Virtual private network; a network that connects remote sites or users via the Internet using virtual connections so that devices can communicate as if they were on a private network.
A virtual private network (VPN) is a network that connects remote sites or users via the Internet using virtual connections so that devices can communicate as if they were on a private network. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
