One of the VPN (Virtual Private Network, or Virtual Private Network) is a technology that creates a secure, encrypted connection between your device and the internet.

Traffic redirection
O traffic redirection In a VPN, this happens when your data bypasses the traditional path to the internet and is routed through an intermediary server operated by the VPN itself.
