Sternum Runtime Protection

Sternum Runtime Protection is an agentless runtime security solution for IoT and embedded devices, built on the company's patented EIV™ (Embedded Integrity Verification) software technology. The product uses binary instrumentation to auto-profile firmware — including third-party libraries — and deploys verification checks across all exploitation paths to prevent code and memory manipulation attempts. It integrates directly into the firmware build, testing, and deployment process, running as part of the device's code with no reliance on external communication and a reported CPU overhead of 1–3%. Key protections include defense against MITRE's Top 25 Most Dangerous Software Weaknesses applicable to IoT, such as buffer overflows, command injections, and execution flow manipulations. The solution also covers known vulnerabilities, zero-day and one-day threats, and software supply chain risks, including third-party libraries used for communication, encryption, authentication, and OTA updates. A cloud platform component provides XDR-like threat detection capabilities, including intelligence on indicators of attack (IoA) and indicators of compromise (IoC), covering unauthorized access, DDoS, and brute force attempts. Security data can be sourced to external SOC, SIEM, or SOAR platforms, or analyzed via Sternum's own interactive dashboards. For each mitigated attack, the platform provides forensic context to support root cause analysis. The solution is designed specifically for resource-constrained embedded environments and has been validated by partners including NXP Semiconductors, Medtronic, Telit, the Linux Foundation (Zephyr RTOS), and HARDWARIO.
