IoT and fleet telematics
One secure network for your whole fleet
Give every IoT and telematics device an encrypted identity on one overlay network, reachable wherever it's deployed, across any carrier or connection.
A better model than backhauling to a hub
Direct, encrypted device connections instead of a central concentrator
Backhaul through a hub
- Every device backhauls through a central concentrator
- Routing all traffic through a hub adds latency and cost
- Heavy VPN clients strain constrained CPU and memory
- A public gateway exposes the whole flat network
With Defined
- Devices connect directly, with no central concentrator
- A lightweight agent runs on constrained hardware
- Connections follow devices across LTE, 5G, and Wi-Fi
- An identity-based firewall isolates each device
Built for devices in the field
A lightweight agent that keeps every device connected and secured, wherever it roams
Connect from anywhere
Reach devices deployed in any network, and keep them connected as they move between networks in the field.
Resource-light agent
Requires minimal power and memory to run on constrained hardware, while saturating throughput when the device allows.
Bring your own connectivity
Connect over LTE, 5G, or Wi-Fi. Our NAT traversal and relays make devices reachable even without a public IP.
Scales to your whole fleet
Peer-to-peer connections avoid a central bottleneck, so the network grows with your fleet from a handful of devices to thousands.
Connectivity failover
When a direct connection is disrupted, relays maintain encrypted connectivity so devices stay reachable in difficult conditions.
Built-in firewall
Segment your fleet from the rest of your network and the internet, isolating each device so one breach can't spread.

Frequently asked questions
It lets the devices in your fleet, including sensors, gateways, telematics units, and edge machines, reach your infrastructure and each other from anywhere, without exposing them to the public internet. With Defined Networking, every device joins one overlay network where connections are mutually authenticated with certificates, end-to-end encrypted, and limited to the hosts each device is authorized to reach.
Yes. The agent is built on open-source Nebula and is deliberately lightweight, using minimal CPU and memory so it runs comfortably on embedded hardware and edge gateways. When the hardware allows, it can also saturate the available link, so you are not trading throughput for a small footprint.
Each device makes outbound connections and re-establishes its tunnels automatically as its underlying network changes. A device can move from Wi-Fi to LTE to 5G and keep its stable overlay address, so the services talking to it do not need to track a changing IP.
Yes. Devices use UDP hole punching to connect directly even when they have no public IP, which is the norm on cellular and CGNAT. When a direct path is not available, relays maintain encrypted connectivity so the device stays reachable.
Connections are peer-to-peer, so traffic does not funnel through a central gateway that becomes a bottleneck as the fleet grows. You manage devices at scale with tags, applying configuration and identity-based firewall rules to whole groups at once instead of device by device.
Every device is issued its own certificate, so connections are mutually authenticated by identity rather than by a shared key or password. A built-in host firewall then limits each device to only the hosts and services it is allowed to reach, so a single compromised device cannot move laterally across the fleet.
Yes. Routes let a host that runs the agent bridge other equipment onto the overlay network, so legacy controllers, appliances, and sensors behind a gateway can be reached without running the client directly.
Yes. You can connect up to 100 hosts for free with no credit card required, which is enough for most teams to connect their first devices before scaling out to the full fleet.
