The primary purpose of a VPN (Virtual Private Network) is to establish a secure connection over the internet, allowing users to safely access networks from remote locations. VPNs encrypt user data, protecting it from potential threats and unauthorized access, especially when using public Wi-Fi. This technology also enables users to mask their IP addresses, ensuring privacy and anonymity while browsing the web. Furthermore, VPNs facilitate accessing geo-restricted content and resources, making them essential for individuals seeking enhanced security and privacy in their online activities.
