Enterprise identity infrastructure for high-scale environments
Fortinet FortiAuthenticator 3000F in Dubai, UAE
FortiAuthenticator 3000F, model FAC-3000F, is a 2RU hardware appliance for organisations that need centralised identity, authentication, certificate and access services across large populations of users and network devices. It brings RADIUS, TACACS+, multi-factor authentication, single sign-on, certificate management, guest services and federation capabilities into a dedicated platform that can integrate with Fortinet infrastructure as well as third-party identity sources.
Plan the correct FAC-3000F configuration
For an accurate quotation, confirm the expected user population, RADIUS and TACACS+ client count, FortiToken requirements, SSO method, directory integrations, certificate workload, high-availability design and support expectations. New projects should also compare the current 3000F requirement with Fortinet’s newer 3000G platform before finalising the bill of materials.

Identity, AAA, MFA, SSO and certificate services
Direct answer for buyers
FortiAuthenticator 3000F is Fortinet’s high-capacity F-series identity and access management appliance for centralising authentication and identity services. It is mainly used to provide RADIUS and TACACS+ AAA, multi-factor authentication, Fortinet Single Sign-On, SAML and OIDC federation, certificate management, guest access and integration with directory services such as Active Directory and LDAP. It is most appropriate for large organisations with substantial user, device or network-authentication requirements. Before proceeding, a buyer should confirm the licensed user target, RADIUS or TACACS+ client scale, token and SSO requirements, high-availability architecture, required integrations, support term and whether the newer FAC-3000G is a better fit for a fresh deployment.
What the appliance does
The FAC-3000F acts as a central identity and authentication authority for enterprise network access. It can authenticate users against local records and external identity sources, apply multi-factor authentication, provide RADIUS and TACACS+ services, participate in 802.1X access workflows, issue and manage certificates, federate identities through SAML and OIDC, support guest access and share identity information with FortiGate for policy enforcement. For organisations with several firewalls, VPN gateways, wireless networks, switches and business applications, centralising those functions can reduce the number of independent authentication systems that administrators must maintain.
The appliance is not a firewall and should not be selected as a replacement for a FortiGate. Its purpose is to strengthen and organise identity verification and access control around the network and applications that already exist. Its value is highest when the organisation has enough scale, integration complexity or compliance pressure to justify a dedicated identity appliance rather than relying on authentication functions spread across multiple systems.
Who should consider it
The 3000F is primarily aimed at large enterprises and other high-user-count environments. It is especially relevant when an organisation expects tens of thousands of users, many RADIUS clients, extensive certificate use, multiple FortiGate devices, distributed offices, large remote-access populations or centralised administrative authentication. It may also suit universities, large healthcare groups, government environments, financial organisations, managed service environments and multi-site businesses where authentication consistency matters across different networks.
It is usually excessive for a smaller company that only needs authentication for a few hundred or a few thousand users. In those situations, smaller FortiAuthenticator hardware, virtual or cloud options may be more appropriate. FourTeck can help compare the capacity requirement rather than assuming the largest model is automatically the correct choice.
Business problems the FortiAuthenticator 3000F can help address
Fragmented authentication
When VPN, wireless, firewall administration and internal applications each use separate user stores or authentication policies, operations become harder to govern. FortiAuthenticator can centralise several of these identity workflows so policy and user information are handled more consistently.
Weak password-only access
The platform supports multi-factor authentication with FortiToken and other supported methods, allowing organisations to add a second factor to selected access workflows. Token licensing and the exact authentication method must be included in the design rather than assumed to be part of the appliance purchase.
Inconsistent network identity
Fortinet Single Sign-On and RADIUS accounting can help associate users with network activity so FortiGate policies can use identity information. The correct collection method depends on the directory design, endpoints, FortiClient use and the organisation’s network architecture.
Certificate administration overhead
Certificate-based VPN, wireless and device-authentication projects can become difficult when enrolment, signing, renewal and revocation are managed manually. FortiAuthenticator includes certificate management capabilities and supports protocols such as SCEP for automated enrolment workflows.
