and feature set. A buyer should map each required security control to an entitlement and term, rather than choosing a bundle because its name sounds comprehensive.
Subscription duration affects both commercial planning and operational continuity. One-, three- and five-year terms are common in Cisco ordering structures for security subscriptions, but the exact available term and bundle should be confirmed at quote time. Longer terms may simplify renewal administration, while shorter terms can fit projects with uncertain lifecycle or budget horizons. The important point is to align the licence end date with the organisation’s refresh and renewal process so that security services do not lapse unnoticed.
Management can introduce additional dependencies. If the appliance will register to a Firewall Management Center or cloud-delivered management service, confirm the management platform version, capacity, tenancy and licensing model as part of the same design. A firewall that has the correct threat subscription but cannot be integrated into the intended management architecture is not deployment-ready. FourTeck’s quotation input should therefore include the preferred management approach, existing Cisco accounts or management platforms, the number of devices being controlled and the required subscription term.
VPN, TLS and encrypted-traffic sizing
Encrypted traffic is one of the most common reasons a firewall performs differently in production from what a simple “firewall throughput” number suggests. The 3100 Series data sheet therefore publishes separate TLS and IPsec VPN values. For FTD, Cisco lists TLS test throughput from 3.2 Gbps on the 3105 up to 11.5 Gbps on the 3140, using a defined TLS 1.2 test profile. Baseline FTD IPsec VPN test values range from 5.5 Gbps on the 3105 to 22.4 Gbps on the 3140. These figures help compare models, but the exact deployment may differ because cipher choice, packet size, tunnel type, connection count, software release and other enabled services all influence the result.
For site-to-site VPN, document the number of tunnels, expected aggregate encrypted throughput, peak utilisation, routing design, failover behaviour and cryptographic standards. A design with a handful of stable high-bandwidth tunnels is different from one with hundreds or thousands of dynamic peers. If the 3100 is a central hub for branches, failure testing also matters: when a secondary WAN path or firewall takes over, the surviving unit may suddenly receive the entire tunnel load. Capacity planning should include that failure state rather than only normal steady-state distribution.
For remote access, user count alone is not enough. Estimate simultaneous users, average and peak traffic per user, split-tunnel or full-tunnel policy, voice/video use, large software downloads, SaaS traffic and authentication dependencies. A workforce of 5,000 registered users may have far fewer concurrent sessions than that, while a smaller engineering population can generate much heavier per-user traffic. The requirement should describe concurrency and traffic behaviour so the firewall and Secure Client entitlements can be sized together.
TLS inspection deserves separate treatment. If the security policy decrypts a significant portion of outbound or inbound traffic, measure how much of the traffic is eligible for decryption, identify applications that must bypass decryption for privacy or technical reasons, and allow capacity for certificate operations and security inspection after decryption. The published TLS number is not interchangeable with the FW+AVC+IPS number. Choosing a model from the larger of several relevant workloads is more reliable than using one throughput metric as a universal capacity figure.
High availability, clustering and resilience design
Cisco lists active/active and active/standby high availability for the Secure Firewall 3100 family, and the data sheet states that clustering can scale to as many as eight chassis on the 3110, 3120, 3130 and 3140. The 3105 does not support clustering. These capabilities are valuable, but resilience is a system property: two appliances are only one part of the design. The upstream and downstream switches, routing protocols, power supplies, management network, carrier links and physical cabling must also avoid unnecessary single points of failure.
An active/standby pair is often appropriate where predictable failover and operational simplicity are priorities. Capacity should be calculated so that one appliance can carry the required traffic during a failure or maintenance event. If each node normally runs at a level that already approaches its safe production ceiling, failover can turn a hardware failure into a performance incident. This is why utilisation headroom is a resilience requirement, not only a performance preference.
Clustering can provide additional scale and architectural flexibility on supported models, but it introduces its own design requirements, software constraints and operational procedures. Buyers should confirm that the intended FTD or ASA version supports the desired cluster design, that surrounding networking can provide the necessary connectivity, and that the team understands how upgrades, failures and state are handled. Clustering should be chosen because the architecture needs it, not simply because the platform offers it.
Power redundancy should be designed to the same standard. Cisco documents 1+1 redundancy when dual supplies are present. Connect those supplies to independent power paths where the site infrastructure permits. For a two-firewall HA pair, spreading appliances across rack power domains and switch paths can protect against a failure that would defeat both devices at once. The final bill of materials should therefore show not only appliance quantity but also the intended power-supply count, rack location, PDU feeds and peer-network connections.
