Exein, a leader in embedded cybersecurity for connected devices, announced it has raised €100 million in new funding to drive international growth and accelerate the development of next-generation runtime security technologies. This round follows the company’s July Series C financing and brings Exein’s total capital raised in 2025 to €170 million.
The investment was led by Blue Cloud Ventures, with participation from HV Capital, Intrepid Growth Partners, Geodesic Capital, and J.P. Morgan, and will support Exein’s strategic initiatives in product innovation, mergers and acquisitions, and expansion into key global markets including the United States and Asia-Pacific.
Strengthening Enterprise Security at the Firmware Level
Exein’s platform embeds AI-powered runtime security directly into device firmware, enabling connected systems to detect, contain, and respond to threats in real time even when devices operate disconnected from networks. As digital attacks increasingly disrupt critical infrastructure such as hospitals, transport systems, and supply chains, this device-level approach has become essential for modern cybersecurity strategies.
The company’s technology also supports compliance with emerging global regulations, including RED 3.3, the forthcoming EU Cyber Resilience Act, and the US Cyber Trust Mark, helping manufacturers meet stringent security standards across industries.
2025: A Year of Rapid Growth
Exein’s platform already protects more than 1.5 billion devices worldwide across sectors such as energy, healthcare, automotive, industrial automation, semiconductors, aerospace, and robotics, with expectations to exceed two billion protected devices by early 2026. The company has also achieved 5× year-on-year revenue growth and expanded its global footprint through strategic customer wins and partnerships with leading manufacturers and chipset providers.

Leadership Perspectives on the Funding Round
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.”
Towards the Future of Embedded Security
The new capital will be deployed to accelerate both technological innovation and international expansion, including:
- Advancing embedded runtime security with AI-driven protection for on-device AI and large language models, with initial showcases planned at RSA Conference 2026.
- Supporting a multi-transaction M&A programme across Europe and the United States throughout 2026.
- Expanding global presence, particularly in the US and APAC markets.
