Fortinet FortiGate 3500G Firewall in Dubai, UAE
The FortiGate 3500G is designed for organisations that need security inspection at data-center scale rather than branch-office capacity. It combines very high firewall, VPN, IPS and encrypted-traffic performance with a dense 25G, 100G and 400G interface mix, making it suitable for enterprise perimeter, internal segmentation, cloud interconnect, regional aggregation and east-west inspection designs where traffic growth has outpaced older firewall platforms.
Before requesting pricing
Prepare internet and inter-zone bandwidth, inspection requirements, port speeds, optics, HA design, license term, logging plan and migration scope. These details determine the correct bill of materials more reliably than headline throughput alone.
Direct answer for buyers considering the FortiGate 3500G
Fortinet FortiGate 3500G is a high-end data-center next-generation firewall for organisations that need very large session scale, high-speed IPsec, deep security inspection and connectivity up to 400GbE. It should be considered when a conventional enterprise firewall no longer provides enough inspected throughput or interface density for a core, data-center edge or large segmentation project. Before proceeding, buyers should confirm actual traffic patterns, SSL inspection requirements, VPN load, transceiver types, high-availability design, FortiGuard services, support term, logging architecture, firmware compatibility and whether onboard storage is required. The storage-equipped sibling is the FG-3501G, so the exact model must be stated on the quotation and purchase order.
Applies security controls at data-center traffic scale
The appliance sits between high-capacity network zones and applies firewall policy, intrusion prevention, application control, malware protection, VPN and encrypted-traffic inspection according to configuration and subscribed services. Its purpose is not simply to pass hundreds of gigabits of traffic. The buying value comes from retaining enough capacity after the security functions required by the organisation are enabled.
Large enterprises, data centers and high-density networks
This model is most appropriate where the network has high-speed backbone links, large numbers of simultaneous sessions, heavy encrypted traffic, multiple internal security zones, large VPN aggregation requirements or a need to consolidate several security enforcement points. A branch office, modest campus or small internet edge is unlikely to justify this class of appliance unless it is part of a special architecture with unusually demanding traffic requirements.
Business problems the 3500G can help address
High-end firewall projects are usually triggered by a practical constraint rather than by a desire to buy the largest appliance. The FortiGate 3500G becomes relevant when existing security infrastructure is beginning to limit application performance, segmentation design or future network growth. The cards below describe the kinds of problems that should prompt evaluation of this model while keeping the final decision tied to measured requirements.
Inspection bottlenecks
A firewall that meets raw packet-forwarding requirements may fall short after IPS, application control, malware protection and SSL inspection are enabled. Sizing should therefore use the security profile that will actually run in production.
Fast east-west growth
AI clusters, private cloud, virtualisation and distributed applications can increase traffic between internal zones. A data-center firewall may need to inspect those flows without becoming the lowest-speed component in the path.
Dense backbone links
Networks moving to 100GbE or 400GbE require security appliances with an interface plan that matches the switching fabric. Optics, breakout design and redundancy should be validated before ordering.
Session-scale pressure
Very large user, service and application estates can create millions of simultaneous connections. Session count and connection setup rate matter as much as bandwidth when the firewall protects busy public or private application environments.
Core capabilities that matter to an enterprise buyer
Is the FortiGate 3500G the right class for the requirement?
| Requirement | Suitable when | Confirm before ordering |
|---|---|---|
| Data-center perimeter | Internet or partner links require inspected capacity well beyond mid-range firewall levels. | Peak bandwidth, security profiles, DDoS architecture, uplink speeds, HA design. |
| Internal segmentation | Large east-west flows need policy enforcement between server, user, OT, cloud or tenant zones. | Routing design, VLAN/VXLAN architecture, session count, inspection depth. |
| Regional VPN hub | Many remote sites or high-bandwidth tunnels aggregate into one security platform. | Tunnel count, crypto suite, routing, redundancy, expected encrypted throughput. |
| 400GbE security insertion | The backbone roadmap includes 400Gb links and the firewall must participate directly. | Optics, cabling, breakout requirements, switch compatibility and port allocation. |
| Local logging requirement | The project specifically needs onboard SSD capacity in the appliance. | Evaluate FG-3501G rather than assuming the base FG-3500G includes local storage. |

Configuration, licensing and compatibility dependencies
The appliance specification does not by itself define the finished solution. FortiGuard security functions, support services, central management, logging, optics and implementation services can be separate quotation items or part of selected bundles. A buyer should not assume that every Fortinet security service is enabled merely because the hardware supports it. The required service set should be matched to the organisation’s policy objectives and budget, then confirmed against the current ordering structure.
