What Is a VPN?
A VPN, or virtual private network, is a technology that creates an encrypted connection between your device and the internet. A reliable VPN masks your IP address, hides your location, and protects your data from eavesdropping. VPN services differ in protocols, server networks, and privacy policies, but all VPNs share the same goal: improving online privacy and security.
How VPN Works
A VPN service routes your internet traffic through a secure server. When you connect to a VPN server, the VPN app encrypts outgoing traffic before it leaves your device. The VPN server decrypts and forwards requests to websites, then encrypts the responses before sending them back to you. This process prevents ISPs, public Wi-Fi operators, or attackers from easily monitoring your activity.
