ZeroTier is a secure, end-to-end encrypted, software-defined networking platform that has proved critical for modern enterprises as well as defense and government organizations, and the software and technology providers that must connect users, workloads, and devices across an increasingly fragmented digital landscape. ZeroTier One provides an encrypted, policy‑driven overlay that spans data centers, public clouds, SaaS environments, and edge locations, turning the open Internet into a reliable backbone for sensitive traffic.
For secure multi‑cloud links, ZeroTier One enables engineering and platform teams to create flat, encrypted virtual networks that seamlessly connect VNets/VPCs across different cloud providers and regions, without the complexity and rigidity of traditional site‑to‑site VPNs or proprietary interconnects. This simplifies architectures, accelerates deployment, and ensures that services in any cloud can communicate over a consistent, least‑privilege fabric.
In enterprise IT environments, ZeroTier gives network and security teams a secure way to connect users, branches, data centers, and cloud workloads without exposing internal systems to the internet or relying on legacy VPN gateways. Encrypted, identity-based connectivity enables granular segmentation and secure remote access across distributed hybrid environments.
For defense and mission-critical communications, ZeroTier’s peer-to-peer architecture, strong cryptography, and ability to operate across complex network environments make it an ideal foundation for resilient, distributed systems where availability and confidentiality are paramount.
Remote workforce networking is equally transformed. Instead of backhauling traffic through centralized VPN concentrators, users connect over a secure, identity-based overlay network where access is enforced by policy rather than location. This improves performance for modern SaaS and cloud-native applications while strengthening security.
In November 2025, ZeroTier announced a major update to its dashboard, ZeroTier Central, for ZeroTier One. This release included a completely streamlined user interface, enhanced user experience, and a modernized backend architecture designed to make network management faster, simpler, and more powerful than ever.