Firmware compatibility also matters because the 3500G is a newer platform. Fortinet release notes identify the model as introduced on specific FortiOS builds. Organisations with standardised software versions, certified change baselines or older management platforms should verify supported combinations before the appliance enters production. Optics and cabling require the same discipline. A QSFP-DD slot tells you the interface family, but the exact transceiver, reach, fibre type, breakout behaviour and connected switch support still have to be validated. FourTeck can help convert these dependencies into a clearer bill of materials and implementation checklist rather than leaving procurement to infer them from interface counts.
A practical purchase and deployment journey
Measure the current network
Capture internet, WAN and inter-zone traffic, peak sessions, new connections per second, current inspection profile and growth assumptions. Use production evidence wherever possible.
Design interfaces and HA
Map 25G, 100G and 400G links, HA ports, management, transceivers, rack positions, power feeds and failure scenarios before ordering optics or cables.
Choose services and support
Select FortiGuard functions, FortiCare term, central management, logging and any professional services required. Confirm what is included versus optional.
Plan the migration
Define route, VLAN, NAT, VPN and policy migration, testing, rollback, maintenance window, monitoring, certificate changes and stakeholder sign-off.
Validate after cutover
Check application paths, failover, security profiles, log delivery, VPNs, policy hits, CPU and session behaviour, then capture the final configuration and documentation.
Capability focus: performance that still matters after security is enabled
The headline 595 Gbps firewall throughput is useful for understanding the scale of the platform, but it is not the number most security architects should use on its own. A production deployment can include IPS, application control, malware inspection, logging, SSL inspection and multiple policy layers. Fortinet therefore publishes additional enterprise-mix figures that better illustrate capacity when security functions are active. For the 3500G, the current product matrix lists up to 125 Gbps IPS, 115 Gbps NGFW and 105 Gbps threat protection. These numbers are still laboratory measurements, but they provide a more responsible starting point for comparing the platform with an actual security policy.
A useful sizing exercise separates traffic into categories. Some flows may require full SSL inspection, some may only need certificate inspection, some internal application traffic may need IPS without web filtering, and certain backup or replication paths may have different controls. This segmentation helps estimate the inspected throughput that will run at the busiest time. It also prevents oversizing solely on internet bandwidth or undersizing because an old firewall appeared comfortable before advanced inspection was enabled. FourTeck can help structure these questions during product sizing, but the final target should always reflect the customer’s network measurements, security policy and growth plan.
Capability focus: 400Gb connectivity without ignoring the optics plan
The FortiGate 3500G provides two 400GE QSFP-DD interfaces alongside four 100GE QSFP28 and thirty 25GE SFP28 interfaces, plus 10GE RJ45 management connectivity. For a data-center buyer, this is significant because the firewall can be inserted into architectures that have moved beyond traditional 10G or 40G aggregation. The interface list, however, should be treated as a design canvas rather than a promise that every port will be used in any desired combination without planning. Port allocation must account for HA, north-south links, internal zones, service chains, management access, link aggregation and future expansion.
Optics can become a material part of the project cost and schedule. The exact transceiver depends on link speed, distance, fibre type, connector, switch support and whether breakout is planned. Procurement teams should therefore request an interface schedule with the quotation: source device, destination device, speed, media, optic on each side, cable type and redundancy role. That approach reduces the risk of receiving the correct firewall but an incomplete connectivity bill of materials. It also makes installation planning clearer for the network team, especially when 100G and 400G links cross between racks, meet-and-me rooms or data-center zones.
Capability focus: session scale, segmentation and operational control
The published maximum of 179 million concurrent sessions and up to 1.1 million new sessions per second illustrates why the 3500G is positioned for very large environments. Session scale is important in modern application estates because bandwidth alone does not describe the work a firewall performs. Public services, API platforms, cloud applications, content systems, large campuses and service-provider environments can create extremely high connection counts even when individual flows are small. A platform that has enough throughput but insufficient session headroom can still become constrained.
