About Exein
Exein is a cybersecurity company that protects Physical AI systems, Linux environments and RTOS devices. It sells an all-in-one runtime security platform that is embedded directly into firmware. Its customers are manufacturers and operators of connected machinery, energy infrastructure, healthcare devices, semiconductors, robotics, critical infrastructure and automotive systems. The company's approach is to run security at the core of the operating system, at the layer between hardware and application. Exein Runtime detects and blocks threats on the device in real time, while Exein Analyzer finds and fixes firmware vulnerabilities inside the build environment. The platform is built for resource-constrained environments and is written in Rust with eBPF support. Exein also helps customers meet rules such as the EU Cyber Resilience Act and the US Cyber Trust Mark. It reports over one billion devices protected at runtime, more than one million high-severity vulnerabilities uncovered and over one hundred thousand attacks blocked.
