Exein becomes a new Italian unicorn with $270M round for physical AI security

Exein has raised a $270 million funding round led by Headline, reaching a $1.7 billion valuation. TechCrunch describes the Rome-based company as a new European unicorn and frames the round around demand for cybersecurity built for physical AI.

The key takeaway for readers: Exein is positioning device-level protection as critical infrastructure for a world where AI systems run on machines, sensors and connected hardware.

Exein’s core idea is that every device should be able to defend itself, even when it is not connected to a secure network. Its latest product, Photon, is described as a runtime security solution designed to prevent attacks at the kernel level of a device.

The company says this requires close work with manufacturers, OEMs and silicon vendors. That approach reflects Exein’s shift from its original IoT focus toward broader physical AI security.

Exein says it has secured more than 2 billion connected devices across sectors including aerospace, industrial automation, automotive manufacturing, energy, healthcare and semiconductors. The company expects physical AI to expand that opportunity because robots, drones, self-driving cars, sensors and smart appliances can run models on the edge.

The security implication is direct: as more AI-powered devices operate in physical environments, attacks against them could have operational consequences beyond software systems.

Exein plans to use the new funding for M&A, product expansion and hiring to support growth in the U.S. and Asia Pacific. The company also says it is training a foundational model for physical AI security on machine data and telemetrics, with a plan to have it ready in the first quarter of 2027.

Regulation may also shape demand: the European Union’s Cyber Resilience Act will come into full force in December 2027 and requires manufacturers to make digital products safe from cyber threats.