Segmentation can multiply this requirement because a data-center firewall may inspect many east-west flows in addition to north-south internet traffic. Organisations should map which internal zones need enforcement, how routing is performed, whether virtual domains are required, how policies will be managed and where logs will be retained. The 3500G supports a high VDOM ceiling in Fortinet’s matrix, but using large numbers of logical domains increases operational complexity and should be justified by tenancy, administrative separation or architecture. Centralised policy management and analysis tools may be useful in larger Fortinet estates; their sizing and licensing should be reviewed as part of the overall design rather than added after the firewall is installed.
Ideal business environments and use cases
Large enterprise data centers
A suitable fit where the firewall must protect high-bandwidth internet, partner, cloud and internal application paths while maintaining substantial inspection capacity and dense optical connectivity.
AI and accelerated computing environments
Relevant where AI-related east-west traffic and encrypted application flows are increasing security demands. Buyers should define which AI traffic must be inspected and controlled instead of assuming all workloads use the same policy.
Regional VPN and service aggregation
Can be evaluated as a central platform for large numbers of site-to-site tunnels or high-bandwidth encrypted connections, subject to routing design, crypto choices and redundancy requirements.
Internal segmentation firewalls
Useful where security controls must be inserted between major data-center zones, tenant networks or sensitive application tiers and ordinary perimeter appliances cannot provide enough inspected capacity.
Large campus or headquarters core
May suit unusually large campus environments with very high backbone speeds, extensive segmentation and centralised policy enforcement. A smaller FortiGate should still be considered if actual capacity requirements are lower.
Service-provider security zones
Potentially relevant for provider infrastructures that need high session scale, IPsec aggregation, customer separation or security insertion at high speeds. Carrier-specific features and licensing must be validated for the project.
Integration and operational considerations
A firewall of this class is rarely a standalone appliance. It usually sits within a wider architecture that includes core switches, routers, internet or MPLS links, cloud connectivity, identity systems, SIEM or log platforms, network-management tooling and change-control processes. The procurement decision should therefore include operational questions as early as performance questions. Which team owns firewall policy? Where are logs stored? How long are they retained? Will centralised management be used? How are certificates distributed for deep inspection? What is the patch and firmware process? Who owns the rollback decision during migration? These questions determine whether the platform can be operated consistently after it is installed.
FortiManager and FortiAnalyzer are commonly evaluated in larger Fortinet environments for central policy control, logging, reporting and operational visibility, but the correct platform size and license depend on the number of devices, log volume, retention and required features. They should not be assumed to be included with the firewall hardware. The same applies to FortiGuard service bundles. Fortinet offers services in bundles and as individual subscriptions, so the quotation should clearly state the security package, term and support level.
High availability also requires more than ordering two appliances. Both units should have aligned hardware, software, licensing, interfaces and cabling, and the design must account for upstream and downstream switch behaviour, link aggregation, routing convergence, session handling and maintenance. A test plan should verify failover under realistic traffic and application conditions. FourTeck can include installation and configuration planning in the discussion when required, but the exact service scope should be written into the quotation rather than assumed.
Buyer questions to resolve before requesting a final quote
Separate internet, VPN, east-west, partner, backup and application flows. Identify where IPS, malware scanning, application control and SSL inspection will be active.
List every 25G, 100G and 400G link, including HA and management, then identify optics, fibre, distances and connected switch models.
The storage-equipped model is FG-3501G. If local logging is a requirement, confirm whether that variant or an external logging platform is more appropriate.
Do not select a subscription bundle only by name. Confirm which security functions the policy requires and how long the organisation wants the service term to run.
Decide whether policies will be rebuilt, converted or migrated in phases. Include NAT, VPN, routing, objects, certificates, logging and rollback procedures.
Because the 3500G is a newer platform, validate the supported firmware release and compatibility with management, logging and operational standards before go-live.
Procurement checklist for the FortiGate 3500G

✓ Specify transceivers, fibre type, distance and breakout needs.
✓ Select FortiGuard services and subscription term.
✓ Confirm FortiCare support level and term.
✓ Confirm FortiOS release and platform interoperability.
✓ Define FortiManager, FortiAnalyzer or other logging requirements.
✓ Validate rack space, airflow, power feeds and cabling route.
✓ Decide policy migration, testing and rollback responsibilities.
✓ State installation, configuration and documentation scope.
✓ Confirm destination, required date and current vendor lead time with FourTeck.
