Endian Firewall™ is a “turn-key” linux security distribution that turns every system into a fully featured security appliance. The software has been designed with “usability in mind” and is very easy to install, use and manage, without losing its flexibility. The features include a stateful packet inspection firewall, application-level proxies for various protocols (HTTP, POP3, SMTP, SIP) 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 (for a full-featured list see below).
