What is a VPN?

A Virtual Private Network (VPN) is a service that encrypts your internet connection, making your online activities more secure and private. It hides your IP address by routing your traffic through a remote server, ensuring anonymity and data protection. VPNs are widely used to bypass geo-restrictions, enhance security, and maintain privacy online.

How Does a VPN Work?

When you connect to a VPN, your internet traffic is encrypted and routed through a secure tunnel to a remote server. This server assigns you a new IP address, masking your real location. As a result, websites and online services see the VPN’s IP address instead of yours. VPNs use protocols like OpenVPN, WireGuard, and IKEv2/IPSec to establish secure connections, ensuring data integrity and confidentiality.
