You are browsing over unsecured public WIFI hotspots or your visiting web service is blocked by local authority. There are thousands of reasons why you need to use secured VPN tunneling. Fortunately, there're number of solutions you can have your VPN for free.

OpenVPN uses OpenSSL TCP/UCP to provide secure and flexible tunneling solution. You can setup your own free VPN servers at home or work places.

Servers can be setup on cloud-based Virtual Private Servers inexpensively or on local devices.