Six practical deployment patterns
1. Enterprise Internet edge
At the Internet edge, the firewall may inspect north-south web, SaaS, email, cloud and application traffic while enforcing NAT, threat controls and VPN services. Size to measured peak Internet traffic plus expected circuit growth, then model the performance impact of IPS, application control and TLS inspection. If multiple carriers are used, consider the failure case in which one link or one firewall carries the combined load. Interface selection should match carrier handoffs and core-switch speeds without relying on unnecessary media conversion.
2. Data-centre segmentation
A segmentation firewall can see traffic volumes that have little relationship to Internet bandwidth because application tiers, virtualisation clusters, backup systems and internal services communicate east-west. Here, session scale and interface speed can be as important as raw inspected throughput. The 3130 and 3140 become especially relevant when 25G, 40G or supported 100G physical connectivity is part of the topology. Define which zones truly require inspection and avoid forcing unrelated traffic through a bottleneck without a security reason.
3. Headquarters with hybrid users
A headquarters appliance may combine Internet security, site-to-site VPN, remote access and application-policy enforcement. That consolidation simplifies architecture but also combines several loads on one platform. Estimate remote-access concurrency, peak office traffic, branch VPN traffic and inspection overhead together. A model that is comfortably sized for office Internet traffic alone may be too small once thousands of encrypted users are added. The operational plan should also include authentication, certificate, DNS and identity dependencies because user access can fail even when the firewall hardware is healthy.
4. Large branch or regional hub
The 3105 and 3110 can be attractive for branches or regional hubs that have outgrown entry firewalls but do not need upper-end data-centre interfaces. The decision should reflect growth in SD-WAN or WAN traffic, local Internet breakout, branch-to-cloud use, user count and the possibility that a regional site becomes a temporary hub during another site failure. If clustering is an explicit roadmap requirement, remember that the 3105 does not support it, which can move the shortlist to the 3110 even when current throughput would otherwise fit the 3105.
5. High-volume VPN headend
A VPN headend should be sized from encrypted throughput, tunnel or user concurrency, failover behaviour and cryptographic requirements. The 3130 and 3140 provide materially higher baseline FTD IPsec test values than the lower models, but the correct choice still depends on the actual VPN design. Full-tunnel remote access can drive much more firewall traffic than split tunnelling. Site-to-site tunnels can create bursts during replication or backup windows. Capture these peaks so the appliance does not become the limiting factor during exactly the period when connectivity matters most.
6. Consolidated multi-zone security
Some organisations use one firewall pair to enforce policy between Internet, DMZ, user, server, partner and management zones. This can reduce appliance count and centralise policy, but it raises the importance of interface count, VLAN design, routing, session scale and change control. The 3100 family can expose many interfaces through fixed ports and a network module, yet logical segmentation should remain understandable. If a single policy domain becomes too complex, separate security domains or additional appliances may be easier to operate even when one large model has enough raw capacity.
Installation planning for UAE offices and data centres
The physical installation is straightforward only when the rack, airflow, power, optics and management path have been planned in advance. Cisco specifies the 3100 chassis for a standard 19-inch rack and recommends slide rails in its hardware guidance. Confirm the rack has sufficient depth and front/rear clearance, especially where cable managers, high-density optics or deep neighbouring equipment can restrict access. The appliance should not be squeezed into a rack position that prevents fan or power-supply service.
Airflow is front to rear, from the I/O side toward the non-I/O side. In a professionally managed facility, place the device so this direction matches the cold-aisle/hot-aisle arrangement. Cisco lists an operating range up to 40°C in the published hardware specifications, but a good data-centre design should not plan routine operation near the maximum. Local hot spots, blocked intake, failed CRAC capacity or dense adjacent equipment can raise inlet temperature unexpectedly. Environmental monitoring and clean airflow preserve margin just as traffic headroom does.
Power design should identify AC or DC requirements, plug type, PDU capacity and redundancy before equipment arrives. Cisco documents 100–240V AC operation for the AC supplies and supports redundant power when dual supplies are fitted. For HA pairs, use independent electrical paths where available. If the site has only one UPS or one PDU, the project should explicitly record that limitation rather than assume dual supplies create full power resilience.
