A VPN (Virtual Private Network) enhances online privacy by encrypting a user's internet connection and masking their IP address. This secure tunnel protects user data from potential eavesdroppers, such as hackers and government entities, while browsing. Additionally, VPNs allow users to access geographically restricted content by routing their connection through servers in different regions. As a result, users can maintain anonymity and enjoy greater security on public Wi-Fi networks or while accessing sensitive information.