Identity capacity designed for enterprise scale
The clearest reason to evaluate the FAC-3000F rather than a smaller FortiAuthenticator appliance is capacity. The base license supports 40,000 local and remote users, and Fortinet documents an upper limit of 240,000 users through FortiAuthenticator hardware upgrade licenses. The platform also supports up to 80,000 FortiTokens, 8,000 user groups, 50 CA certificates and 200,000 user certificates. RADIUS client capacity begins at 13,333 and can rise to 80,000 within the standard hardware scaling model. Fortinet also lists an Advance/Carrier license for FAC-3000F and FAC-3000G that provides unlimited RADIUS and TACACS+ clients.
These numbers should be treated as design limits, not as a reason to size solely on the largest headline value. A production design should consider peak authentication rates, the number of independent network access devices, directory lookup patterns, SSO collection methods, certificate operations, high-availability requirements and projected growth. A buyer with 35,000 users today may still want a 3000F if growth or network-device scale justifies it, while another organisation with the same user count may be better served by a different architecture if its authentication pattern is simple.
FourTeck can use the present user count and a realistic three-to-five-year projection to determine which hardware upgrade licenses should be ordered initially and which can be deferred. This helps avoid both under-sizing and purchasing capacity that is unlikely to be used.
Centralised AAA for network access
FortiAuthenticator supports RADIUS and TACACS+ so it can serve as a central Authentication, Authorization and Accounting platform for network access and administrative logins. RADIUS is commonly used for VPN, wireless and 802.1X access, while TACACS+ is often selected for administrative authentication and command control on supported network infrastructure. Consolidating these functions can make it easier to apply consistent identity policy across firewalls, switches, wireless controllers and other compatible systems.
The exact design matters. Buyers should list every expected RADIUS and TACACS+ client, identify which systems need accounting, determine whether network-device command authorisation is required and confirm the authentication source for each user population. If client scale is unusually high, the standard RADIUS client limits and the optional Advance/Carrier license should be evaluated before purchase.
MFA, federation and single sign-on
The appliance can support multi-factor authentication, SAML identity-provider functions, OIDC provider functions, Fortinet Single Sign-On and integration with external identity systems. These capabilities allow the same platform to participate in both network authentication and application-access workflows. FortiToken can be used for one-time-password or push-based MFA scenarios, while FIDO can support passwordless or strong-factor use cases where the surrounding application flow supports it.
Licensing and integration dependencies are important. FortiToken hardware and software tokens are purchased separately. The FortiClient SSO Mobility Agent requires its own license. SMS-based authentication may require a FortiGuard SMS license or a supported third-party gateway. Buyers should map each user group to its intended authentication method before the quotation is finalised.
Certificate and PKI workflows
FortiAuthenticator includes certificate management functions that can support server and user certificates, certificate signing, revocation and automated enrolment. Fortinet documents support for X.509, PKCS#10 certificate requests, PKCS#12 import, OCSP, SCEP and related certificate processes. This can be valuable for organisations that use EAP-TLS for 802.1X, certificate-based VPN access, internal HTTPS services or other identity workflows where certificates are preferable to passwords.
The appliance is not a substitute for every enterprise PKI requirement. Organisations with an established Microsoft CA, third-party PKI or complex certificate policy should define whether FortiAuthenticator will operate as a CA, subordinate service, enrolment point or authentication consumer. That decision affects migration effort, trust relationships and operational procedures.

Licensing, token and integration dependencies
The hardware appliance is only one part of a complete FortiAuthenticator deployment. Capacity above 40,000 users requires the appropriate FortiAuthenticator hardware upgrade licenses. Fortinet lists 100-user, 1,000-user, 10,000-user and 100,000-user hardware upgrade SKUs for compatible models, including the 3000F. The correct combination should be calculated against the licensed-user target rather than added without a sizing plan.
FortiToken hardware and software tokens are separate purchases. Organisations using the FortiClient SSO Mobility Agent also need the corresponding FortiAuthenticator SSO agent license. SMS authentication may need FortiGuard SMS licensing or a supported third-party SMS gateway. FIDO hardware tokens are separate. The optional FortiAuthenticator Advance/Carrier license is applicable to FAC-3000F and FAC-3000G and is relevant when the project requires unlimited RADIUS and TACACS+ clients.
