We’re glad to announce that Exein has raised €100 million in new funding in 2025. This new investment follows July’s Series C funding, and brings our total collection of the year up to €170 million.
This new investment is led by Blue Cloud Ventures, with participation from HV Capital, Intrepid Growth Partners, Geodesic, and J.P. Morgan, and will help accelerating our global expansion and answer the increasing demand for protection against cyber attacks.
New investments to support M&A and next-generation AI security
Thanks to our collection we will advance a new generation of embedded runtime security solutions for connected devices, including AI-driven protection to secure AI infrastructure and large language models (LLMs), with the first wave of this breakthrough to be unveiled at RSAC 2026.
It will also support our multi-deal M&A programme in 2026 in Europe and the US, and accelerate international expansion, particularly in the US and APAC markets.
A year of hyper-growth
The latest funding follows shortly after our €70 million Series C and is a testament to Exein’s growth: a 5× year-on-year revenue increase, an expanding customer footprint across critical infrastructure and advanced manufacturing, and major partnerships with leading manufacturers and chipset providers, including Kontron and MediaTek. Together, these milestones underscore Exein’s strong commercial performance and the growing demand for device-level cybersecurity.
Cybersecurity and compliance enablers
As cyberattacks increasingly target the physical world, shutting down hospitals, and airports, disrupting transport systems, and compromising supply chains, manufacturers are moving away from traditional perimeter defences and towards protection embedded directly in the device.
Exein’s platform places AI-powered runtime security inside the firmware itself, enabling devices to detect, contain and respond to threats in real time, even without continuous connectivity.
This model gives manufacturers deeper integrity and provenance checks across their entire supply chain, and at the same time ensure compliance with global cybersecurity regulations such as RED 3.3, the forthcoming EU Cyber Resilience Act, and the US Cyber Trust Mark. With connected devices now the world’s largest and fastest-growing attack surface, Exein has positioned itself as the world’s largest embedded runtime security provider.
Gianni Cuozzo, Founder & CEO, Exein: “This round demonstrates just how rapidly Exein is growing. In just one year, we’ve become a truly global company, expanding across the US and Asia-Pacific, and emerged as the world’s largest embedded runtime security provider by devices protected. This new funding allows us to accelerate even faster in 2026 and to support our M&A strategy as we scale into new markets. It will also enable us to introduce the next generation of runtime security technology, probably the most significant advance in our field in almost a decade. We’ll unveil it at RSAC in Q1, as we continue building the digital immune system that will protect the connected world for years to come.”
Rami Rahal, Founder & Managing Partner at Blue Cloud Ventures: “Connected devices are now the largest and least protected attack surface in the world. Exein’s mission is a vital one, and its solution - to place intelligent, real-time defence inside the device itself - is exactly what the market needs as cyberattacks increasingly spill into the physical world. We’re proud to back Exein as it builds the digital immune system for the next decade of global infrastructure.”
Max Hauer, Innovation Economy Banking at J.P. Morgan: “Securing the world’s connected devices is becoming essential to the resilience of modern infrastructure. Exein is playing a pivotal role in this, and we are pleased to support the company as it enters its next phase of global growth.”
