A VPN server is the remote endpoint that receives encrypted traffic from a user’s device. It decrypts the tunnel, forwards the user’s requests to the internet, and sends the responses back through the same encrypted path. To websites and local network observers, the VPN server often becomes the visible source of the connection instead of the user’s device.
This matters because the server is a key trust point in the security chain. On public Wi-Fi, a VPN server helps protect data in transit from nearby snoopers and reduces what an attacker can learn if they capture packets on the local network. Defenders use VPN servers for secure remote access, privacy, and safer browsing on untrusted networks. Attackers may abuse or target VPN servers to hide origin, relay traffic, or exploit weakly configured services, which is why strong authentication, patching, logging, and limited exposure are important.
