Overview
Virtual private networks (VPNs) have existed almost as long as the modern Internet. VPN technology was created in 1996 at Microsoft by an employee who developed the peer-to-peer tunneling protocol (PPTP) to establish a more private and secure connection between a computer and the Internet.
The purpose of a VPN is to establish an encrypted tunnel between a device or endpoint (like a laptop, mobile phone, or desktop) and one or more Internet-facing servers. For a business, a VPN ensures that a user can connect to a company's internal private network and securely connect to the public Internet.
