What is a VPN?
A VPN, which stands for virtual private network, is an encrypted network between one or many machines (clients) and a server. It is “virtual” in the sense that it is not a direct physical or WiFi based network. The machines securely connect over an internet connection and define an entirely new set of internal IP addresses by which they communicate. This provides a private network which cannot be snooped on, even by the client’s internet service provider (ISP). It is one of the best network security mechanisms available.
