IPFire is a hardened, versatile, state-of-the-art Open Source firewall based on Linux. Its ease of use, high performance in any scenario and extensibility make it usable for everyone.

The primary objective of IPFire is security. Its easy to configure firewall engine and Intrusion Detection System prevent any attackers from breaking into your network. In the default configuration, the network is split into various zones with different security policies such as a LAN and DMZ to manage risks inside the network and have custom configuration for the specific needs of each segment of the network.

But even the firewall needs to protect itself. IPFire is built from scratch and not based on any other distribution. This allows the developers to harden IPFire better than any other server operating system and build all components specifically for use as a firewall.