Directory integration should be reviewed before implementation. FortiAuthenticator can integrate with Active Directory and LDAP, but the required connectivity, DNS, time synchronisation, certificates, service accounts and group mappings should be validated as part of the project design. SAML and OIDC integrations similarly require application-specific configuration. A feature being supported by FortiAuthenticator does not mean every third-party application will automatically interoperate without testing.
For high availability, plan for two suitably licensed appliances and confirm the intended Active-Passive HA or configuration-synchronisation design. Rack units, power feeds, network interfaces, VLANs, management addressing and backup procedures should be included in the infrastructure plan. If you need assistance defining the scope, FourTeck’s technology services team can help structure installation and configuration requirements for quotation.

How the FAC-3000F supports different identity strategies
1. Identity-aware access across Fortinet infrastructure
In a Fortinet-focused environment, FortiAuthenticator can become the common identity source behind VPN authentication, administrator access, wired and wireless network authentication and identity-aware FortiGate policy. Fortinet Single Sign-On can collect identity information and share it with FortiGate so policies can reference users and groups instead of relying only on IP addresses. This is particularly useful in large networks where employees move between offices, wired and wireless networks or VPN connections.
The design should identify which identity collection mechanism is appropriate. Active Directory polling can work in some domain environments, while the SSO Mobility Agent may be better where endpoints roam or where direct polling is not practical. RADIUS accounting can provide another identity source in networks already using RADIUS. There is no single method that is ideal for every environment, so the collection approach should be tested against directory design, endpoint ownership and operational visibility requirements.
2. Stronger authentication without redesigning every application
A common reason to deploy FortiAuthenticator is to add stronger authentication around systems that already use RADIUS, SAML, OIDC or supported agents. Rather than implementing a separate MFA platform for each VPN gateway or application, the organisation can centralise identity verification and apply a consistent second factor. This can simplify policy administration, token lifecycle management and support for users who access several systems.
The important limitation is application compatibility. Some legacy systems may support only a narrow set of RADIUS methods. Others may require SAML or OIDC configuration. Certain user populations may need hardware tokens, while others can use mobile tokens or FIDO. An effective rollout starts with an application inventory, groups systems by authentication protocol and chooses a factor suitable for each risk level and user experience.
3. Certificate-based identity for network and remote access
Certificate authentication is attractive where organisations want to reduce dependence on reusable passwords, particularly for managed endpoints, enterprise Wi-Fi and VPN access. FortiAuthenticator can issue, sign, revoke and manage certificates and supports automated enrolment protocols such as SCEP. It can also participate in EAP-TLS workflows for 802.1X network access.
Certificate projects require more planning than simply turning on a feature. The organisation needs a documented trust model, certificate templates, enrolment rules, revocation handling, renewal intervals and a plan for lost or re-imaged devices. Existing PKI investments should be taken into account. In some environments, FortiAuthenticator may be the central certificate authority; in others it may work alongside an established enterprise CA. FourTeck can help identify the integration questions that should be resolved before implementation effort is quoted.
Ideal business environments and use cases
Large enterprise campus
A campus with thousands of employees, many switches, wireless access points, VPN users and privileged administrators can use the 3000F to centralise AAA and identity services. The key sizing factor is not only employee count but also the number of network access devices and authentication paths.
Distributed regional organisation
A business operating many offices can use central authentication and identity sharing to create more consistent access policy across locations. WAN resilience, local failure modes and high-availability design should be considered before centralising all sites on one authentication service.
Higher education
Universities may have large numbers of students, staff, guests, devices and wireless authentication events. RADIUS, guest access, certificate authentication and federation can all be relevant, but academic identity systems and roaming requirements should be reviewed for compatibility.
Healthcare and regulated operations
Hospitals and multi-site healthcare groups often need strong administrator access, staff authentication, certificate-based devices and auditable identity controls. The appliance can support these identity functions, while the broader compliance design remains dependent on application, process and policy controls beyond FortiAuthenticator.