How FourTeck can assist with sizing and quotation preparation
For a high-end firewall, the most useful sales conversation is a requirement review rather than a model-only price request. FourTeck can help organise the information needed to quote the FortiGate 3500G accurately: appliance quantity, exact model, license package, support term, interface optics, central management, log handling, migration services and delivery destination. This does not replace the customer’s architecture process; it helps turn that process into a clear bill of materials that procurement can evaluate.
If the customer is replacing an existing FortiGate or another vendor platform, the discussion can also include policy migration, VPN transfer, HA design, test planning, maintenance window and documentation requirements. Installation and configuration support should be priced as a defined scope where required. For broader cybersecurity planning, buyers can review FourTeck firewall services or the Fortinet firewall guidance page.
Information to send FourTeck
Current firewall model, required quantity, peak bandwidth, inspection profile, VPN scale, port plan, HA requirement, subscription preference, target destination, migration scope and desired project window.
UAE availability and support guidance
Contact FourTeck to confirm current UAE availability for the Fortinet FortiGate 3500G. Availability may depend on the exact model, appliance quantity, FortiGuard or FortiCare bundle, required optics, regional licensing and current vendor lead time. A large data-center appliance may also involve project-specific procurement approval, so the delivery schedule should be discussed after the exact bill of materials is confirmed rather than inferred from a generic product listing.
For buyers in Dubai and the wider UAE, FourTeck can coordinate quotation preparation, product and license selection, delivery planning and an agreed installation or configuration scope where required. The commercial quotation should state whether services, transceivers, rack work, migration, documentation or after-deployment support are included. Buyers can use the FourTeck contact page to share the project requirement and request current options.
Dubai, Abu Dhabi, Sharjah and Ajman project coverage
FourTeck can discuss FortiGate 3500G requirements for organisations operating across Dubai, Abu Dhabi, Sharjah and Ajman within one coordinated UAE procurement and project conversation. A Dubai data center may prioritise high-speed internet and cloud interconnects, while an Abu Dhabi enterprise may have a different segmentation, regulatory or redundancy design. Manufacturing and distribution groups in Sharjah or Ajman may be centralising security for several sites. The appliance should not be selected solely because the business is large; it should be selected when measured traffic, inspection and interface requirements justify this class. Share the deployment location, data-center connectivity, required quantity, security services, support term and project schedule so FourTeck can help align the model, licensing and delivery plan with the actual UAE environment.
GCC Availability
For GCC projects, the FortiGate 3500G may be evaluated where regional headquarters, data centers or service-provider environments require high-capacity security and a consistent operating model across multiple countries. FourTeck can help organisations review the exact requirement, model selection, FortiGuard and FortiCare terms, optics, central management, quotation structure, delivery planning and implementation scope for projects that may involve the United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain or Oman. The relevant commercial and technical details should be confirmed for each destination rather than copied from a UAE bill of materials without review.
Product availability, license eligibility, delivery schedules, service visits and vendor lead times can vary by country, quantity and project scope. Buyers should provide the destination country, appliance quantity, preferred subscription term, intended data-center location, high-availability requirement, interface plan and expected timeline. Where Kuwait is part of the requirement, FourTeck’s Kuwait technology resource can support regional coordination discussions. No local inventory or fixed delivery date should be assumed until the exact requirement has been confirmed.
Africa Availability
African organisations sourcing enterprise security through regional or Dubai procurement channels can also discuss FortiGate 3500G requirements with FourTeck. This model is most relevant to high-capacity data centers, large financial or service platforms, telecommunications environments, government infrastructure, cloud hosting and other networks where measured traffic and inspection requirements are well above typical branch-firewall levels. FourTeck can assist with requirement review, appliance and subscription selection, accessory planning, quotation preparation, configuration scope, renewal considerations and project coordination.
Fulfilment can depend on destination country, model and quantity, license region, power and rack requirements, shipping arrangements, vendor lead time and local implementation conditions. Buyers should share the destination, exact appliance requirement, quantity, desired subscription term, preferred deployment schedule and whether installation or remote configuration assistance is expected. For East Africa or wider regional enquiries, the FourTeck Africa resource provides an additional route for project discussion. Inventory, customs outcomes, onsite coverage and delivery dates must be confirmed for each requirement.

Migration and configuration support
Useful when replacing an existing firewall, rebuilding rules, transferring VPNs or validating HA and logging. Review the FourTeck services page for planning discussions.
