OpenVPN

OpenVPN is an open source SSL VPN tool that works in a wide range of configurations, including remote access, site-to-site VPNs, Wi-Fi security, and enterprise-scale remote access solutions with load balancing, failover, and fine-grained access-controls.

According to the OpenVPN website, it's based on SSL, the industry standard for secure communications on the Internet.

"OpenVPN implements OSI layer 2 or 3 secure network extension using the SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or 2-factor authentication, and allows user or group-specific access control policies using firewall rules applied to the VPN virtual interface," the site says. "OpenVPN is not a web application proxy and does not operate through a web browser."
