WireGuard is one of the most efficient, modern VPN protocols available today, while also remaining secure and open-source. With that said, while the protocol itself is sound, managing your own WireGuard network can be difficult depending on your network type, the number of users that you need to have, and the access limits that you want to set. That’s where Tailscale comes in, built on top of WireGuard while simplifying many parts of the process.