Service provider or very high NAS scale
The 3000F’s high RADIUS client capacity and optional Advance/Carrier license can be relevant where an unusually large number of NAS or TACACS+ clients must authenticate through a common service. Exact use should be validated against the service model and support requirements.
Fortinet Security Fabric expansion
Organisations already using FortiGate, FortiSwitch, FortiAP and FortiClient can use FortiAuthenticator to strengthen the identity layer that connects those components. The purchase should still be justified by the actual identity architecture rather than brand alignment alone.
Operational and integration considerations
Identity services sit directly in the login path, so operational planning is as important as hardware capacity. Start with name resolution and time synchronisation. Directory authentication, certificates, SAML assertions and token workflows are all sensitive to DNS or time errors. Management interfaces should be placed on appropriate secured networks, and administrator access should use strong authentication with role separation where possible.
Active Directory and LDAP integrations require network reachability, service-account design, group mapping and a clear understanding of which directory is authoritative. If several forests or domains are involved, test referral behaviour and group lookups. For SAML or OIDC, document each relying party or service provider, callback URL, certificate and claim mapping. For RADIUS, standardise shared-secret handling, source addresses, accounting settings and failover behaviour.
High availability should be designed around the business impact of authentication loss. Active-Passive HA can reduce appliance-level risk, but it does not automatically address every failure domain. Consider separate power feeds, network paths, switches and racks where appropriate. If remote branches depend on a central authentication pair, determine how users will access critical resources during WAN disruption.
Logging and monitoring should also be incorporated from the start. Authentication failures can indicate user mistakes, configuration errors or security events. Define how logs will be retained and reviewed, whether they need to be forwarded to a central logging or SIEM platform, and who owns operational response. Backups and configuration export procedures should be documented and tested.
Before production migration, create a small pilot group and validate every intended authentication route: VPN, wireless, wired 802.1X, network administration, SSO, application federation and certificate enrolment as applicable. A controlled pilot helps identify compatibility problems before they affect the wider organisation.
Questions to resolve before requesting a quotation
An accurate FAC-3000F quotation depends on more than the appliance part number. Procurement and technical teams should agree the intended design so hardware, user upgrades, token licenses, support and services can be quoted together.
How many active local and remote users will be licensed at deployment, and what growth is expected during the planned lifecycle?
How many RADIUS and TACACS+ clients will connect, and could that number justify Advance/Carrier licensing?
Which users need mobile tokens, hardware tokens, FIDO or SMS, and are any token licenses already owned?
Will identity be collected through AD polling, RADIUS accounting, the FortiClient SSO Mobility Agent or a combination?
Is there an existing certificate authority, or should FortiAuthenticator provide certificate services for selected workloads?
Is a single appliance acceptable, or is an HA pair required because authentication is a critical dependency?
Procurement checklist
How FourTeck can assist with sizing and deployment planning
FourTeck can help turn an identity requirement into a structured bill of materials rather than quoting only the base appliance. The process can include reviewing the number of users and network clients, identifying suitable hardware upgrade licenses, clarifying FortiToken and SSO requirements, checking high-availability needs and documenting the intended integrations. Where installation or configuration support is required, that scope can be separated from the hardware quotation so responsibilities are clear.
For a large migration, it is useful to provide an inventory of existing RADIUS servers, MFA systems, Active Directory domains, LDAP services, certificate authorities, FortiGate appliances, VPN gateways, wireless platforms and applications that will rely on FortiAuthenticator. FourTeck can use that information to identify dependencies that may otherwise be discovered late in the project.
You can also review related FourTeck security products, explore Fortinet solutions for UAE projects, or send the project requirement to FourTeck for quotation coordination.
UAE availability and support guidance
Contact FourTeck to confirm current UAE availability for the FortiAuthenticator 3000F, because supply can depend on model status, quantity, support term, licensing and vendor lead time. The July 2026 Fortinet data sheet continues to list the FAC-3000F while also showing the newer FAC-3000G in the current hardware range. That makes model validation especially important for new projects: a buyer should not assume that an existing 3000F specification is still the preferred option for every fresh deployment.
