A normal VPN, often referred to as an open-source VPN, is a software or hardware tool designed to encrypt internet traffic, providing secure communication. It is characterized by being freely available, open-source, and typically symmetric encryption, which offers strong security and performance. Examples include OpenVPN, which supports a wide range of protocols and is trusted for its reliability. While there are proprietary VPNs, the term "normal" often refers to open-source options like OpenVPN, which are user-friendly and widely used.
