VPN (Virtual Private Network)

A VPN (Virtual Private Network) is a cybersecurity technology that creates a secure, encrypted connection—known as a "tunnel"—over a public network like the internet. By routing user traffic through a remote server and encrypting all data packets using advanced cryptographic protocols, a VPN shields online activities from interception, eavesdropping, and surveillance. This process also masks the user's true IP address, enhancing anonymity and protecting their digital footprint from tracking.

VPNs are essential for extending private network resources securely to remote employees, partners, and individual users—particularly when accessing public Wi-Fi or unsecured connections. They play a critical role in maintaining data privacy, preventing identity theft and data breaches, and ensuring confidential access to sensitive systems across distributed environments. As a fundamental security control, VPNs remain an indispensable component of any robust network and infrastructure security strategy.
