The FortiAuthenticator 800F provides single sign-on, RADIUS and LDAP authentication, certificate authority services, guest management and 802.1X for wired and wireless access. It supports 8,000 / 800 local and remote users, 2,666 NAS devices and 16,000 FortiTokens.
8,000 local users, 2,666 NAS devices and 16,000 FortiTokens, with fibre uplinks and dual 2 TB storage. The five-fold NAS increase over the 300F is usually the reason to step up; it is what makes a multi-building campus workable without a second appliance.
How to work out whether it fits
The arithmetic a datasheet leaves out. If any of it does not match your situation, that is worth a call rather than a guess.
The five-fold NAS increase over the 300F is what you are buying, and it is what makes a multi-building campus workable on one appliance. Size it by walking the wiring closets rather than the org chart. Also plan certificate lifecycle here: if you are issuing machine certificates for EAP-TLS, the renewal load is continuous and invisible until it isn't, and it belongs in the sizing conversation.
What to order alongside the FortiAuthenticator 800F
The published threat protection figure for this model is measured with IPS, application control and malware protection all running. Those arrive as a FortiGuard subscription, so the bundle you choose decides whether the hardware can reach the number you sized it on. Every bundle already includes FortiCare Premium 24x7 support.
| Bundle | What it adds | 1 yearlist price | 3 yearslist price | 5 yearslist price |
|---|---|---|---|---|
| Enterprise ProtectionENT | The broadest bundle. Everything in UTP, plus the services that cover data, SaaS posture and attack-surface visibility, plus inline zero-day malware prevention. | on quote | on quote | on quote |
| Unified Threat ProtectionUTP | The traditional mid-tier: perimeter defence covering network, file, web and email threats. Everything most sites actually switch on. | on quote | on quote | on quote |
| Advanced Threat ProtectionATP | The narrow bundle: IPS and the full malware stack including cloud sandboxing, without the web and email filtering layers. | on quote | on quote | on quote |
These are Fortinet list prices. You will not pay them.
Every quote we write is discounted from list, and how far below depends on quantity, term and whether we register the deal with Fortinet. Longer terms also price better per year, which is why three and five year bundles are usually the better buy on a device you intend to keep through a refresh cycle. Part numbers follow Fortinet’s standard bundled convention; not every model carries every combination, so we confirm the exact orderable SKU before anything is placed.
