Exein raises $270M to secure the AI moving into drones and robots
What's the deal? Italian cybersecurity startup Exein has raised $270 million in a late-stage round led by US-based Headline, valuing the company at $1.7 billion post-money. Exein builds technology that secures hardware at the processor level, and it will use the funding to adapt its approach for physical systems that run on AI.

Why now? AI is powering more hardware — robots, autonomous vehicles, drones, and phones — which creates a new attack surface for malicious actors. "AI is leaving the data centre and coming to the physical world, to cameras and drones," chief technology officer Giovanni Alberto Falcione told Resilience Media.
What's the endgame? Exein's physical AI product is still in development. A new agentic security architecture is due by the end of this year, followed by a foundation model for tracking and securing physical AI in early 2027.
The trajectory: The company has grown fast. In July 2025 it raised $80 million at a valuation of around $400 million; by December 2025 it had raised a further $115 million at just over $800 million. Annual recurring revenue for the first half of 2026 grew four-fold.
Exein says the valuation makes it currently the most valuable privately held security startup in Europe.
The signal: Europe wants to build sovereign technology that is less dependent on other nations, and processors are central to that thesis. A homegrown champion securing hardware for defence and critical industries could become a strong bargaining chip in future supply-chain talks — even if Europe's chipmakers never overtake Nvidia.
