Well they are a serious company with serious engineering capabilities. Just know that whoever runs the control server can control your network, and almost everyone uses Tailscale’s centralised control server, so they control the networks of almost all of their customers.

Just FYI unless you self-host headscale, tailscale is centralised and not private. They claim it is end to end encrypted but their proprietary centralised control server distributes the keys, so they could very easily MITM you.

Tailscale is good tech and good crypto, but Applied cryptography cannot solve a security problem. It can only convert a security problem into a key-management problem, and tailscale does not do decentralised key management.
