"AI is moving out of the cloud and into the physical world, and this is the transition Exein was built for. We've developed deep expertise in how machines operate, invested heavily in the technology needed to protect them and built a global footprint that gives us an understanding of machines at a scale few others can match. Frontier models are pushing the patch window to zero. Attacks now happen at machine speed, so defense has to as well. Physical AI is the natural next step for Exein: we're building machine-time security for machine-time attacks." said, Gianni Cuozzo, Founder & CEO at Exein

Gianni and his team have incredible technical and commercial depth, they put customer trust above all else, and they have always chosen the harder, long-term-oriented path. We're honoured to help them build a global leader in Physical AI security." said, Clarey Zhu, Partner at Headline.
