VPN connectivity overview, showing intranet site-to-site and remote-work configurations used together From a user perspective, the resources available within the private network can be accessed remotely. A VPN available from the public Internet can provide some of the benefits of a wide area network (WAN). Ī VPN is created by establishing a virtual point-to-point connection through the use of tunneling protocols over existing networks. Encryption is common, although not an inherent part of a VPN connection. VPNs are also used to bypass internet censorship.
The benefits of a VPN include security, reduced costs for dedicated communication lines, and greater flexibility for remote workers. A VPN can extend a private network (one that disallows or restricts public access), enabling users to send and receive data across public networks as if their devices were directly connected to the private network.
