# VPN A VPN is a virtual private network. It uses a secure connection between a computer and a network or two networks. It can be used to display another [IP address](/wiki/ip_address.md) but does not make tracking or fingerprinting of the device impossible. For the latter a plugin like [Chameleon](/wiki/chameleon.md) for [Firefox](/wiki/firefox.md) can be used. VPNs feature a server and a client side. ## VPN implementations This section lists various VPN implementations. - [OpenVPN](/wiki/openvpn.md) is probably the most well known VPN implementation. - [WireGuard](/wiki/wireguard.md) is a modern, fast and secure implementation of the VPN protocol. It is free and open-source. - [Global Protect](/wiki/globalprotect.md) is a proprietary VPN that is mostly used by corporation and learning facilities.
