PacketFence is a fully supported, trusted open-source network access control (NAC) solution that provides comprehensive device visibility, policy-based access control and compliance enforcement across wired, wireless and IoT network environments. The platform helps organizations control which devices access the network, enforce security policies at connection time and automatically isolate non-compliant or unauthorized endpoints.

No per-device licensing with full source code access and enterprise support.
VLAN Assignment & Segmentation
Dynamic VLAN assignment based on user role, device type and compliance status for automated network segmentation.
Compliance Enforcement
Endpoint health checks verify antivirus status, OS patches, firewall configuration and security requirements before granting access.
IoT Device Security
Specialized profiling and policy enforcement for IoT devices that cannot run traditional NAC agents.
Multi-Vendor Support
Works with network equipment from Cisco, HPE/Aruba, Juniper, Ruckus, Dell and Meraki through standard protocols.
Solution overview
PacketFence provides 802.1X authentication, MAC authentication bypass (MAB), captive portal access, RADIUS-based policy enforcement and VLAN assignment across multi-vendor network infrastructure. The platform integrates with Active Directory, LDAP, SAML and other identity sources for user-based network access decisions.
Device profiling uses DHCP fingerprinting, HTTP user-agent analysis, network behavior analysis and SNMP data to automatically identify and classify all connected devices including IoT endpoints, BYOD devices, printers, medical devices and industrial equipment. Compliance enforcement checks endpoint security posture before granting full network access.
