A Virtual Private Network (VPN) creates a secure, encrypted connection between a user's device and a remote server over the internet. This allows users to transmit data securely, preventing unauthorized parties from intercepting sensitive information such as passwords or credit card numbers. VPNs are commonly used to protect privacy, access region-locked content, and bypass internet censorship. By routing traffic through an encrypted tunnel, VPNs also conceal the user's IP address, adding an extra layer of anonymity. Popular among businesses and individual users alike, VPN technology is a crucial tool for maintaining online security in an increasingly connected world.
