The Falcon Project (the Free Application-Level CONnection) is an open firewall project with the intention of developing a free, secure and OS-independent firewall system. Falcon consists of different modules: Falcons’s own proxies (generic TCP proxy and application-specific proxies), Squid for Web access and caching (modified package for Linux), and qmail for mail communication.
