A VPN (Virtual Private Network) application is a software tool designed to provide users with a secure and private online connection. It works by encrypting the internet traffic between the user's device and the VPN server, effectively masking their IP address and location. This allows users to access the internet through a tunnel of encrypted data, making it difficult for hackers, ISPs, or other third parties to monitor or intercept their online activities.

A VPN application ensures online privacy, enhances security, and enables users to bypass geographic restrictions by virtually relocating their connection to a different server location.
