Exein, an Italian cybersecurity startup, has secured $270 million in a Series C funding round, achieving a valuation of $1.7 billion. The funding aims to enhance security for physical AI systems, which are increasingly vulnerable to machine-speed cyberattacks. Exein's technology, embedded in over 2 billion chips globally, focuses on kernel-level security to protect devices like drones, robots, and autonomous vehicles. The company has reported a fivefold increase in detected attacks, now averaging 5,000 new threats per week. Exein plans to introduce an agentic security architecture by the end of 2026 and a proprietary foundation model for AI security in early 2027. This development is critical as AI technology transitions from cloud environments to physical systems, expanding the attack surface for malicious actors. The funding round was led by Headline, with participation from several notable investors, including Goldman Sachs and the European Investment Bank.
