Virtual Private Networking ( VPN )
Virtual Private Networks
A VPN connects branch offices and remote users by utilizing a public network, such as the Internet, while providing the same security as a private network. Since using a Virtual Private Network involves encrypting data before sending it through the public network and decrypting it once it is received, information is securely protected. Also, because Virtual Private Networks use an existing WAN (Wide Area Network) infrastructure, costs are dramatically reduced and deployment is faster than traditional private networks.
