FortiAuthenticator RADIUS Server in Dubai, UAE
FortiAuthenticator can act as a central RADIUS authentication, authorisation and accounting platform for wired access, corporate wireless, VPN connectivity and supported network administration use cases. The value for a business is not simply replacing one password database with another. It is creating a controlled point where identity sources, authentication methods, network access policies and accounting information can be coordinated consistently.

Direct answer: what is FortiAuthenticator RADIUS Server?
FortiAuthenticator is an identity and access management platform that includes a built-in RADIUS service. When deployed as the RADIUS server, it receives authentication requests from network access servers such as firewalls, wireless controllers, switches, VPN gateways or other compatible devices, evaluates the request against configured policies and identity sources, and can return access decisions and attributes. Businesses should consider it when they want central control over network authentication instead of maintaining separate credentials on each device. Before proceeding, confirm the FortiAuthenticator form factor, licensed user capacity, number of RADIUS clients, directory integration, EAP or MFA method, certificate needs, redundancy requirements and compatibility of the requesting network equipment.
What the RADIUS service does
RADIUS gives network devices a standard method to ask a central server whether a user or device should be allowed access and, when appropriate, what attributes should be returned. In a FortiAuthenticator deployment this can support corporate Wi-Fi authentication, 802.1X wired access, VPN authentication, administrative login to supported devices and other RADIUS-aware services. Authentication verifies identity, authorization helps determine what that identity is allowed to do, and accounting can record session-related information when the surrounding equipment sends accounting messages.
The important design decision is where policy authority should live. FortiAuthenticator can maintain local users, integrate with remote directory services and apply RADIUS policies. That allows an organisation to keep identity data and access logic central while network devices remain focused on connectivity and enforcement.
Who should consider it
FortiAuthenticator RADIUS functionality is relevant to businesses that have reached the point where local passwords on firewalls, switches, wireless systems and remote-access gateways are difficult to govern. It can suit offices with enterprise Wi-Fi, multi-floor campuses using 802.1X, organisations with large remote-access populations, education environments, healthcare facilities, hospitality networks, retailers with many branches, industrial sites and enterprises with mixed Fortinet and third-party infrastructure.
It may be unnecessarily complex for a very small environment with only a few accounts and no need for centralised identity. It also should not be selected solely because RADIUS is supported. Buyers should consider user volume, client-device count, availability requirements, directory architecture, certificate operations, MFA expectations and the internal skills available to administer policy safely.
Business problems a central RADIUS design can address
Scattered administrator accounts
When every switch, firewall and wireless device has different local administrator credentials, offboarding and password policy enforcement become difficult. A RADIUS-based administration design can centralise supported device logins, subject to the capabilities of each network platform.
Inconsistent Wi-Fi authentication
Enterprise WLANs often need users or managed devices to authenticate before joining. FortiAuthenticator can participate as the RADIUS server for 802.1X and can integrate with identity stores or certificate-based authentication methods.
Remote-access identity control
VPN access should reflect current identity and policy rather than long-lived device-local accounts. RADIUS allows a compatible VPN gateway to delegate authentication decisions to FortiAuthenticator, with MFA available where the chosen method and licensing support it.
Policy tied to identity
Dynamic VLAN assignment and Change of Authorization can support identity-aware network access when the access equipment and policy design are compatible. These features should be tested carefully before broad deployment because behaviour depends on the complete network path.
Core RADIUS capabilities within FortiAuthenticator
AAA services
FortiAuthenticator can serve as a central RADIUS AAA platform, allowing compatible access devices to submit authentication requests and, where configured, exchange authorization information and accounting records.
802.1X access
The platform supports 802.1X network access use cases for wired and wireless environments. EAP-TLS can be used where certificate-based authentication is selected and certificates, endpoints and supplicants are prepared correctly.
Directory integration
FortiAuthenticator can work with remote LDAP and Active Directory environments as identity sources, helping businesses avoid creating an unrelated credential store purely for network access.
