pfsense is a FreeBSD router OS that can be installed on embedded systems or PC/Server PC hardware. Its a free, open source customized distrobased off of FreeBSD 7 specifically tailored for use as a firewall and router. Its one of the most secure router OS’s out there. Large corporation and universities use this router OS because of thestability, failover, and stacking capabilities. If you have heard of M0n0wall or IPCop then you should have an idea what pfsense is.
