FortiNAC

Why do you need FortiNAC?

A corporate network rarely ends where its documentation ends. IoT, BYOD, OT/ICS, and shadow IT create blind spots. Without NAC, every device gains network access without identity verification and compliance.

FortiNAC is a Network Access Control platform with 21 profiling methods for every device on the network. Zero Trust for devices, automatic segmentation, and native Security Fabric integration ensure complete access control.

How does it work?

Device Profiling

21 methods to identify every device:

• Agentless discovery - passive and active
• MAC address, DHCP fingerprinting
• TCP/IP stack analysis
• HTTP user-agent
• NMAP scanning
• Vendor OUI matching

Zero Trust for Devices

Continuous verification:

• Device authentication before access
• Compliance checking (AV, patching, encryption)
• Continuous monitoring
• Automatic quarantine
• Risk-based access

Microsegmentation

Dynamic network segmentation:

• Policy-based VLAN assignment
• Role-based access control
• Dynamic segmentation rules
• East-west traffic control
• Least privilege networking

FAQ

How does FortiNAC differ from 802.1X? 802.1X is an authentication protocol. FortiNAC is a full NAC platform with device profiling, segmentation, automated response.

How many profiling methods does FortiNAC offer? 21 methods - from passive MAC lookup through active scanning to behavioral analysis.

Does it work with agentless IoT devices? Yes. Agentless profiling for IoT, OT, medical devices. No software required on device.

How does integration with FortiGate work? Security Fabric - FortiNAC can instruct FortiGate for quarantine, policy change, VLAN assignment.

Does FortiNAC support multi-vendor environments? Yes. 170+ vendors - Cisco, HP, Juniper, Aruba, and others. API/CLI/SNMP integration.

What is microsegmentation? Dynamic device assignment to VLANs/segments based on identity, role, compliance.

How does guest/BYOD management work? Self-registration portal, sponsor approval, device profiling, compliance check, time-limited access.

Does FortiNAC detect rogue devices? Yes. Continuous monitoring, new device alerts, unauthorized device quarantine.

How does automated response work? Triggers from Security Fabric or custom rules - quarantine, VLAN change, block, alert.

How does support work? Fortinet 24/7 TAC. nFlo as partner offers NAC deployment and multi-vendor integration.
