Raphael Vallazza writes "Endian Firewall is a "turn-key" linux security distribution based on IPCop that turns every system into a full featured security appliance. The software has been designed with "usability in mind" and is very easy to install, use and mange, without loosing its flexibility.
The features include a stateful packet inspection firewall, application-level proxies for variuos protocols (HTTP, POP3, SMTP) with antivirus support, virus and spamfiltering for email traffic (POP and SMTP), content filtering of Web traffic and a "hassle free" VPN solution (based on OpenVPN). The main advantage of Endian Firewall is that it is a pure "Open Source" solution that is commercially supported by Endian, an italian OSS company.
The software is released under GPL License, so far Endian has released just the base Module, but all modules will be soon available for download."
