The primary benefit of using a virtual private network (VPN) is enhanced security and privacy for internet users. A VPN encrypts a user's connection, ensuring data remains confidential and protected from potential eavesdroppers, such as hackers and government entities. Additionally, VPNs allow users to mask their IP addresses and access geographically restricted content, providing a level of anonymity while browsing online. These features are particularly crucial for individuals using public Wi-Fi networks.
