Sternum

Sternum is an Israeli cybersecurity company focused on embedded device and IoT security. The company develops technology that is embedded directly into firmware, enabling runtime protection and observability for IoT and connected devices without requiring cloud connectivity or changes to existing hardware.

Sternum's core product is an agent that runs inside device firmware and provides real-time threat detection, integrity protection, and telemetry for embedded systems. The problem it addresses is specific: traditional endpoint security cannot run on resource-constrained microcontrollers found in medical devices, industrial controllers, and consumer IoT hardware. Sternum's approach instruments the firmware at the binary level, which means it can be deployed across a wide range of architectures without access to source code. The primary buyers are device manufacturers — OEMs in medical, industrial, and smart-home verticals — rather than end-user enterprises.