A quotation should clearly separate the appliance, any user upgrade licenses, tokens, SSO licenses, support services and optional implementation work. Delivery and project coordination can then be discussed after the exact bill of materials is confirmed. Warranty and support entitlement should be stated in the quotation rather than inferred from a generic web listing. FourTeck can assist with current model guidance and regional procurement through its Fortinet UAE information portal.
Dubai, Abu Dhabi, Sharjah and Ajman project coverage
For organisations planning identity infrastructure across Dubai, Abu Dhabi, Sharjah and Ajman, FourTeck can coordinate requirement review and quotation preparation from a single project brief. This is useful when a central FortiAuthenticator pair will serve several sites or when different offices have separate network devices but share common directory, MFA and access policies. Buyers should provide the intended appliance location, branch connectivity, number of users at each site, WAN dependency, high-availability expectations and whether any local installation or configuration work is required. Site coverage does not imply fixed delivery times or automatic onsite service; those items depend on the final scope, schedule and quotation.
GCC Availability
FourTeck can assist organisations planning FortiAuthenticator 3000F projects across GCC markets with requirement review, model and license selection, quotation coordination, configuration scoping and regional deployment planning. A multi-country project should start by confirming where the appliance will be installed, whether authentication will be centralised or distributed, the number of licensed users, RADIUS and TACACS+ client counts, token requirements and the expected support term. These details can materially change the bill of materials.
Availability, licensing, delivery schedules, service visits and vendor lead times can vary between the United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain and Oman. For that reason, a quotation prepared for one market should not automatically be treated as valid for another. Share the destination country, required quantity, license term, deployment location and expected timeline so the regional requirement can be reviewed. FourTeck’s Kuwait technology portal is also available for Kuwait-focused enquiries.
Africa Availability
For African projects, FourTeck can help organisations evaluate whether the FortiAuthenticator 3000F is the correct appliance for their user population and network scale, then coordinate the required user upgrades, tokens, support and implementation scope. Projects in East Africa, West Africa, Southern Africa or Central Africa may have different procurement, shipping, power, licensing and support conditions, so the destination should be part of the requirement from the beginning.
Buyers should provide the destination country, quantity, intended deployment schedule, user count, network access design, local power and rack requirements, installation expectations and any need for remote configuration or knowledge transfer. Availability and fulfilment can depend on the exact model, quantity, vendor lead time, license region, shipping arrangements and local project conditions. FourTeck does not assume local inventory or guaranteed delivery. For regional enquiries, buyers can use the FourTeck Africa technology portal to discuss project requirements.
Related options worth evaluating
FortiAuthenticator 3000G
Fortinet’s newer high-scale hardware model is listed in the July 2026 data sheet with a higher maximum user ceiling. A new project should compare current regional availability, migration considerations and future scale before locking in the 3000F.
FortiAuthenticator 800G
A smaller hardware option may be more economical when the user population is below the 3000F range. Sizing should be based on users, RADIUS clients, certificates, tokens and future growth rather than model name alone.
FortiAuthenticator VM or Cloud
Virtual and hosted alternatives can be useful when organisations prefer software-defined deployment or do not want dedicated identity hardware. Feature and licensing differences should be reviewed against the same authentication requirements.
FortiToken MFA
FortiToken can provide mobile or hardware authentication factors for supported FortiAuthenticator workflows. Token quantities and type must be quoted separately from the base appliance.
Implementation and migration services
For organisations replacing existing RADIUS, MFA or certificate services, a planned migration can include discovery, configuration, pilot testing, phased cutover and documentation rather than treating the project as a simple hardware installation.
Why businesses contact FourTeck for FortiAuthenticator projects
Large identity projects often fail at the procurement stage because the hardware is selected before the authentication design is fully understood. FourTeck focuses on the practical details that affect a usable quotation: exact model, user capacity, upgrade licensing, token type, RADIUS and TACACS+ scale, HA design, support term, required integrations and implementation scope. This helps procurement teams compare proposals on the same basis.
