WireGuard®, a modern, simple VPN that uses state-of-the art cryptography, is extremely fast. It is designed to be simpler, faster, more efficient, and less complicated than IPsec while avoiding major headaches. It is designed to be significantly faster than OpenVPN. WireGuard is a general-purpose VPN that can be used on embedded interfaces as well as supercomputers. It is suitable for many different situations. It was initially released for Linux, but it is now cross-platform (Windows and macOS, BSDs, iOS and Android) as well as widely deployable. Although it is still in heavy development, it may be the most secure, easy-to-use, and simple VPN solution in the market. WireGuard is designed to be as simple to set up and deploy as SSH. WireGuard makes it easy to establish a VPN connection by exchanging very basic public keys. This is exactly the same as exchanging SSH keys. It can even roam between IP addresses, much like Mosh.
