Also known as VPNs.

A Virtual Private Network is a software service which protects online privacy by encrypting traffic to and from the user’s computer while hiding their unique identifier, the Internet Protocol address. This means the internet (a public network) effectively becomes an extension of the user’s private (home or office) network, with all data unable to be ‘seen’. VPNs are used as a security measure connecting remote applications or offices, and to access geo-restricted services as the user’s location is obscured.