Technical teams can use the same process to clarify responsibilities before deployment. For example, the customer may own Active Directory changes while FourTeck handles appliance configuration, or the customer may want only supply and licensing with no implementation services. Stating those boundaries early reduces assumptions. FourTeck can also coordinate current UAE availability and help buyers compare the 3000F against newer FortiAuthenticator hardware where that comparison is relevant.
What buyers are trying to understand before choosing a high-scale FortiAuthenticator
A buyer researching the FortiAuthenticator 3000F is usually not trying to answer a single product question. The real decision is whether a dedicated identity appliance at this scale fits the organisation’s current authentication architecture and future growth. The most useful starting point is to separate user capacity from authentication complexity. Forty thousand employees do not automatically create the same load in every environment. A user who authenticates once each morning to a wired network generates a different pattern from a user who moves between Wi-Fi, VPN, SaaS applications and privileged administration throughout the day.
The second issue is often the difference between users, tokens and network clients. The FAC-3000F base license supports 40,000 local and remote users, but the appliance also has separate limits for FortiTokens, user groups, certificates and RADIUS clients. Procurement teams should therefore avoid treating “40,000 users” as the only sizing metric. An organisation with fewer users but tens of thousands of branch devices or NAS clients could have a different licensing requirement from an enterprise with a larger user population but a simpler network.
Create an inventory of FortiGate devices, wireless systems, switches, VPN gateways and other RADIUS or TACACS+ clients. This often reveals whether standard client limits are sufficient or whether the Advance/Carrier license deserves consideration.
Identify which users need mobile tokens, hardware tokens, FIDO or SMS. A hardware appliance quotation without the corresponding authentication factors may not represent the real project cost.
A 3000F, 3000G, VM or cloud deployment can solve different operational constraints. Decide whether dedicated hardware, virtual infrastructure or hosted identity better matches the organisation’s resilience and administration model.
Another frequent research question is whether FortiAuthenticator can replace Active Directory. It should generally be thought of as an authentication and identity-services platform that can integrate with Active Directory and LDAP rather than as a direct replacement for all directory functions. Many enterprises keep Active Directory as the authoritative user directory and use FortiAuthenticator to add RADIUS, MFA, SSO, federation and certificate capabilities around it. This arrangement can reduce the need to expose domain controllers directly to every network access device.
Buyers also ask whether FortiAuthenticator is only for Fortinet networks. The platform is designed to integrate strongly with Fortinet products, but it supports standards such as RADIUS, LDAP, SAML, OIDC and X.509 that are also used by third-party systems. Compatibility still has to be checked per application or device. A vendor supporting RADIUS does not guarantee that every desired attribute, accounting function or MFA flow will behave exactly as expected.
For new 2026 projects, model lifecycle is another important consideration. Fortinet’s current data sheet still lists the FAC-3000F and introduces the FAC-3000G as a newer high-scale option with a much higher maximum user ceiling. This does not make the 3000F unsuitable, but it does mean a new buyer should confirm current regional ordering guidance before committing to a multi-year architecture. If the requirement already specifies 3000F because of an installed estate, standardisation policy or approved design, that context should be included in the quotation request.
Finally, buyers often want a simple price. Large authentication appliances are difficult to compare from web prices because advertised figures may be in different currencies, may represent hardware only, and may exclude support, tokens, user upgrades or services. The most useful commercial comparison is a like-for-like bill of materials. Ask every supplier to quote the same appliance quantity, user capacity, support duration, token count, SSO licensing and implementation scope. That produces a procurement comparison that reflects the project rather than an isolated hardware number.
Decision questions that should be answered before approval
Do we need the 3000F if we have fewer than 40,000 users?
Possibly, but user count alone is not enough to justify it. A smaller user population may still have very high RADIUS client numbers, extensive certificate use or demanding HA requirements. In most cases, however, buyers below the 3000F scale should compare smaller hardware, VM or cloud options and select the platform that meets both current and projected capacity.
Should the quotation include FortiTokens?
Yes, if FortiToken-based MFA is part of the intended design. The appliance supports FortiToken workflows, but tokens are separate products. Specify how many users need MFA, the preferred token type and whether existing valid tokens can be reused. This prevents an incomplete hardware-only quote from being mistaken for the total solution.
