What is VPN Software?

VPN software refers to any program that assists the user in creating a Virtual Private Network or accesses a remote location. A Virtual Private Network (VPN) is a type of private connection that uses the Internet to securely transfer data from one computer to another. Generally, VPNs involve a server (main database) and the user's computer (client). VPN software facilitates the use of VPNs by providing the user with encryption, user verification, and other tools that make VPNs easier to manage.
