Exein

We’ve spent years learning how machines behave and how to protect them. With $270m in new funding, we’re taking that work further through global expansion and a foundation model for Physical AI security, trained on telemetry generated through Exein technology across over two billion devices.

We are a unicorn! 🦄 Exein raised $270M at a $1.7B valuation to build the security layer for Physical AI. The new funding allows us to expand globally our protection for intelligent machines that use AI to perceive, make decisions, and act in the physical world. The round is led by Headline, with participation from Sofina, Goldman Sachs, the European Investment Bank (EIB) Group through ETCI, KfW Capital, and T.Capital and continued backing from Balderton, HV, Intrepid Growth Partners, 33N Ventures, Lakestar, Supernova Invest, Blue Cloud Ventures, and Geodesic Capital. This comes alongside an upsized revolving credit facility led by J.P. Morgan, with KfW joining. We want to thank our investors for their continued support and belief in our vision. We're also grateful to our partners and customers, whose trust and collaboration help us rise to the challenges of an always-evolving industry. Lastly, we want to dedicate a few words to our global team across Europe, Asia and the Americas. Whether you're celebrating this milestone at HQ, in one of our offices, or on a plane between time zones, thank you. Your constant commitment and drive for excellence are what allow Exein to build the global standard for security in the connected world. Read the full story on the Financial Times 👇

Exein has entered a new chapter of global growth. Today, we announce $270M in new funding at a $1.7B valuation, making Exein one of Europe’s most valuable cybersecurity startups. Led by Headline, with participation from Sofina, Goldman Sachs, KfW Capital, European Investment Fund and Deutsche Telekom, the oversubscribed round reflects Exein’s momentum and the urgency of securing intelligent machines. This funding will accelerate Exein’s expansion across the U.S. and APAC, strengthening our position as an international player in Physical AI cybersecurity. Read more at the link.

An attacker skipped password verification, gained Administrator privilege and tried to replace /etc/shadow. One Photon rule blocked the atomic rename before it landed. The password never changed, and the attacker received no signal that runtime protection had intervened.

AI’s latest models have everyone talking. But when AI operates inside machines and infrastructure, its attack surface also becomes physical. That changes what security teams need to protect and where they need to look for risk. We break down the Physical AI threat model at the link.

Exein is now the Official Physical AI Security Partner of TGR Haas F1 Team, starting this weekend at the Belgian GP! On track, a millisecond decides the race. In cybersecurity, a millisecond decides the breach. Sensors, actuators, software: F1 runs on the same Physical AI logic Exein is built to protect. From the track to real life, the mission stays the same. As connected devices and autonomous systems take on more of the decision-making — on track and off it — runtime security is essential in high-performance environments. Our technology will protect the physical AI systems and devices behind Haas F1 Team's operations, bringing Exein's security expertise into one of the most demanding technical environments in the world. With Haas, we'll be together on the biggest stage, a partnership we'll be highlighting throughout this season and beyond, with initiatives spotlighting the growing importance of cybersecurity, innovation, and technological excellence. We wish Ollie, Esteban, and the entire Haas team a great weekend at Spa, and a strong rest of the season! 🏎️
