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.

The Platform Stack

The platform stack

ZeroTier combines lightweight software agents, a secure peer‑to‑peer networking layer, and a flexible control plane to create a distributed networking platform.

Agents and Clients

ZeroTier Central

ZeroTier Central provides the management interface for configuring and operating networks.

From Central, administrators can:

Organizations can also run self‑hosted controllers when they require full infrastructure control.

Control layer

The control layer defines how networks behave.

Administrators use it to manage:

Control information is distributed to nodes, which enforce policy locally.

Data layer

The ZeroTier data layer forms a secure peer‑to‑peer overlay network.

Devices communicate directly whenever possible, establishing encrypted connections between nodes across the internet.

This enables:

Agents and clients

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.

The agent:

Agents run across servers, desktops, mobile devices, routers, and embedded systems

Architecture

Flexible network design

ZeroTier networks operate as secure virtual overlays on top of existing infrastructure.

Connectivity is defined through identity and policy rather than physical topology.

Platform

ZeroTier One

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.