MFA options
Multi-factor authentication can be added to selected workflows using supported FortiToken, OTP, certificate or passwordless methods. Token, SMS and related entitlements can have separate licensing or subscription requirements.
Fit matrix: where FortiAuthenticator RADIUS makes sense
| Requirement | Suitable when | Confirm before ordering |
|---|---|---|
| Corporate Wi-Fi | You need individual user or device authentication rather than one shared wireless password. | WLAN RADIUS support, chosen EAP method, certificate or credential source, failover behaviour. |
| Wired 802.1X | Switch ports should authenticate users or devices before granting production network access. | Switch feature support, endpoint supplicant configuration, fallback design for phones, printers and IoT. |
| VPN authentication | A compatible VPN concentrator should use central identities and optionally MFA. | Authentication flow, token requirements, user groups, timeout values and recovery process. |
| Network admin login | Supported network devices can delegate administrator authentication to RADIUS. | Vendor-specific attributes, local break-glass accounts and role mapping. |
| Large distributed estate | Many access devices need one consistent authentication service. | Licensed user limit, RADIUS client limit, WAN dependencies, HA or load balancing and carrier license applicability. |
Verified platform information for RADIUS buyers

| Important note | Do not size the solution from user count alone. Include RADIUS client count, policy objects, identity sources, tokens, certificates, resilience and growth. |
Licensing, capacity and compatibility dependencies
FortiAuthenticator is licensed and sized differently depending on whether the deployment uses hardware, virtual-machine licensing or a cloud subscription. Current ordering information shows hardware models with base user limits and optional user upgrades, while VM licensing starts with a base user entitlement that can be expanded. RADIUS client limits are also related to licensed capacity, so an organisation with a modest number of users but hundreds or thousands of network devices should not assume that user count alone determines the correct license.
MFA components need separate attention. FortiToken Mobile, hardware tokens, SMS delivery and other authentication methods can have their own purchase or entitlement rules. EAP-TLS requires certificates and a working trust model, and the endpoint supplicant must be configured to use the intended certificate and validate the authentication server correctly. Dynamic VLAN and Change of Authorization rely on the access device understanding and enforcing the returned RADIUS attributes.
For third-party network equipment, confirm RADIUS standards support and any vendor-specific attributes before the project is approved. A laboratory or pilot phase is particularly useful when role mapping, VLAN changes, certificate authentication or administrative authorization must behave consistently across several device vendors.
A practical purchase and deployment journey
Map authentication flows
List every system that will send RADIUS requests: firewalls, VPN gateways, wireless controllers, access points, switches or administration interfaces. Document where the user record resides and what authentication method is expected.
Size users and clients
Count active identities, service accounts where relevant, devices that become licensed identities in certificate scenarios, and the number of RADIUS clients. Add reasonable growth rather than sizing only for today’s minimum.
Select deployment form
Choose appliance, VM or cloud according to infrastructure policy, scale, resilience, operational ownership and network latency. Evaluate HA separately from basic authentication capability.
Build and test policies
Configure clients, identity sources, authentication policies, certificates or tokens, then test success, failure, timeout and failover conditions. Pilot with a controlled user group before wide migration.
Identity integration without rebuilding every account
A major reason to deploy FortiAuthenticator as a RADIUS server is to avoid managing an isolated user database for every network service. The platform can integrate with external identity stores such as Active Directory and LDAP, allowing the RADIUS policy to make decisions using existing organisational identities and groups. This is useful when employees change departments, leave the company or need access based on current directory membership.
Directory integration still needs careful design. Decide whether FortiAuthenticator will query remote identities, synchronise selected users, maintain local emergency accounts or combine several sources. Group names and nested membership can influence policy outcomes, while connectivity to domain controllers or LDAP services becomes part of the authentication dependency chain. For high-availability environments, ensure identity-source reachability is resilient as well as the RADIUS server itself.
