ZeroTier

ZeroTier at a glance

ZeroTier is a popular software-defined networking tool that creates secure virtual networks connecting devices anywhere, an alternative to traditional VPNs. ZeroTier ships regular client releases plus fixes; as networking software with reach into your private network, keeping clients current and access controlled matters.

For admins the security model rests on network membership and the controller: authorize only devices you control onto a network, use the managed rules to segment access, and consider self-hosting the controller for full control. Keep clients current for security and compatibility fixes; managed fleets deploy through software distribution. Because ZeroTier can bridge networks, configure routes and gateways deliberately to avoid unintended exposure. After updates, verify connectivity and membership. Enforce a minimum client version where you can. Track releases so security fixes reach every device; patchletter surfaces new ZeroTier versions.
