## What does ZeroTier do?

ZeroTier is a software-defined networking platform that provides secure connectivity across distributed infrastructure, including devices, cloud environments, on-premises systems, and edge deployments. The platform enables organizations to connect globally dispersed infrastructure without physical hardware, proprietary appliances, or complex VPN configurations.

The core ZeroTier platform operates as a programmable overlay network, enforcing security and connectivity directly at each endpoint rather than through centralized chokepoints. It supports multi-cloud, hybrid, and air-gapped environments and is designed to replace traditional networking stacks with a simpler, software-based approach.

ZeroTier has announced ZeroTier Quantum, described as a post-quantum networking platform that is CNSA 2.0 compliant and deployable in air-gapped environments. This offering targets organizations preparing for post-quantum cryptography (PQC) requirements, with policy enforcement applied locally at every endpoint.

The platform serves a range of industries including defense, manufacturing, government, IoT/edge computing, and enterprise IT. Customers include organizations such as Thales, Leidos, NTT Data, TD Synnex, Volvo, and Advantech, with over 3 million devices connected worldwide.

Key platform characteristics include:
- No hardware requirements for deployment
- Elimination of legacy VPN complexity
- Decentralized security enforcement at endpoints
- Support for distributed and air-gapped environments
- Post-quantum cryptographic protections via ZeroTier Quantum

ZeroTier offers its platform under a SaaS model and targets enterprise IT teams, managed service providers, telcos, defense contractors, and industrial operators.