Why businesses contact FourTeck for this class of firewall
A high-end appliance purchase can fail at the small details: the wrong storage variant, a missing optic, an unsuitable subscription term, an unsupported firmware assumption, an incomplete HA cable plan or a migration scope that was never assigned. FourTeck’s role is to help buyers turn technical requirements into a procurement-ready discussion. That can include model clarification, bill-of-material review, security subscription guidance, compatibility questions, quotation coordination, installation planning, migration scope and renewal considerations.
The emphasis is practical rather than promotional. FourTeck cannot determine the right firewall size without knowing the traffic and policy requirements, and current stock or lead time must be checked for the actual project. Buyers who need a broader view of Fortinet products can use the Fortinet UAE resource, while general company information is available through Firewall Dubai by FourTeck.
What enterprise buyers usually need to know before shortlisting the 3500G
When buyers research the FortiGate 3500G, the first question is often whether it is “fast enough.” A better question is whether its inspected performance matches the workload that will actually cross it. The published firewall figure reaches 595 Gbps, but a security design may also enable IPS, application control, malware protection, logging and SSL inspection. Fortinet publishes separate enterprise-mix values for those conditions, including 125 Gbps IPS, 115 Gbps NGFW and 105 Gbps threat protection. Those values make the model easier to evaluate against a real security policy. A buyer with 80 Gbps of internet traffic but very heavy SSL inspection may have a different sizing outcome from a buyer with 150 Gbps of mostly trusted inter-data-center traffic. Both environments need headroom, but the bottleneck is not necessarily the same.
The two models share a broad high-end data-center role, but the 3500G has materially higher published IPS, NGFW and threat-protection performance and adds 400GE QSFP-DD connectivity. Do not treat them as interchangeable just because the model number is similar.
The storage distinction is important. Fortinet’s matrix associates the 3501G variant with two 1.92 TB drives. If local storage is part of a logging or operational requirement, specify the exact storage variant rather than expecting it in the base appliance.
Another recurring buying question is whether the 400Gb ports make the model appropriate for any 400Gb network. The answer depends on architecture. A firewall can have 400GE interfaces and still need a carefully designed port map. Network teams should decide whether each QSFP-DD port connects directly to core switches, data-center spines, routers or another security layer; whether links operate at full rate or use supported breakout; and how high availability affects the connection count. Transceiver selection should be part of this design. The cost and lead time of high-speed optics can be significant, so leaving them out of the first quotation creates an incomplete procurement picture.
Security services are another area where buyers search for a simple answer but encounter dependencies. FortiGuard services are offered in different bundles and can also be available individually. The right selection depends on the controls that will be enabled. A buyer should therefore map requirements such as intrusion prevention, malware inspection, web security, application control and other subscribed functions to the current bundle structure. FortiCare support should be reviewed separately for the desired support term. For a multi-year project, subscription renewal dates and budget planning are worth deciding before purchase, especially when the appliance will protect critical infrastructure.
Encrypted traffic inspection deserves particular attention because modern data centers carry a large proportion of TLS traffic. Fortinet’s current matrix lists 112 Gbps SSL inspection throughput for the 3500G under its stated test profile. Real environments can vary because cipher suites, certificate handling, object size, connection reuse and policy structure affect processing. Deep inspection also requires an organisational certificate strategy. The firewall may technically support the throughput, but endpoints must trust the inspection certificate and applications with certificate pinning or special compliance rules may need exceptions. These operational details are often more important to a successful rollout than the raw number.
Buyers also ask whether the FortiGate 3500G is “for AI.” Fortinet introduced the model in the context of growing AI workloads, encrypted east-west traffic and data-center security. That makes it relevant to networks carrying AI-related traffic, but the firewall is not limited to AI deployments. Its broader role is high-performance security enforcement. An organisation should still define what it needs to control: traffic between AI compute nodes, north-south access to model services, external API calls, user access to AI applications, sensitive data movement or ordinary data-center segmentation. The policy requirement comes first; the platform capacity supports that requirement.
Price research for a device in this class can be confusing because search results mix hardware-only offers with one-, three- or five-year security bundles, different currencies and regional reseller terms. A visible online price should not be treated as a UAE selling price unless the SKU, license term, taxes, support, optics and region all match. For an accurate FourTeck quotation, provide the exact model, quantity, license package, support term, destination, optics and service scope. That gives procurement a comparable offer rather than a number that cannot be reconciled with the intended configuration.
