Exein has picked up $270 million in fresh funding and now sits at a $1.7 billion valuation. That makes it the highest-valued cybersecurity startup in Europe, and it gives the company more fuel for a push into the US and Asia-Pacific.
Headline led the round, with Sofina, Goldman Sachs, the European Investment Bank Group through ETCI, KfW Capital and T.Capital joining in. A long list of existing backers also took part, including Balderton, HV, Intrepid Growth Partners, 33N Ventures, Lakestar, Supernova Invest, Blue Cloud Ventures and Geodesic Capital. The round was heavily oversubscribed. Exein also expanded its revolving credit facility with J.P. Morgan, with KfW coming in as an additional lender.
The numbers behind the raise help explain the appetite. Exein says its valuation has risen thirty-fold in two years, and it reported a fourfold increase in ARR in the first half of 2026. Around half of its revenue already comes from Asia-Pacific, where the company is active across Europe, APAC and the US.
The company is betting that security for autonomous machines will become a major market. It has been building embedded and runtime security for intelligent systems, launched Photon earlier this year to block malicious execution at the kernel level, and is now training a proprietary foundation model on telemetry from more than two billion devices running its technology. Exein plans to use that model to launch autonomous security agents by late 2026, with the first foundation models expected in early 2027.
That push comes as Exein says attacks are arriving faster and with less human effort behind them. The company says it is now detecting about 5,000 new non-repetitive attacks each week, five times the level seen a year ago. The new money will help it expand in robotics, autonomous systems and Physical AI, add US staff, open a Bay Area office and look at acquisitions as it broadens the platform.
My take — AI-written commentary, not fact-checked reporting
Exein is making the right bet: if machines are going to act in the real world, security can’t stay stuck in cloud-era habits. The more interesting part is the company’s refusal to treat machine telemetry like a side quest; that’s the asset here. Everyone else can keep pretending that generic AI tools are enough until the patch window hits zero and the robot starts moving.
