What is VPN? How It Works, Types of VPN

The history of Virtual Private Networks (VPNs) dates back to the late 1980s and early 1990s. The earliest form of VPNs were called "Dial-up Networking" and were used primarily by businesses to allow employees to access the company's internal network remotely. These early VPNs used the Point-to-Point Tunneling Protocol (PPTP) to create a secure connection between the employee's computer and the company's internal network. In the mid-1990s, the Internet became more widely available and the need for VPNs began to expand beyond just remote access. The Layer 2 Tunneling Protocol (L2TP) was developed to provide a more secure and reliable VPN connection. L2TP was later combined with the Internet Protocol Security (IPSec) protocol to create the L2TP/IPSec VPN protocol, which is still widely used today. In the early 2000s, the OpenVPN protocol was introduced as an open-source alternative to proprietary VPN protocols. OpenVPN is a highly configurable and secure VPN protocol