Cabling is another common source of delay. The fixed SFP-family data interfaces and SFP-based management port require compatible transceivers, DACs or other supported media. Determine whether each link is copper, multimode fibre, single-mode fibre, direct attach or breakout; document the link distance and peer port; and select the optics accordingly. For 3130/3140 high-speed modules, verify not just connector type but also the firewall software release because Cisco adds transceiver support over time.
Finally, plan an out-of-band or console-access method for the initial build and recovery. Cisco provides an RJ-45 serial console and USB port, while the management interface can be used for administration depending on the software workflow. The installation runbook should state how a technician reaches the appliance if production routing is unavailable. That small detail can save significant time during first boot, reimaging, recovery or a remote maintenance event.
Migration planning: replacing a firewall without importing old problems
A firewall refresh is often treated as a hardware replacement, but the most valuable part of the project is usually the policy and architecture review that happens around it. Before moving to a Cisco Secure Firewall 3100, inventory interfaces, VLANs, routes, NAT rules, VPNs, access policies, security objects, identity dependencies, certificates, logging destinations, monitoring integrations and administrative workflows. Mark which items are still required. Years of incremental change can leave unused objects, obsolete rules and workarounds that should not be migrated merely because they are present on the old platform.
If the source is an ASA environment and the destination will run FTD, treat the project as a platform transition rather than a simple configuration copy. Identify feature differences, management changes and any policy constructs that require redesign. Test critical NAT, site-to-site VPN, remote-access, routing and application flows in a controlled sequence. A migration tool or converted configuration can accelerate the process, but the output still needs technical review. The target should be a validated policy set, not a perfect textual replica of the old configuration.
If the source already runs FTD, the migration may be more direct, but software and management compatibility still matter. Confirm the target 3100 model supports the intended software release, verify the Firewall Management Center or cloud-management version, and plan how device registration, policy deployment and licensing will occur. If a high-speed network module is required, its software minimum may influence the upgrade sequence. This is especially important for 3130/3140 deployments using newer 100G module or optic support.
Build a rollback plan before the cutover. Define the exact conditions that trigger rollback, preserve the old device configuration, maintain physical access to the previous links where practical and allocate enough change-window time for verification rather than only cable movement. Test DNS, DHCP-related flows where applicable, identity, application access, inbound publishing, outbound NAT, VPN, monitoring, logging, routing convergence and HA state. A cutover that passes ping tests but silently loses security telemetry is not complete.
For large environments, move in logical stages. The team can validate management and licensing first, then base routing and interfaces, then security policy, then VPN or advanced functions. When a big-bang migration is unavoidable, pre-stage as much as possible and create a short validation checklist that network, security and application owners can execute in parallel. Operational ownership should also be clear: the team that manages Cisco policy after go-live needs access, documentation, backup procedures and a defined escalation route.
A 3100 refresh is also a good point to reconsider interface design. If the old firewall used many 1G links because that was the historical constraint, a new 3130 or 3140 may allow cleaner 10G or 25G aggregation. Conversely, there is no benefit in forcing 25G interfaces into a topology that remains 1G everywhere else. The migration should simplify where possible, preserve compatibility where necessary and avoid adding complexity just because the new chassis offers more options.
Management, logging and day-two operations
The long-term cost of a firewall is shaped by how efficiently it can be operated. Decide whether the 3100 will be managed locally or through a central Cisco platform, and design the management network before deployment. Central management is generally easier to justify when multiple firewalls share policy standards, when audit evidence must be produced consistently, or when a security team needs consolidated event visibility. Local management can suit smaller or deliberately independent deployments, but the organisation still needs backup, role-based access and change-control procedures.
Logging should be sized and routed deliberately. Security events, connection records, intrusion alerts and system messages can create substantial data volume. Decide what must be retained, for how long, and where it will be analysed. If logs feed a SIEM, confirm network reachability, time synchronisation and event parsing before go-live. Excessive logging of low-value traffic can increase operational noise, while too little logging can make investigations difficult. The goal is actionable evidence aligned with the organisation’s incident-response and compliance requirements.
Software maintenance is another operational dependency. Cisco releases add features, fixes, module support and transceiver compatibility, but upgrades should follow a tested lifecycle rather than be applied ad hoc. Maintain a supported release plan, read release notes, check management-platform compatibility, confirm module and VPN dependencies, back up configuration, and schedule maintenance with a rollback path. In an HA environment, understand the upgrade procedure and expected traffic impact before beginning.
