WireGuard® is a VPN protocol that is rapidly becoming very popular and for good reason. It aims to be much faster as well as simpler, leaner, and more useful than OpenVPN and other protocols used by any number of VPN providers. Some VPN experts refer to WireGuard as “revolutionary.”
VPNs will shield you from hackers, foreign and domestic government spies, ISPs, and everyone else who has no business recording what you haven’t chosen to share. In fact, many governments allow or even require ISPs to record your online activities and make the resultant log files available to the government. Indeed, Big Brother is watching all of us. However, a good VPN will greatly reduce the amount of personal data collected.
VPNs traditionally have added a lot of security and privacy but suffer from one significant downside: most VPNs slow down the network connection(s) because of all the processing overhead created by the VPN software. In contrast, WireGuard is believed to be the fastest of all the popular VPN protocols and is as secure or even more secure as any of the other VPN products. With fewer than 4,000 lines of publicly-visible code, WireGuard is small and simple to audit. It also employs modern cryptography and formally verified constructions.
