FortiLink NACis the NAC (Network Access Control) engine built into FortiGate when it manages FortiSwitch devices.
It performs:
Automated device onboarding
Automatically detects new devices connecting to switches.
Uses MAC, vendor, DHCP fingerprinting, or IoT database to classify devices.
No manual VLAN assignment required.
Security posture verification
Works with FortiClient EMS, ZTNA tags, IoT detection.
Applies policies based on:
Device type
User role
Endpoint compliance
IoT vulnerability status
Dynamic VLAN assignment
Automatically moves devices into proper VLANs, quarantine networks, or guest zones.
Integration with LAN Edge & Zero Trust
Uses FortiGate + FortiSwitch + FortiAP to enforce zero-trust access.
This matches the LAN Edge 7.6 Architect explanation of FortiLink NAC.
