The Network You'd Build If You Could Start Over
Hardware-defined networks can’t follow your infrastructure to the cloud, the edge, or the field. ZeroTier replaces them with cryptographic identity and secure peer-to-peer connectivity, on ZeroTier One or post-quantum ZeroTier Quantum.

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:
- Devices join networks using cryptographic identity
- Traffic is encrypted end‑to‑end
- Connections are established peer‑to‑peer whenever possible
- Policy is centrally defined and enforced locally at every endpoint
Choose the Platform Right for You
ZeroTier Quantum
The first networking platform designed for the post‑quantum era.
Built for environments where security, sovereignty, and resilience are non-negotiable. CNSA 2.0–aligned, self-hosted, or air-gapped.
ZeroTier One
The networking platform trusted by millions of devices worldwide.
Simple to deploy. Infinitely flexible. Built for developers, operators, and distributed systems, with a FIPS 140-3 validated variant.
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.
Networks can span
- Public clouds
- Private data centers
- On‑prem environments
- Self-hosted and air-gapped networks
- Remote devices and edge systems
Core Features
Platform Capabilities
ZeroTier secures distributed networks across cloud, data center, edge, and field.
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.
Simple
Deploy networks in minutes with the lightweight ZeroTier Agent.
Resilient
Peer-to-peer connectivity removes single points of failure. Multipath failover keeps traffic moving when links degrade.
Secure
All traffic is authenticated and encrypted by default, with FIPS 140-3 validated cryptography available (NIST CMVP #5424).
ZeroTier powers secure connectivity for organizations operating in the world’s most demanding environments.