Service accounts and non-human identities should be reviewed separately. Some devices cannot use an interactive second factor, and some legacy systems have limited RADIUS or EAP support. The design should preserve an appropriate fallback without turning that fallback into an uncontrolled bypass.
802.1X and certificate-based access for wired and wireless networks
FortiAuthenticator can act as the RADIUS server in an 802.1X architecture. In a typical design, an endpoint runs a supplicant, the switch or wireless infrastructure acts as the authenticator or network access server, and FortiAuthenticator evaluates the request. The actual access experience depends on the selected EAP method, endpoint configuration, certificates, directory records, network-device policy and what happens when authentication fails.
EAP-TLS is attractive where organisations want certificate-based device or user authentication instead of relying only on passwords. It also introduces operational work: certificates must be enrolled, trusted, renewed and revoked; endpoints must trust the correct CA; and administrators need a recovery path when a certificate expires or a managed device is reimaged. FortiAuthenticator includes certificate-management capabilities that can participate in such a design, but PKI scope should be planned as a project of its own rather than treated as a checkbox.
Not every endpoint can perform 802.1X in the same way. Printers, phones, cameras, sensors and other IoT devices may require MAC Authentication Bypass or a separate access method. Those exceptions should be placed in restricted segments where practical and reviewed periodically so an old exception does not become permanent unrestricted access.
MFA and stronger verification for VPN and administrator access
RADIUS is often selected because the business wants more than a central password check. FortiAuthenticator supports multi-factor authentication options across the wider platform, including FortiToken-based methods, OTP channels and certificate or passwordless approaches. In a VPN workflow, the compatible gateway can send authentication to FortiAuthenticator so policy and a second factor can be applied without maintaining the entire identity process on the VPN device itself.
The correct factor depends on user experience, network reachability, risk and recovery requirements. Push approval is convenient but depends on mobile connectivity and service availability. Hardware tokens can suit users who cannot use a phone. Email OTP is simple but ties security to the email account. SMS can involve separate credits or gateway configuration. Certificates can reduce repetitive prompts but shift the burden to certificate lifecycle management.
Administrator access deserves especially careful handling. Keep secure local break-glass credentials for emergencies, protect them with organisational controls, and test what happens when RADIUS is unavailable. Centralisation should reduce routine local accounts without creating a single outage path that prevents administrators from recovering the network.
Resilience, latency and operational continuity
Authentication is a foundational service. If every staff Wi-Fi connection, switch port and VPN login depends on RADIUS, an unavailable authentication path can become a business outage even when the rest of the network is healthy. FortiAuthenticator appliance and VM deployments support high-availability options, but resilience should be designed end to end. That means considering the FortiAuthenticator nodes, the identity directory, DNS, NTP, certificate services, network paths and the client-device configuration that determines which RADIUS server is contacted.
For distributed branches, latency and WAN dependence matter. A remote office whose wireless access requires a RADIUS round trip to a distant data centre should be tested under real WAN conditions. Some network devices support primary and secondary RADIUS servers with configurable timeouts and retries. Those settings need to align with failover goals; an excessively long timeout can make users experience repeated delays even though a secondary server is available.
Accounting traffic can add operational value for session visibility, but it also adds message volume and storage considerations. Define how long authentication and accounting logs need to be retained, whether logs are forwarded to a SIEM, and which events the operations team will actually monitor. Resilience is not only keeping the service online; it is ensuring support teams can understand why a login succeeded or failed.
Ideal business environments and common use cases
Corporate offices
Centralise staff Wi-Fi, VPN and network administration authentication while using existing directory groups for policy. Suitable where IT wants fewer local accounts and a controlled onboarding or offboarding process.
Education and campuses
Support 802.1X access across many switches or wireless access points and differentiate staff, students and managed devices. Guest access should remain a separate policy and onboarding flow.
Healthcare and professional services
Use identity-aware authentication for users who need controlled access to sensitive systems, while maintaining careful exception handling for specialist devices that may not support enterprise authentication.
Retail and branch networks
Provide a consistent authentication service across distributed locations, subject to WAN resilience and local failover planning. Central policy can reduce manual account differences between branches.
