- 50 CA servers
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.
Highlights
- Manages up to 50 CA servers
- Agentless discovery and profiling of unmanaged devices
- Multi-vendor — works with the switching you already own
- Dynamic VLAN and ACL enforcement at the access layer
Typical deployments
- Multi-site deployments running several control servers
- National estates with regional NAC appliances
- Service providers managing NAC for multiple customers
