PacketFence is a network access control (NAC) system. It is actively maintained and has been deployed in numerous large-scale institutions. It can be used to effectively secure networks, from small to very large heterogeneous networks. PacketFence provides NAC-oriented features such as registration of new network devices, detection of abnormal network activities including from remote snort sensors, isolation of problematic devices, remediation through a captive portal, and registration-based and scheduled vulnerability scans. License: GNU General Public License (GPL) Changes: This release adds support for VLAN isolation, 802.1X, and wireless access points and controllers. It temporarily disables support for ARP-based registration (please consult the May 2008 archive of the packetfence-devel mailing list for more information). There are many bugfixes and general enhancements.
