Viscosity is an OpenVPN client for Mac, providing a rich Cocoa user interface for creating, editing, and controlling VPN connections. Viscosity provides a complete OpenVPN solution for Leopard (Mac OS X 10.5) and does not require any additional downloads or software.

With Viscosity and OpenVPN you can securely connect to your home or company network from a remote , protect your network traffic when using public or wireless networks, access websites with country restrictions, and tunnel through restrictive firewalls and proxy servers to give your computer full Internet access.