Data centres and infrastructure teams
Centralise administrative authentication to compatible network devices, keeping break-glass access and vendor-specific authorization requirements documented.
Hybrid environments
Combine traditional RADIUS network access with the broader FortiAuthenticator identity capabilities used for SSO, certificates and MFA, while avoiding unnecessary coupling between unrelated authentication flows.
Integration and operational considerations
A successful RADIUS deployment is rarely just a server installation. Every requesting device needs a client definition, shared secret or other supported trust setup, source IP that matches the configured client, reachable UDP or supported transport path, and compatible authentication settings. Firewalls and access controls between the device and FortiAuthenticator must allow the required traffic. Time synchronisation is also important, especially where certificates, OTP methods or log correlation are involved.
If the business uses multiple network vendors, document which RADIUS attributes each one expects. A policy that works for a FortiGate VPN may not be suitable for a third-party wireless controller or a switch administrator role. Keep policies narrow enough that a change for one system does not unexpectedly affect another. Naming standards for RADIUS clients, groups and policies make troubleshooting faster when the estate grows.
Monitoring should answer practical questions: Which server processed the request? Which policy matched? Was the user found? Did the directory reject the password? Did MFA time out? Was a certificate untrusted? Did the client send the expected attribute? The operational runbook should include these checks so help-desk teams can separate identity problems from Wi-Fi, VPN or endpoint issues.
Questions buyers should resolve before requesting a quote
How many identities are in scope?
Count employees, contractors, service users and any device or computer identities that may consume licensed capacity in the selected authentication design. Include projected growth and remote users.
How many RADIUS clients are needed?
A client is typically a network access server such as a firewall, switch, wireless controller or other device that sends requests. A distributed estate can have many clients even when user count is moderate.
Which authentication method is required?
Password, EAP-TLS, token-based MFA, push, OTP and other methods have different user-experience and dependency requirements. Select methods per use case rather than forcing one method everywhere.
What happens during an outage?
Define RADIUS server redundancy, directory redundancy, local emergency accounts, secondary-server timeouts and the business impact if authentication becomes unavailable.

How FourTeck can help with sizing and deployment planning
FourTeck can help translate an authentication requirement into a clearer bill of materials and project scope. That can start with a review of user count, network access servers, FortiGate or third-party devices, wireless architecture, directory sources and existing authentication methods. The objective is to identify whether the requirement is primarily VPN authentication, enterprise Wi-Fi, wired 802.1X, device administration, MFA, certificate authentication or a combination of these.
Sizing can then include the FortiAuthenticator deployment type, licensed users, RADIUS-client count and growth. Where MFA is required, token type, quantity and delivery method should be identified separately. Where EAP-TLS is required, certificate authority design, endpoint enrollment and renewal procedures should be included in the project conversation. If availability is important, the quotation can also consider HA and the infrastructure needed to host redundant virtual appliances or connect redundant hardware.
Configuration scope should be explicit. A product quote does not automatically include directory integration, network-device configuration, certificate deployment, policy migration, endpoint supplicant work, testing or documentation. Businesses can ask FourTeck to include these activities where relevant. For complex environments, a staged pilot usually provides better confidence than moving every branch, switch or user group at once.
UAE availability and support guidance
FortiAuthenticator availability in the UAE can vary by model, license type, user capacity, quantity and vendor lead time. Current portfolios can include hardware appliances, virtual-machine licensing and cloud-delivered options, but the most suitable choice depends on how the organisation intends to operate and support the service. Contact FourTeck to confirm the exact model, subscription or license that matches the required user and RADIUS-client capacity.
For a UAE project, share the deployment location, identity architecture, required quantity, target authentication use cases and expected project timeline. Delivery and project coordination can be discussed once the scope is clear. If installation, directory integration, policy configuration, testing or documentation is required, include those requirements in the quotation request rather than assuming they are part of the product supply. This helps separate product availability from the engineering work needed to put the RADIUS service into production safely.
