The FortiNAC M-550F is a centralized management appliance for multi-site deployments with multiple appliances. Manages up to 50 CA servers. FortiNAC discovers and profiles every device on the network, including the unmanaged ones that cannot run an agent, and enforces what each is permitted to reach.
A management appliance, not a control server; it manages up to 50 CA servers and is only required once a deployment spans multiple control appliances. A single-site deployment does not need it, and buying it early adds a tier to operate for no benefit.
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.
This is not sized on ports at all; it manages up to 50 control servers and is only needed once a deployment spans several. A single site does not need it, and buying it early adds an operational tier for no benefit. The trigger is architectural: when you have more than one control appliance and want one policy view across them, this is what provides it.
What to order alongside the FortiNAC M-550F
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.
