The Ultimate Guide to VPNs: Understanding the Basics

A virtual private network (VPN) extends a private network across a public network, enabling users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running on a computing device, e.g., a laptop, desktop, smartphone, or tablet, can therefore benefit from the functionality, security, and management of the private network.

VPNs can be used to access region-restricted websites and services, shield your browsing activity from prying eyes on public Wi-Fi hotspots, and more. Businesses frequently use VPNs to allow employees to securely access the company's intranet while working remotely.

The history of VPNs can be traced back to the 1990s, when they were first developed to allow remote workers to securely access their company's network. In recent years, VPNs have become increasingly popular for personal use, as people become more aware of the importance of online privacy and security.
