The Network You'd Build If You Could Start Over

ZeroTier creates secure, programmable network overlays that connect devices, infrastructure, and applications anywhere.

Overview

How ZeroTier works

ZeroTier replaces physical network boundaries with cryptographic identity and secure peer‑to‑peer connectivity.

Each network member is identified, authenticated, and connected using four core mechanisms:

Each network member is identified, authenticated, and connected using four core mechanisms.
