The Falcon Project (Free Application-Level CONnection kit) is an open firewall project with the intention of developing a free, secure and OS-independent firewall system. Falcon consists of three major modules: Falcons’s own proxies (written in Perl); 3rd-party proxies (squid / qmail / BIND8), each modified for chroot environment; and general concepts for OS hardening, chrooting etc.
