Exein, the embedded IoT cybersecurity company at the forefront of defending Europe’s critical infrastructure, has raised €70m in a Series C round. The round was led by Balderton and joined by Supernova and Lakestar, with 33N, United Ventures and Partech following on from the previous round.
The fresh capital will drive Exein’s ambitious global expansion plans across the US, Japan, Taiwan, and South Korea, as well as to strengthen its established European presence.
Identified smart devices
Hackers have identified smart devices as a back door into critical systems at businesses
Hackers, including many state-sponsored actors, have identified smart devices as a back door into critical systems at businesses and organisations, with one in three data breaches involving an IoT device.
Exein, which secures more than a billion smart devices globally, including critical infrastructure for railway networks and healthcare providers, is creating a digital immune system for connected devices, which is fast becoming the global standard for embedded IoT security.
Exein's strategic partnerships
Exein offers AI-enabled, real-time threat detection across key industries, including critical infrastructure, semiconductor, energy, automotive, healthcare, and robotics.
Achieving over 450% year-over-year growth, Exein has formed strategic partnerships with the world’s pioneering chipset and OEM/ODM manufacturers, including MediaTek, Supermicro, Kontron, SECO and AAEON.
Exein’s cybersecurity regulations
Exein’s end-point approach creates a digital immune system, securing individual devices rather than relying solely
Exein’s end-point approach creates a digital immune system, securing individual devices rather than relying solely on network defences.
This decentralised approach ensures that manufacturers can seamlessly integrate the latest security tools into their products, safeguarding devices from cyber threats and ensuring compliance with stringent global cybersecurity regulations such as Europe’s NIS2 and the Cyber Resilience Act – which comes into force in 2026 – and the US Cyber Trust Mark.
Exein’s strategic global expansion
As part of Exein’s strategic global expansion, the company is also developing runtime security solutions to secure AI infrastructure and large language models (LLMs), addressing the growing demand to secure AI and LLMs operating within devices, rather than in a centralised cloud environment.
Additionally, the funding will support Exein’s pursuit of strategic M&A opportunities in the cybersecurity industry, further enhancing its growth plans.
Building the digital immune system

Gianni Cuozzo, Founder & CEO, of Exein, says: "Exein’s extraordinary growth is a testament to the urgent demand to secure devices which are ubiquitous in our everyday lives. Embedded security at the device level is fundamental, and we are proud to support manufacturers in providing the highest levels of security, offering them confidence in knowing they are compliant with the latest security legislation."
"I’m extremely proud to be fortifying the foundations of European tech innovation, and to have the trust of our partners and investors as we expand globally and continue our mission of building the digital immune system for the connected world.”
AI enabling attackers
Elena Moneta, Principal at Balderton, says: “We’re living in an era where everything — from rail networks to industrial machinery — is connected, and therefore exposed. As critical infrastructure becomes increasingly software-defined and networked, the risks multiply, especially with AI enabling attackers to hit more targets faster than ever before."
"And they are no longer breaching through the front door; the microwave on a military ship, or the smart fish tank in a hospital waiting room - any one of these could be exploited to compromise the entire network."
"Exein tackles this threat where it begins: on the device itself, embedding real-time security on the edge — continuously monitoring, learning, and responding in real time. There is no better team to take on this challenge, and we are immensely proud to be partnering with Gianni and team as they build the cybersecurity foundation for the AI-powered, hyper-connected world ahead.”