Performance monitoring should compare actual production behaviour with the sizing assumptions made during procurement. Track interface utilisation, connection counts, CPU and memory trends, VPN load, event-processing behaviour and growth over time. If the appliance was purchased with healthy headroom, monitoring tells the team when that reserve is being consumed. This turns future expansion into a planned decision instead of an emergency replacement triggered by user complaints.
Common sizing mistakes to avoid
Using ISP speed as the only input
A 10 Gbps circuit does not automatically mean a 10 Gbps inspected firewall is sufficient. Security services, encrypted traffic, east-west flows, VPN and growth can make the real requirement higher. Use measured peaks and the actual policy stack.
Ignoring connection rate
Some applications create large numbers of short-lived sessions without consuming extreme bandwidth. Compare concurrent-session and new-connection-per-second requirements, especially for busy public services, SaaS-heavy networks and high-transaction environments.
Confusing link speed with inspection speed
A 40G or 100G network module solves interface connectivity; it does not raise the appliance’s security-processing specification to the same number. Size physical topology and inspection workload as two related but separate dimensions.
Forgetting the failure state
An HA pair must survive with one node carrying the required service. If normal utilisation already consumes most of one appliance’s safe capacity, failover may protect availability only to introduce congestion. Include N+1 or failover headroom.
Leaving optics until installation day
SFP, SFP+, SFP28 and QSFP-family links depend on speed, fibre type, distance, peer port and software compatibility. The chassis alone is not a complete cabling solution. Add each required optic, DAC or breakout item to the bill of materials.
Quoting subscriptions after the hardware
If IPS, malware, URL filtering or remote-access capabilities are required, licensing belongs in the original design. Treating subscriptions as an optional later purchase can produce a firewall that powers on but does not deliver the intended security policy.
UAE procurement and quotation guidance
For a UAE quotation, the model name is only the beginning. A complete request should state whether the project needs one appliance or an HA pair, which software mode is required, the security subscriptions and term, the management architecture, interface and network-module choices, optics or DACs, power-supply redundancy, rack accessories, support coverage and implementation services. If any of those points are unknown, provide the underlying requirement instead—for example, “two 25G links to the core over multimode fibre” or “3,000 concurrent remote users with full-tunnel Internet traffic”—so the bill of materials can be designed rather than guessed.
Availability and lead time can vary by exact chassis PID, power option, network module, transceiver and subscription bundle. Do not treat a general statement that “3100 Series is available” as confirmation that the exact combination is immediately deliverable. For time-sensitive projects, ask for a quote tied to the required configuration and deployment date. If the project depends on a specific software release for high-speed module support, record that requirement as well.
Support should be aligned with business impact. A firewall protecting a small secondary site may tolerate a different response model from a pair at the core of a revenue-generating service. Consider the desired replacement response, software support, access to Cisco technical resources and internal escalation capability. The support term should also align with the expected product lifecycle and subscription renewal schedule so that hardware and software coverage are not managed as unrelated dates.
For deployment, clarify whether the scope is supply-only, rack-and-stack, base configuration, full policy migration, VPN migration, HA build, management integration, testing or ongoing support. These are materially different services. A clean scope prevents the commercial quote from hiding assumptions about who will configure routing, migrate certificates, validate applications, coordinate change windows or provide post-cutover support.
UAE buyers who want broader infrastructure coordination can review FourTeck UAE for regional technology services. Where the firewall project includes network, server, endpoint or operational support dependencies, defining the surrounding scope early usually produces a more accurate deployment plan than treating security as an isolated appliance purchase.
When a 3100 Series appliance may not be the right answer
The Cisco Secure Firewall 3100 Series is capable, but it should not be selected automatically for every firewall project. A smaller environment may not need multi-gigabit inspected capacity, millions of sessions or high-speed expansion. In that case, a smaller platform can reduce acquisition and support cost while still meeting the requirement. The right comparison is based on workload, features and growth rather than the prestige of a higher product family.
At the other extreme, a project may exceed what the 3140 can comfortably deliver once inspection, TLS, VPN, session scale and failure-state headroom are combined. Very high-throughput data-centre or service-provider designs should compare larger Cisco firewall platforms or a distributed architecture rather than forcing the biggest 3100 into a role beyond its practical capacity. The 100G interface option on the 3130/3140 should not be mistaken for 100G of full security inspection.
