Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
PRIVATE WiFi is a virtual private network (VPN) security software that protects your identity and sensitive information by encrypting everything you send and receive over public WiFi networks so that your online activity is invisible to threats.
A VPN maintains an authenticated, encrypted tunnel for securely passing data traffic over public networks (typically, the Internet.)Other VPN types are IPsec VPNs, which are useful for point-to-point connections when the network endpoints are known and remain fixed; or SSL VPNs, which provide for access through a Web browser and are commonly used by remote workers.
A VPN does not make one's Internet use private. Users can still be tracked through tracking cookies and device fingerprinting, even if the user's IP address is hidden. [15] A VPN can log the user's traffic, although this depends on the VPN provider. [15] A VPN does not make the user immune to cyberattacks. [15]

OpenVPN is a virtual private network (VPN) system that implements techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities.
WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs). [5] It aims to be lighter and better performing than IPsec and OpenVPN, two common tunneling protocols. [6]
DMVPN is initially configured to build out a hub-and-spoke network by statically configuring the hubs (VPN headends) on the spokes, no change in the configuration on the hub is required to accept new spokes. Using this initial hub-and-spoke network, tunnels between spokes can be dynamically built on demand (dynamic-mesh) without additional ...