Decisions that change the bill of materials
How much headroom should we leave above current traffic?
Headroom should cover traffic growth, policy expansion, failover conditions and the possibility that more encrypted traffic will require inspection later. There is no universal percentage. Review peak utilisation, three- to five-year network plans and the security services that will run, then size against the relevant inspected-throughput figure rather than only the raw firewall number.
Do we need two appliances or can we start with one?
A single appliance may meet capacity requirements, but critical data-center designs often require redundancy. The HA decision depends on acceptable downtime, change windows, network topology and failure scenarios. If HA is required, budget for matching hardware, licenses, optics, cabling and upstream/downstream design from the beginning.
Can we reuse existing 100G optics and cabling?
Possibly, but reuse should never be assumed from speed alone. Confirm the transceiver type, wavelength, fibre, reach, connector, vendor support and connected switch. If the architecture is moving to 400G, determine whether new QSFP-DD optics or breakout assemblies are required and include them in the quotation.
Should we choose the 3501G because it has storage?
Only if onboard storage is part of the operational design. Large environments often use central logging, so local storage may or may not be a deciding factor. Compare the logging architecture, retention needs, FortiAnalyzer design and resilience requirements before changing the model solely for storage.
What information does procurement need for a comparable quote?
Ask each quotation to state appliance SKU, quantity, subscription bundle and term, FortiCare level, optics, cables, central-management components, implementation services, delivery destination and commercial validity. Without that structure, a lower price may simply represent fewer included items rather than a better commercial offer.
When should migration services be included?
Include migration assistance when the internal team does not want to own every step of rule conversion, route and VPN transfer, testing, cutover and rollback. The scope should specify what FourTeck will configure, what the customer supplies, how testing is performed and whether documentation is part of the handover.
Frequently asked questions
What is the Fortinet FortiGate 3500G mainly used for?
It is mainly used as a high-capacity next-generation firewall for data-center perimeter security, internal segmentation, regional VPN aggregation and other enterprise environments that need substantial inspected throughput and high-speed interfaces.
What is the published threat-protection throughput of the FortiGate 3500G?
Fortinet’s current product matrix lists up to 105 Gbps threat-protection throughput using its enterprise-mix profile with firewall, IPS, application control, malware protection and logging enabled. Real performance depends on traffic and configuration.
Does the FortiGate 3500G have 400 Gigabit Ethernet ports?
Yes. The published interface list includes two 400GE QSFP-DD ports, four 100GE QSFP28 ports, thirty 25GE SFP28 ports and two 10GE RJ45 ports. Exact optics and cabling must be selected for the connected network.
What is the difference between FG-3500G and FG-3501G?
The key ordering distinction is local storage. Fortinet’s matrix associates the FG-3501G storage variant with two 1.92 TB drives, while the base FG-3500G is the non-storage model. Confirm the exact SKU before ordering.
Are FortiGuard subscriptions included with the hardware?
Do not assume they are included. FortiGuard services are subscription dependent and offered through different bundles or individual services. The quotation should state exactly which services and term are included.
Can the FortiGate 3500G inspect encrypted traffic?
Yes. Fortinet publishes SSL inspection performance for the model, with the current matrix listing up to 112 Gbps under its stated IPS and average HTTPS test profile. Production results depend on ciphers, certificates, policies and application behaviour.
Is FortiOS version planning important for the 3500G?
Yes. The 3500G is a newer platform introduced on specific FortiOS builds, so the target firmware should be validated against Fortinet release notes and the customer’s management, logging and change-control requirements before deployment.
Can FourTeck assist with installation and migration?
FourTeck can discuss installation, configuration and migration assistance based on an agreed project scope. The quotation should define responsibilities for rack work, policy migration, routing, VPNs, testing, rollback and documentation.
How can I request current FortiGate 3500G pricing and UAE availability?
Send FourTeck the exact model, quantity, required license and support term, port and optics plan, destination and service scope. FourTeck can then confirm current UAE availability and prepare a project-specific quotation.
Prepare a complete FortiGate 3500G quotation request
Share your target bandwidth, inspection profile, link speeds, HA requirement, appliance quantity, subscription term, logging approach, deployment destination and migration needs. FourTeck can use that information to help confirm the correct model and assemble a clearer UAE quotation.