Dubai, Abu Dhabi, Sharjah and Ajman project coordination
Organisations operating across Dubai, Abu Dhabi, Sharjah and Ajman can use the same requirement framework even when offices differ in size. Start by identifying whether each location authenticates locally or depends on a central FortiAuthenticator instance, then assess WAN resiliency, RADIUS timeout settings and local recovery options. Multi-site organisations should also standardise client naming, shared-secret handling, policy ownership and change control. FourTeck can help coordinate product selection and deployment discussions across these UAE locations, subject to the exact project scope, access arrangements and technical requirements. Service scheduling, installation activities and delivery timing should be confirmed in the final quotation rather than assumed in advance.
GCC Availability
For organisations planning FortiAuthenticator RADIUS deployments across the GCC, procurement should be coordinated around a common technical standard while still allowing for country-specific ordering and project conditions. FourTeck can assist with requirement review, hardware or VM selection, user and RADIUS-client sizing, license planning, MFA options, configuration scope and rollout discussions for projects involving the United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain and Oman. Availability, vendor lead times, licensing, delivery schedules and service visits can vary by destination, model, quantity and project scope. Before requesting a regional quotation, provide the destination country for each site, required FortiAuthenticator form factor, licensed user count, estimated RADIUS clients, token requirements, deployment location and target timeline. If installation or configuration is expected, describe whether the work includes directory integration, wireless or switch changes, VPN authentication, certificate services, HA design or migration from an existing RADIUS platform. This information allows the commercial and technical scope to be separated clearly and reduces the risk of ordering the wrong capacity or assuming a service is included when it is not.
Africa Availability
Businesses planning FortiAuthenticator authentication projects in Africa can use FourTeck for regional procurement and technical requirement discussions, including projects in East Africa and markets such as Kenya and Uganda where centralised identity is being considered for offices, campuses, branches or data-centre environments. The right RADIUS design depends on more than the server license. Buyers should share the destination country, number of users, number of access devices, directory source, VPN or 802.1X requirements, token needs, preferred deployment model and any local installation or support expectations. Product and license availability may differ according to destination, quantity, vendor lead time, power or infrastructure requirements, subscription region and local project conditions. Shipping arrangements, on-site work and support coverage should therefore be confirmed for each requirement rather than assumed. FourTeck can also help review whether a central regional deployment or multiple local authentication nodes make more operational sense, particularly where WAN quality, branch resilience or regulatory requirements influence where identity services should run. For Africa-specific discussions, buyers can also review FourTeck Africa technology services or FourTeck Kenya project guidance.

Why businesses contact FourTeck for FortiAuthenticator projects
The difficult part of a RADIUS project is usually not proving that FortiAuthenticator supports RADIUS. The difficult part is choosing the correct deployment, capacity and authentication design for the organisation that will depend on it. FourTeck can help clarify the requirement before a quote is requested, including how many identities and RADIUS clients need to be supported, which network devices are involved, where identity data resides, whether MFA or certificates are required and what level of redundancy is expected.
This planning is particularly useful when several teams own different parts of the project. The network team may manage switches and wireless systems, the security team may own MFA, the infrastructure team may operate Active Directory, and procurement may need a single bill of materials. A structured review can make dependencies visible before equipment or licenses are purchased.
FourTeck can also discuss quotation coordination, installation scope, configuration work, migration planning and regional availability. The final deliverables should be defined in the quotation so buyers know whether they are purchasing a product license, an engineered deployment, ongoing support, or a combination of these items.
How buyers are evaluating central RADIUS authentication today
When business buyers investigate FortiAuthenticator as a RADIUS server, the first question is often whether it can replace a mixture of Windows NPS, local firewall accounts, wireless-specific user stores and older authentication servers. The practical answer depends on what each existing system is doing. FortiAuthenticator can provide central RADIUS AAA and integrate with directory services, but a migration should inventory every RADIUS client, policy rule, vendor-specific attribute and exception before the old service is retired. A simple password-authentication workflow is easier to move than a mature 802.1X environment with dynamic VLANs, certificate authentication and many device classes.
