Tailscale
Tailscale, formed in March 2019.
- It's based on peer-to-peer VPNs rather than piping all VPN traffic through a single concentrator.
- Maintains a database of endpoints on its server, so that when client X needs to talk to client Z, it fetches the endpoint details and then makes a direct connection. It's calls this a mesh network.
