FreeS/WAN is an open-source software implementation of the IPsec (Internet Protocol Security) protocol suite, which is used to secure Internet Protocol (IP) communications through encryption and authentication. The name "FreeS/WAN" stands for "Free Secure Wide Area Network." Developed in the late 1990s, FreeS/WAN was one of the first IPsec implementations available for Linux, allowing users to create secure virtual private networks (VPNs).
