The main benefit of using a virtual private network (VPN) is enhanced online privacy and security. A VPN creates a secure, encrypted tunnel between the user’s device and the internet, protecting sensitive data from potential threats such as hackers and malware. By masking the user's IP address and enabling access to servers in different geographical locations, a VPN also allows for greater online anonymity. This is particularly valuable when using public Wi-Fi networks, as it minimizes the risk of data breaches. Overall, VPNs empower users to navigate the internet with increased security and freedom.