When is Advance/Carrier licensing relevant?
It becomes relevant when the project requires client scale beyond the standard RADIUS or TACACS+ design. Fortinet lists the Advance/Carrier license for FAC-3000F and FAC-3000G as providing unlimited RADIUS and TACACS+ clients. Confirm the number of network devices and access systems first so the license is purchased for a real requirement.
Can we migrate authentication in one cutover?
A single cutover may be possible in a simple environment, but a phased approach is usually easier to validate. Start with a pilot group or selected applications, verify logs and failover, then move additional systems. The migration plan should include rollback because authentication failure can affect many services at once.
What does FourTeck need to prepare a useful quote?
Provide the exact model request, appliance quantity, present and projected users, RADIUS and TACACS+ client counts, token needs, support term, HA requirement, destination, preferred timeline and required services. If you can also provide an integration list, the quotation can better reflect the actual deployment scope.
Should we compare 3000F and 3000G now?
For a new deployment, yes. Fortinet’s current data sheet includes both models and shows the newer 3000G with a higher upper user limit. The right choice depends on current availability, regional ordering guidance, lifecycle plans, migration requirements and budget. FourTeck can help ensure the comparison is based on equivalent licensing and support.
Frequently asked questions
What is the FAC-3000F used for?
The FAC-3000F is used to centralise enterprise identity and authentication services, including RADIUS, TACACS+, MFA, Fortinet Single Sign-On, certificate management, guest access, SAML/OIDC federation and integration with directory services.
How many users does FortiAuthenticator 3000F support?
The base license supports up to 40,000 local and remote users. Fortinet documents an upper limit of 240,000 users when the appropriate FortiAuthenticator hardware upgrade licenses are added.
Does the FortiAuthenticator 3000F include FortiToken licenses?
No. FortiToken hardware and software tokens are separate products. The required token type and quantity should be included in the bill of materials when MFA is part of the deployment.
Can FAC-3000F integrate with Active Directory and LDAP?
Yes. FortiAuthenticator supports integration with Active Directory and LDAP identity sources. Connectivity, service accounts, group mapping, DNS, time synchronisation and any certificate requirements should be validated during design.
Does FortiAuthenticator 3000F support high availability?
Yes. Fortinet documents Active-Passive HA and Config Sync HA for the appliance platform. A resilient deployment normally requires a second appropriately licensed appliance plus suitable network and power design.
What interfaces and storage are included on FAC-3000F?
The appliance has four 10/100/1000 RJ45 interfaces, two 10GE SFP+ interfaces and two 2 TB SAS drives configured for RAID 1 local storage.
Which licenses can expand FAC-3000F user capacity?
Fortinet lists compatible hardware upgrade licenses in 100-user, 1,000-user, 10,000-user and 100,000-user increments. The required combination depends on the target licensed-user count and should be confirmed in the quotation.
Should a new project compare FortiAuthenticator 3000F with 3000G?
Yes. Fortinet’s current 2026 data sheet lists both models and shows the 3000G as the newer high-scale option with a larger maximum user ceiling. Confirm current regional availability, lifecycle guidance and migration considerations before choosing.
What information is needed for a Dubai or UAE quote?
Provide the appliance quantity, current and projected user count, RADIUS/TACACS+ client count, FortiToken needs, HA requirement, support term, integrations, destination and whether installation or configuration services are required.
Is UAE availability or warranty guaranteed from this page?
No. Current availability, lead time, warranty and support entitlement should be confirmed in the FourTeck quotation because they can depend on model status, quantity, support option, region and vendor policy.
Request a model-checked FortiAuthenticator 3000F quotation
Send FourTeck your target user count, expected growth, number of RADIUS or TACACS+ clients, MFA token requirement, HA preference, existing directory platforms and deployment location. FourTeck can then help validate whether the FAC-3000F is still the right hardware choice, identify required licenses and support, and prepare a clearer bill of materials for procurement review.
For new deployments, include whether you are open to comparing FAC-3000F with FAC-3000G, virtual or cloud alternatives. That allows the recommendation to consider lifecycle and scale rather than matching only a legacy part number.
