WireGuard® is a modern VPN solution that is not only incredibly straightforward but also fast, built on advanced cryptography. Its goal is to outperform IPsec by being quicker, easier to use, more streamlined, and less troublesome. WireGuard is positioned to deliver superior performance compared to OpenVPN as well. Engineered as a versatile VPN, it can operate on both embedded devices and high-performance supercomputers, making it adaptable for a variety of scenarios. Originally developed for the Linux kernel, WireGuard has since become available across multiple platforms, including Windows, macOS, BSD, iOS, and Android, enhancing its accessibility. Although it is still evolving, it is already seen as one of the most secure, user-friendly, and straightforward VPN options available today. Configuration and deployment are designed to be as seamless as SSH, with VPN connections established through the simple exchange of public keys—similar to the method used for SSH keys—while WireGuard takes care of all other processes automatically. Additionally, it supports roaming across different IP addresses, resembling the functionality of Mosh, which enhances its usability for mobile users. Overall, WireGuard stands out in the VPN landscape due to its blend of cutting-edge technology and user-centric design.
