IoT cybersecurity startup Exein today announced raising $270 million in an oversubscribed funding round that brings the total raised to over $600 million and its valuation to $1.7 billion.
The investment round was led by Headline, with participation from Sofina, Goldman Sachs, the European Investment Bank Group, KfW Capital, Balderton, Lakestar, and several other venture firms.
Founded in 2018, Italy-based Exein has built embedded and runtime security technology that targets vulnerabilities, attacks, and compliance issues in IoT devices.
The solution provides threat monitoring, detection, and containment, complemented by a kernel-level preemptive runtime security solution designed to block attacks before they execute.
Exein is now working on a proprietary foundation model specifically crafted for Physical AI security, trained on real-world machine activity.
The new agentic security architecture will power autonomous agents designed to protect systems at machine speed, Exein says.
