The main advantage of using a VPN, or Virtual Private Network, is enhanced online privacy and security. A VPN encrypts internet traffic and routes it through a secure server, making it difficult for third parties to intercept or monitor user activity. This is especially valuable when using public Wi-Fi networks, which are often vulnerable to attacks. Additionally, VPNs can help users access restricted content by masking their IP addresses and allowing them to appear as though they are browsing from a different location.
