History

Founded in 2019 by Google engineers Avery Pennarun, David Crawshaw, David Carney, and Brad Fitzpatrick,[5] the company secured funding of $12 million in a Series A round in November 2020 led by Accel with seed investors, Heavybit and Uncork Capital participating.[6] In May 2022, the company became a unicorn, raising a $100 million Series B round, led by CRV and Insight Partners, with participation from existing investors.[7]

The company's name is inspired from a research paper The Tail at Scale published by Google.[8]

Software

The open-source software acts in combination with the management service to establish peer-to-peer or relayed VPN communication with other clients using the WireGuard protocol.[9] [10] Tailscale can open direct connection to the peer using NAT traversal techniques such as STUN or request port forwarding via UPnP IGD, NAT-PMP or PCP.[11] If the software fails to establish direct communication it falls back to using DERP (Designated Encrypted Relay for Packets) protocol relays provided by the company.[12] The IPv4 addresses given to clients are in the carrier-grade NAT reserved space. This was chosen to avoid interference with existing networks.[13] The configuration also allows routing of traffic to networks behind the client on some clients.

Supported platforms

The Tailscale client software supports a number of operating systems and embedded software systems,[14] including:

A Kubernetes operator[17] and Docker images[18] are also available.
