Why create a virtual private network?

Virtual Private Networking (VPN) tunnels enable you to and securely connect computers in two locations without requiring expensive, dedicated point-to-point data connections. With VPN, you use low cost connections to the Internet to create a virtual connection between two branch offices. Unlike a simple, un- encrypted Internet connection, a VPN connection eliminates any significant risk of data being read or altered by outside users as it traverses the Internet.
