Overview
Exein builds on-device / embedded runtime security that aims to stop attacks below the application layer — including Photon, which the company says blocks malicious activity at the kernel before damage spreads. Customers and chipset partnerships historically span industrial, automotive, energy, and device OEMs; the September 2026 raise funds U.S. and APAC expansion plus Physical AI security agents planned for late 2026 / early 2027.
Why Exein is interesting
Exein just printed a $270M Headline-led round at a $1.7B valuation after raising about $170M in 2025, pivoting the story from IoT device protection toward kernel-level security for robots, vehicles, and other physical AI — with a proprietary foundation model trained on telemetry from a company-claimed 2B+ devices.
Product & use cases
Embedded runtime security and kernel-level defenses for connected devices, with a roadmap for autonomous security agents aimed at robots, drones, autonomous vehicles, and other Physical AI systems.
- Runtime protection for IoT, industrial, and automotive embedded software
- Chipset / OEM partnerships that ship security onto devices at scale
- Physical AI security where agents must be constrained below the application layer