Can FortiAuthenticator replace Windows NPS?
It can perform the RADIUS server role for many network-authentication use cases, but replacement is a project rather than a one-click conversion. Compare policies, EAP methods, certificates, group conditions, accounting, device-specific attributes and failover behaviour. Keep NPS available during the pilot until the new service has been tested with every important device type.
Does it work only with Fortinet equipment?
No. FortiAuthenticator supports standard RADIUS and can operate in heterogeneous environments. Third-party compatibility still depends on the client device’s RADIUS implementation, supported authentication methods and attributes. For mixed-vendor estates, a proof of concept is sensible before broad rollout.
Another common buying question is whether hardware is necessary. FortiAuthenticator is available in physical, virtual and cloud-delivered forms, so the answer depends on infrastructure policy, scale and operational preference. Hardware can provide an appliance-based deployment with defined system capacity. A virtual machine can fit organisations standardising on VMware, Hyper-V or supported public-cloud infrastructure, subject to the current Fortinet VM requirements and licensing. A cloud-delivered option can reduce on-premises platform ownership, but buyers should confirm whether its feature set, regional requirements and dependency on external connectivity fit the intended RADIUS use case.
Buyers also search for FortiAuthenticator user limits because licensing can materially change the design. Current ordering information lists base and upgrade capacities for hardware families and scalable user licensing for VM deployments. The key point is that user licensing can influence maximum object and client counts. A network with 700 users and a very large number of RADIUS clients should therefore be sized differently from a network with 700 users and only three authentication devices. Ask for sizing that includes both identities and network access servers.
Buyer insight: count authentication clients early
Organisations often count only employees because user licenses are easy to understand. In RADIUS projects, the number of client devices can also matter. A campus with hundreds of access devices, a managed service environment or a large distributed enterprise should provide an accurate NAS-device count before a license is selected. Current Fortinet ordering information includes an advanced/carrier option for specific deployments where very large RADIUS or TACACS client counts are required; applicability must be confirmed for the chosen platform and model.
MFA is another area where buyers can make an incorrect assumption. RADIUS support does not mean every second-factor method is automatically included. FortiAuthenticator supports several MFA methods, but FortiToken products, SMS usage and related services can require additional purchases. Decide which user groups actually need MFA. For example, it may be essential for VPN and privileged administrators while certificate-based 802.1X handles managed endpoints. Matching the factor to the workflow can reduce friction and avoid buying token capacity for users who never need that factor.
For wireless authentication, buyers frequently ask whether FortiAuthenticator can use Active Directory. The platform can integrate with LDAP and Active Directory identity sources, allowing enterprise network access to rely on existing directory identities. The more important question is how credentials or certificates are validated and which group data should determine access. If the goal is certificate-based corporate Wi-Fi, plan certificate enrolment and endpoint configuration at the same time as the RADIUS server. If the goal is password-based EAP, confirm the authentication method supported by the wireless client and the security policy.
Quotations become more accurate when buyers provide a small architecture summary rather than only asking for a FortiAuthenticator price. Include approximate users, RADIUS clients, existing directory, network vendors, VPN users, wireless and wired 802.1X scope, desired MFA method, certificate requirements and whether redundancy is required. This allows FourTeck to discuss the correct appliance or VM sizing, identify obvious license dependencies and separate product cost from implementation services. Pricing visible on international reseller pages can be useful only as a rough market reference; actual UAE pricing depends on model, support, licenses, quantity and current commercial terms.
Finally, buyers should plan the operating model. Decide who will create RADIUS clients, approve policy changes, manage tokens, maintain certificates, troubleshoot failed requests and review logs. Central authentication can reduce duplicated administration, but it also becomes an important shared service. Documenting ownership, backup procedures and emergency access is as important as selecting the product itself.
