Edge Gateway Firmware

Hardened Linux and RTOS gateway firmware with secure boot, signed OTA and industrial protocols.

Problem

What we are solving

Field gateways were prototypes that shipped. No secure boot, brittle OTA, mixed protocol stacks and a vendor that has now disappeared.

Solution

How it works

Hardened gateway firmware on Yocto Linux or Zephyr RTOS with secure boot, signed OTA, OPC-UA, Modbus, MQTT, CAN and rail-specific TCN, plus a long-term security maintenance posture.

Use Cases

Where it ships

Industrial Automation

Brownfield plants needing a secure bridge from OT protocols to cloud platforms.

Rail Onboard Computing

TCN, MVB and Ethernet Train Backbone gateways for rolling stock retrofit programs.

Energy Substation Edge

Substation gateways aggregating IEDs and protective relays for centralised monitoring.
