exein

Exein is a Physical AI and embedded/IoT cybersecurity company (Italy) that secures connected devices, firmware, and Linux/RTOS embedded systems. Its platform pairs on-device runtime threat detection (Exein Runtime) with AI-powered firmware analysis and SBOM ingestion (Exein Analyzer), mapping findings to standards including the EU Cyber Resilience Act, ETSI EN 303-645, IEC 62443, RED 3.3, and the US Cyber Trust Mark. Exein does not publish a hosted public REST API; its developer surface is open-source security tooling in the exein-io GitHub organization — notably Pulsar (an eBPF-powered runtime security agent) and Kepler (a NIST-based CVE lookup store and API). Surfaced as a portfolio company of balderton-capital, hv-capital, and partech.

exein is profiled on the APIs.io network. Tagged areas include Company, Security, Cybersecurity, IoT, and Embedded.

exein’s developer surface includes documentation, engineering blog, CLI, and 7 more developer resources.
