Spin up secure, private, and battlefield-ready networks in minutes, without buying any new hardware. ZeroTier works anywhere, adapts fast, and locks down comms with defense-grade encryption. Self-heal, self-host, stay air-gapped, and stay in control.
Deploy simple, resilient, and secure networking anywhere with no hardware and no hassle.
Get mission-ready networks on your existing infrastructure. From sensors to UAVs to tactical systems, ZeroTier creates secure connections without hardware upgrades.
Establish secure connectivity in minutes, even in contested or disconnected environments. Perfect for rapid response, forward operating units, or remote mission deployments.
Ideal for short-lived or mission-specific deployments, ZeroTier enables fully software-defined comms that can be spun up fast and torn down clean.
Manage networks across air, land, sea, and cyber from a single interface. ZeroTier’s overlay spans every environment, simplifying coordination and reducing manual intervention for multi-domain operations.
“ZeroTier provides the industry’s best platform for simplifying secure connectivity. It has saved us significant development time."”
Built for dynamic threat environments, ZeroTier networks stay up when conventional systems fail. This makes it ideal for internet-degraded or denied environments, remote sensors, and tactical VoIP systems.
Downtime isn’t an option when lives are on the line. ZeroTier uses redundant systems and adaptive routing to maintain availability, even if nodes drop or links fail. Defense users report sub-second failover.
Each device is assigned a permanent, unique cryptographic ID, making it easy to route traffic even when assets are on the move or using unreliable connectivity. No static IP needed.
ZeroTier creates direct links across firewalled, air-gapped, or NAT-constrained environments without manual setup, ideal for coalition operations, remote deployments, and edge scenarios.
ZeroTier's multipath routing automatically selects the best path across networks to maintain uninterrupted comms. Whether moving between networks or recovering from an outage, mission-critical data keeps flowing.
“We’ve tested all the options, and ZeroTier is the fastest and most flexible solution for our battlefield use case.”
In defense environments, every connection must be secure by design. ZeroTier encrypts every packet, authenticates every device, and offers future-ready cryptography to keep critical systems protected from nation-state level threats.
Data in motion should never be vulnerable. ZeroTier creates direct peer-to-peer connections between nodes and encrypts every packet from source to destination. No middlemen, no exposure.
Zero-trust is essential for tactical and distributed defense networks. With ZeroTier, each device in your network is verified using a unique cryptographic ID. No trusting unknown devices or guessing what's allowed to connect.
Traditional role-based access falls short in complex missions. ZeroTier’s ReBAC model uses real-world relationships to define permissions dynamically, so you stay in control.
Discover how ZeroTier can help you stay air-gapped, connected, and in command.