A 3100 may also be the wrong operational choice if the organisation is standardised on a different security platform and has no business reason to change. Migration cost includes policy conversion, training, management, integration, runbooks and incident-response procedures. Hardware features should be considered alongside that operational cost. Conversely, an established Cisco security environment can make management integration and skills alignment significant positives.
Within the family, do not overbuy solely for port speed if a simpler topology works, and do not underbuy because today’s average utilisation is low. A balanced shortlist normally compares at least two neighbouring 3100 models and explains the trigger for moving up: additional inspected throughput, session scale, VPN demand, 25/40/100G connectivity, clustering requirement or growth margin. That makes the decision transparent and easier to defend during budget review.
Buyer FAQ: Cisco Secure Firewall 3100 Series UAE
How many models are in the 3100 Series?
Five: 3105, 3110, 3120, 3130 and 3140. They share the 1RU form factor but differ substantially in inspected throughput, session capacity, connection rate and high-speed interface options. Treat the series as a performance ladder rather than one product sold under five names.
Can the 3100 Series run ASA software?
Yes. Cisco states that each model can run ASA or Firewall Threat Defense. The choice should be made from feature, management, migration and operational requirements. Performance figures and some management capabilities differ between the two software paths, so do not mix FTD and ASA specifications in the same sizing calculation.
Which model supports 25G fixed interfaces?
The 3130 and 3140 have eight fixed 1/10/25G SFP-family data interfaces. The 3105, 3110 and 3120 have eight fixed 1/10G SFP-family data interfaces. If 25G adjacency is a hard design requirement, that difference can determine the model family position before throughput is considered.
Can the 3130 or 3140 use 100G ports?
Cisco’s current hardware documentation lists a 2-port 40/100G QSFP/QSFP28 network module for the 3130 and 3140. Software release and transceiver support must be checked for the intended configuration. The lower three models do not support that module in software.
Does a 100G module mean 100 Gbps firewall inspection?
No. Physical interface speed and security-processing throughput are different specifications. Cisco publishes 38 Gbps FW+AVC+IPS for the 3130 and 45 Gbps for the 3140 in the FTD data sheet. The high-speed module solves connectivity and aggregation requirements; it does not change those appliance processing values into 100 Gbps.
Does the 3105 support clustering?
No. Cisco’s data sheet states that clustering is available on the 3110, 3120, 3130 and 3140, up to eight chassis, while the 3105 is excluded. If a future scale-out cluster is part of the architecture, this is a decisive reason to compare the 3110 or higher even when current throughput would fit the 3105.
What throughput number should I use for sizing?
Use the metric that matches the enabled security services and traffic type, then add realistic headroom. For an FTD design using application control and IPS, the FW+AVC+IPS figure is more relevant than a plain firewall value. For heavy VPN or TLS inspection, the separate encrypted-traffic figures must also be evaluated.
Are SFPs and QSFPs automatically included?
Do not assume so. Treat optics, DACs and breakout cables as explicit bill-of-material items. Their selection depends on port speed, fibre type, link distance, peer equipment and Cisco compatibility. The management port is also SFP-based, so management cabling should be planned deliberately.
What licences should be included?
Include the required base entitlement and the subscriptions that map to the security policy, such as IPS, Malware Defense, URL Filtering and Cisco Secure Client where needed. Cisco licence naming and PIDs can evolve, so the exact current bundle and term should be validated when the quote is prepared.
Can FourTeck supply installation and migration support?
The quotation can be scoped for supply only or can include activities such as rack-and-stack, base configuration, policy migration, VPN migration, HA build, management integration, validation and post-cutover support. The exact scope should be stated so responsibilities and change-window work are clear.
How much growth headroom should I keep?
There is no universal percentage because traffic patterns differ. The design should include measured peak load, forecast growth, failure-state load and the effect of enabled security services. Preserve enough margin that normal software changes, user growth or a failed peer do not immediately push the remaining appliance to its practical limit.
What information speeds up a UAE quote?
Provide the preferred model if known, quantity, FTD or ASA choice, current and projected traffic, VPN users or tunnels, security services, management method, interface speeds, optics and distances, HA requirement, subscription term, support level and migration scope. If the model is unknown, these same inputs allow it to be recommended.
A practical model-selection workflow
Step 1: define traffic boundaries. Identify every significant path expected to cross the firewall: Internet, WAN, site-to-site VPN, remote access, DMZ, data-centre zones and internal segmentation. Use monitoring data where available. Record average and peak throughput, but also identify burst periods such as backups, software distribution, month-end processes or major video events.
