CogniSec Enterprise Firewall

CogniSec Enterprise Firewall is a project designed to create an entirely open source, feature-rich, enterprise firewall and VPN gateway. Using stateful packet filtering mechanisms and adaptive packet scrubbing preprocessors, CogniSecEFW offers advanced firewalling capabilities not found even in the most expensive commercial offerings. Virtual Private Networks use IPSec with IKE to allow for easy integration into existing enterprise infrastructures, and can provide encrypted gateway-to-gateway and client-to-gateway tunnels.

Built on a minimal, hardened, open source foundation, CogniSecEFW offers host based attack mitigation mechanisms to prevent local compromise and host-based intrusion detection systems to detect attempts at firewall circumvention.

Currently CogniSec-FW is subdivided into two projects, Corporate and Enterprise.
