ZeroTier One connects devices, servers, and applications into one secure virtual network, no matter what sits between them. Cryptographic identity controls who joins. Peer-to-peer connections keep it fast. Millions of devices already run on it.
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:
ZeroTier One combines lightweight software agents, a secure peer-to-peer networking layer, and a flexible control plane into one distributed networking platform.
ZeroTier Central provides the management interface for configuring and operating networks.
From Central, administrators can:
Need full infrastructure control? ZeroTier One Enterprise supports self-hosted controllers and air-gapped networks.
The control layer defines how networks behave.
Administrators use it to manage:
Control information is distributed to nodes, which enforce policy locally.
The ZeroTier data layer forms a secure peer‑to‑peer virtual network.
Devices communicate directly whenever possible, establishing encrypted connections across the internet, private WANs, or isolated networks.
Every device that joins a ZeroTier network runs a lightweight software agent.
This agent installs as a background service and creates a virtual network interface on the host system.
Agents run across servers, desktops, mobile devices, routers, and embedded systems.
ZeroTier networks operate as secure virtual networks on top of existing infrastructure.
Connectivity is defined through identity and policy rather than physical topology.
ZeroTier enables modern distributed networking across environments.
Create private virtual networks that span cloud providers, data centers, and devices.
Connect infrastructure across multiple cloud providers without complex routing or VPN configuration.
Securely connect thousands of devices, servers, or embedded systems into unified networks.
Define network behavior through programmable policy tied to node identity.
Support both Ethernet bridging and routed IP networking for flexible infrastructure integration.
Control networks via APIs and automation to integrate with modern infrastructure workflows.
Modern software‑defined networking for distributed infrastructure.
ZeroTier One allows organizations and developers to create secure virtual networks that connect devices and infrastructure anywhere.
Networks can be deployed in minutes and scale globally with no specialized networking hardware needed.