Questions to answer before you shortlist the final design
Should we choose an appliance or a virtual FortiAuthenticator?
Choose based on operational ownership, capacity, infrastructure standards and resilience rather than assuming one form is universally better. Hardware provides a dedicated appliance with model-specific capacities. VM deployment can align with an existing virtualisation or cloud strategy and can scale through licensing within supported limits. Confirm resource requirements, hypervisor or cloud support, backup procedures and HA licensing before deciding.
Can the same server authenticate Wi-Fi, VPN and administrators?
Yes, these are all common RADIUS use cases, but they should normally use separate client definitions and well-scoped policies. The authentication method, group conditions and returned attributes can differ. Treating all requests as one generic policy can create difficult troubleshooting and unintended access. Separate policies also make later changes safer.
How do we avoid locking administrators out if RADIUS fails?
Maintain controlled local break-glass accounts on critical network devices and test them under an approved procedure. Configure secondary RADIUS servers where supported, use sensible retry and timeout values, and document the recovery process. Central authentication should reduce routine local credentials, not remove every emergency access path.
What information is needed for a reliable quotation?
Provide the deployment type preference, total users, expected growth, RADIUS client count, identity source, network-device brands, VPN population, 802.1X scope, MFA method, token quantity, certificate needs, HA requirements and implementation scope. Without these details a quote can price the wrong capacity or omit required components.
Do all endpoints need certificates for 802.1X?
Not necessarily. 802.1X supports multiple EAP approaches, and certificate-based EAP-TLS is one strong option. The choice should reflect endpoint management, security policy and user experience. If certificates are selected, plan enrollment, trusted CA distribution, renewal, revocation and support for devices that cannot use the same method.
When should we run a pilot?
Run a pilot whenever the environment uses several network vendors, dynamic VLANs, Change of Authorization, EAP-TLS, MFA, legacy endpoints or critical administrator authentication. A small pilot validates the policy and reveals client-specific behaviour before large groups of users become dependent on the new service.
Frequently asked questions
Is FortiAuthenticator a RADIUS server?
Yes. FortiAuthenticator includes a built-in RADIUS service and can provide authentication, authorization and accounting for compatible network access devices. It also provides other identity services, so RADIUS is one part of the wider platform.
Can FortiAuthenticator use Active Directory for RADIUS authentication?
FortiAuthenticator can integrate with remote identity sources including Active Directory and LDAP. The exact user flow depends on whether users are queried remotely, synchronised, grouped or combined with other authentication factors.
Does it support 802.1X?
Yes. FortiAuthenticator supports 802.1X RADIUS authentication for wired and wireless access. The switch or wireless system, endpoint supplicant and chosen EAP method must also be configured correctly.
Can it use EAP-TLS certificates?
FortiAuthenticator supports EAP-TLS and includes certificate-management capabilities. Certificate authority trust, endpoint enrollment, renewal and revocation need to be planned as part of the deployment.
Can FortiAuthenticator provide MFA for VPN access?
It can support MFA in VPN authentication workflows with compatible gateways and supported factors. FortiToken, SMS or other methods may require separate licensing, credits or services.
How many RADIUS clients can FortiAuthenticator support?
The limit depends on model and licensed user capacity. Current ordering information relates authentication-client maximums to the user license and also lists model-specific limits. Provide both user and RADIUS-client counts when requesting sizing.
Does FortiAuthenticator work with third-party switches and wireless systems?
It uses standard RADIUS and can work with third-party RADIUS clients, but authentication methods and vendor-specific attributes vary. Confirm compatibility and test important policy functions before production migration.
Is high availability available?
FortiAuthenticator appliance and VM deployments support documented HA options. Licensing, topology and current software-version requirements should be confirmed for the intended design.
What should be included in a FortiAuthenticator quote request?
Include deployment type, users, RADIUS clients, identity source, network devices, VPN and 802.1X scope, MFA method, token quantity, certificate needs, HA requirements, project location and implementation services.
How do I confirm UAE availability and pricing?
