PacketFence is a fully supported, trusted, Free and Open Source network access control (NAC) solution. Boasting an impressive feature set including a captive-portal for registration and remediation, centralized wired and wireless management, 802.1X support, layer-2 isolation of problematic devices, integration with the Snort IDS and the Nessus vulnerability scanner; PacketFence can be used to effectively secure networks - from small to very large heterogeneous networks.

PacketFence integrates perfectly with wireless networks through a FreeRADIUS module. This allows you to secure your wired and wireless networks the same way using the same user database and using the same captive portal, providing a consistent user experience. Mixing access points (AP) vendors and wireless controllers is supported.

Looking at automatically blocking particular devices on your network? PacketFence is for you. In addition to Snort, Suricata, OpenVAS or Nessus as a source of information, PacketFence can combine the following detection mechanisms to effectively block network access from those unwanted devices :

The access duration to the network can be controlled with configuration parameters. It can either be an absolute date (eg. "Thu Jan 20 20:00:00 EST 2011"), a window (eg. "four weeks from first network access") or as soon as the device becomes inactive. On expiration registered devices become unregistered. With little customization it is also possible to do this on a device category basis. Expiration can also be manually edited on a per-node basis.

Because of the intrusive nature of network access control, PacketFence comes with finely-grained controls when it comes to deployment. As described elsewhere, you can automatically pre-register nodes but you can also control on a per-switch and per-port level wether or not should PacketFence perform its duties. This enables you to deploy at the speed you want, per-switch, per-floor, per-location, etc.