Step 2: define the security stack. List the functions that must be enabled in steady state—application control, IPS, URL controls, malware-related services, TLS inspection, VPN and logging. Sizing from a plain stateful-firewall figure while planning to enable multiple NGFW services can produce an unrealistic result. Where Cisco publishes a metric matching the intended stack, use that as the comparison baseline.
Step 3: examine session behaviour. Estimate concurrent sessions and new connections per second. High-volume public services, microservices, SaaS-heavy networks and large user populations can generate substantial session churn even when bandwidth is moderate. Compare these requirements against the model’s published session values, then leave operational margin.
Step 4: size encrypted traffic independently. Quantify site-to-site VPN, remote-access traffic and TLS inspection. For remote access, use concurrent users and realistic per-user behaviour rather than the number of employees in the directory. For TLS, identify how much traffic will actually be decrypted and what applications or legal/privacy policies require bypass.
Step 5: solve the physical topology. Count required copper, 10G, 25G, 40G and 100G adjacencies. Identify the media and distance for each. If the design requires fixed 25G or supported 40/100G expansion, the 3130 or 3140 becomes the natural comparison set. If all adjacencies are 1G/10G, the 3105–3120 may remain viable depending on capacity.
Step 6: design the failure state. Decide whether the project uses a standalone appliance, HA pair or supported cluster. Calculate how traffic behaves after a node, carrier or path fails. The surviving design must still provide acceptable throughput and session capacity. Record power and switch redundancy at the same time.
Step 7: choose software, management and licences. Confirm FTD or ASA, the management platform, required threat subscriptions, Secure Client needs and support term. These items can affect migration and recurring cost, so they belong in the model decision rather than after it.
Step 8: compare neighbouring models. The final shortlist should usually show why the lower model was rejected or accepted and what the next model adds. For example, 3120 versus 3130 may turn on 25G interface need as much as throughput; 3105 versus 3110 may turn on clustering roadmap and growth. A transparent comparison creates a defensible purchasing decision and reduces the chance of a premature refresh.
Regional support and related FourTeck resources
For firewall-specific product, deployment and support discussions in Dubai and the wider UAE, Firewall Dubai by FourTeck is the most directly relevant specialist resource for this page. A 3100 project frequently touches broader infrastructure, so it is useful to define adjacent requirements rather than discover them during installation.
If the project includes network operations, endpoint support, systems administration or a wider managed-services requirement, review FourTeck IT Services UAE. For regional company information and UAE technology services, FourTeck UAE provides the local company view. Organisations coordinating projects across additional markets can also refer to FourTeck for the broader group presence.
These links are intended as practical navigation rather than a substitute for a scoped quotation. The firewall bill of materials should still be driven by the exact 3100 model, licences, ports, optics, resilience design and services required at the target UAE site.
Decision recap: the six choices that determine a successful 3100 deployment
What FourTeck needs from the buyer for an accurate quotation
You do not need to know every Cisco part number. Provide the business and technical requirement, and the bill of materials can be built from it. The most useful inputs are:
Preferred 3100 model if known; otherwise current peak traffic, expected growth and enabled security services.
Standalone, active/standby, active/active or cluster requirement, plus intended failure-state load.
Target software mode, current platform and desired software release if the project has a compatibility constraint.
Port counts and speeds, copper/fibre/DAC requirement, link distance, peer equipment and any 25/40/100G module need.
Site-to-site tunnel count, aggregate VPN traffic, remote-access concurrency and split/full-tunnel policy.
IPS, malware, URL filtering, Secure Client and any other required functions, plus preferred subscription term.
Local management, existing Firewall Management Center, cloud-delivered management or a new management requirement.
UAE site, rack environment, AC/DC power preference, PDU redundancy and any data-centre access constraints.
Supply only, installation, configuration, policy migration, VPN migration, testing, cutover, training or ongoing support.
Build the right Cisco Secure Firewall 3100 configuration for your UAE network
A useful quote should answer more than “which chassis?” It should show why the selected 3100 model fits the inspected workload, which ports and optics connect to the existing network, how VPN and TLS demand were accounted for, what licences deliver the required controls, how failure is handled and what work is included in the deployment. Share your traffic, interface, licence and migration requirements and FourTeck can structure the 3105, 3110, 3120, 3130 or 3140 comparison around those facts.
