VPN (Virtual Private Network) allows you to securely connect to the Internet, a public network (such as free Wi-Fi at the airport), or any other area.
VPN stands for Virtual Private Network. As the name suggests, this is a virtual network, created over the Internet or a public network between two or more physical networks (or devices) to create an extended private network.
