ZeroTier Platform is a software-defined networking solution that creates secure virtual network overlays connecting devices, infrastructure, and applications across distributed environments. How it works: - Each network member is assigned a cryptographic identity used for authentication and identification - Traffic between nodes is encrypted end-to-end - Connections are established peer-to-peer wherever possible, removing single points of failure - Network policy is centrally defined and enforced globally across all members Network scope: - Networks can span public clouds, private data centers, on-premises environments, and remote/edge devices - Supports both Layer 2 (Ethernet bridging) and Layer 3 (routed IP) networking - Enables cloud-to-cloud connectivity without complex routing or VPN configuration Platform offerings: - ZeroTier One: The standard networking platform for developers, operators, and distributed systems, trusted by millions of devices - ZeroTier Quantum: A variant designed for post-quantum cryptographic environments, targeting use cases requiring high security and sovereignty Management and control: - Networks are managed via APIs and automation tooling - Policy is tied to node identity rather than physical network topology - Supports large-scale device fleets including servers, embedded systems, and remote endpoints ZeroTier is used across industries including defense, enterprise IT, IoT, and edge computing, with noted customers including Thales, Leidos, NTT Data, Volvo, and others. The platform has over 3 million devices connected worldwide.
