Connect all of your apps, services, and devices without worrying about physical connectivity, firewalls, or VPNs.
Modern applications need access to resources spread across the cloud, on-prem, and the edge while supporting users around the world.
With ZeroTier, you can stop fighting with flaky on-site Internet service, firewalls, and cloud ingress, and spend your time building features your customers will love.
Use the same lightweight software agent to connect your servers, mobile devices, embedded/IoT systems, and developer machines.
Cut out wasted admin effort. Spin up, manage, or tear down networks easily via API calls. Provision, control, and monitor all devices as part of a larger ecosystem — without network change requests or physical access.
ZeroTier works on everything from embedded single-board computers to datacenter servers. Manage all your devices the same way, no matter where they run.
Install our packages, or build from source to integrate in a custom VM or embedded device image. Pay only as you add devices to your networks, with no upfront fees for unused capacity.
“ZeroTier connects our engineers to key resources quickly and easily, which allows our team to focus on making space simple.”
ZeroTier’s peer-to-peer overlay constantly optimizes your network for the fastest possible direct links, reducing latency and providing consistent, peak performance in mission-critical workloads.
With ZeroTier, once authenticated, your app’s traffic runs direct, peer-to-peer. No central servers, no bottlenecks. Just faster response and greater reliability for developers and users.
ZeroTier agents continually check connectivity and provide redundancy and rapid failover via multi-path connections (Ethernet, WiFi, LTE/5G, satellite, etc.)
ZeroTier network connections run on direct, peer-to-peer connections. No need to ship all of your data to a cloud provider only to send it somewhere else.
“ZeroTier provides the industry’s best platform for simplifying secure connectivity. It has saved us significant development time.”
ZeroTier protects your systems by removing the need for public access, ensuring transport security, and providing strong identity for clients and servers.
ZeroTier network peers are identified by a unique keypair, and all traffic is end-to-end encrypted. No one – not even us – can see your packets in flight.
Public service endpoints are always a target. With ZeroTier, your services stay private, and only authorized peers on the appropriate network(s) can reach them.
ZeroTier’s network transport security doesn't depend on correctly configuring TLS suites or certificate lifespans. It works perfectly with plaintext and encrypted network protocol. You can meet application-level requirements for TLS and L7 security while providing defense-in-depth for legacy protocols and clients.
Discover how ZeroTier lets you spend less time fixing networks and more time shipping features.
