What is Virtual Private Network

A virtual private network (VPN) allows the provisioning of private network services for an organization or organizations over a public or shared infrastructure such as the Internet or service provider backbone network. The VPN is a network emulated (the virtual) built on public infrastructure (shared), dedicated to a client (the private) to connect users in locations and to ensure similar conditions of integrity, confidentiality and quality similar with those of a private network.

Software, run on a client computer, that allows it to connect to a remote network and appear as if connected locally.

A security function that uses cryptographic key exchanges and encryption suites to encapsulate and tunnel traffic securely across insecure IP-based networks using TCP (SSL/TLS) or UDP (Internet Protocol Security) methods.

A technology that uses an encrypted connection to add security and privacy to private and public networks.

A virtual private network extends a private network across a public network and enables users to send and receive data across shared or public systems as if their computing devices directly connected to the private network.
