Sigma VPN is a light-weight VPN solution aimed at providing easy-to-configure and secure VPN tunnels for UNIX systems.

  • Sigma is modular. It is very easy to create new interfaces and encryption/encoding schemes.
  • Sigma is slim. It's just a few hundred lines of pure C.
  • Sigma is easy to configure, allowing you to put settings for multiple tunnels into just one configuration file.
