Pennarun says that, even if a company uses Tailscale to route public-facing browser traffic through nodes like Linux, Windows, macOS, and Android TV devices, only these devices see decrypted traffic or have any view into what traffic they’re sent. But by other metrics, the company has performed well in the face of competition from ZeroTier and Cloudflare One. In addition to hundreds of thousands of users on its free plan, which Tailscale recently debuted, the startup claims to have paying government clients as well as private sector customers including Oxide Computing Company, Dusty Robotics, and VersaBank. “By bridging the two, Tailscale provides an option that makes teams more productive, eliminating connectivity problems and complex network architecture, but also secure by default, because every connection is always secure.”Tailscale’s product is built on WireGuard, a communication protocol and open source software that implements encrypted VPNs in enterprise environments. Tailscale is razor-focused on user experience and security.”
