Building the World’s Digital Immune System
Exein Extending Series C with additional €100M
Exein announced an additional €100 million in funding this week, extending its Series C and bringing total capital raised in 2025 to €170 million. The round is led by Blue Cloud Ventures, with participation from HV Capital, Intrepid Growth Partners, Geodesic and J.P. Morgan, which also provided a financing facility.
A year of hyper-growth
Notably, this extension comes just five months after Exein’s €70 million Series C and caps a year of exceptional momentum. The company has delivered 5x year-on-year revenue growth, nearly doubled its valuation since July, and scaled its embedded security platform to more than 1.5 billion devices globally. Exein expects to surpass two billion protected devices in production by Q1 2026 .
Securing the Largest—and Least Protected—Attack Surface
At the core of Exein’s growth is a clear architectural shift in cybersecurity. As connected devices proliferate across critical infrastructure, manufacturers are moving away from perimeter defenses toward protection embedded directly in firmware. This approach is increasingly essential as cyberattacks spill into the physical world and regulatory pressure for device-level security accelerates (including RED 3.3, EU Cyber Resilience Act, US Cyber Trust Mark) .
What this means: Product, M&A and Global Scale
The new capital will support three priorities: advancing next-generation runtime security, including protection for on-device AI and LLMs; executing a multi-deal M&A strategy in 2026 across Europe and the US; and accelerating international expansion, particularly in North America and APAC.
Why This Matters
As connected devices become the world’s largest and least protected attack surface, Exein is positioning itself as foundational infrastructure — a “digital immune system” for the modern economy. This Series C extension reflects both the urgency of the problem and Exein’s emergence as a category-defining leader in embedded cybersecurity.
