Exein has raised €70 million in a Series C funding round, an important milestone that accelerates its mission to build a digital immune system providing embedded IoT security solutions for connected devices.
The round was led by Balderton and included participation from Supernova and Lakestar, along with follow-on investments from previous investors such as 33N, United Ventures, and Partech.
New investments for growth in IoT and AI cybersecurity
With this new capital, Exein will accelerate its global expansion into key markets such as the United States, Japan, Taiwan, and South Korea, while further strengthening its leadership among European companies.
It will also drive the development of its next-generation technologies, including runtime security solutions designed for AI infrastructure and large language models (LLMs).
Building the immune system of digital life
This investment highlights the growing urgency to address the increasing number of cyberattacks, which currently threaten entire industries and critical infrastructures.
Exein provides advanced security directly on the device to protect IoT and embedded systems from within, in real time, functioning as a digital immune system.
Furthermore, Exein’s technology helps ensure compliance with global cybersecurity regulations, both old and new, including the upcoming Cyber Resilience Act, RED 3.3, and the US Cyber Trust Mark.
For this reason, leading manufacturers and chipset designers such as MediaTek, Supermicro, Kontron, SECO, and AAEON trust the Exein platform to protect over 1 billion devices at runtime.
Strengthening European tech foundations
Following its Series B in July 2024, this new round reflects the momentum Exein has gained, with 450% year-over-year growth. It will also support its commitment to actively pursue strategic acquisitions to expand its reach within the cybersecurity ecosystem.
Exein’s founder and CEO, Gianni Cuozzo, describes the current state of both the company and the cybersecurity industry: “Exein’s extraordinary growth is a testament to the urgent demand to secure devices that are ubiquitous in our daily lives. Embedded security at the device level is fundamental, and we are proud to support manufacturers in delivering the highest levels of security, giving them confidence in knowing they comply with the latest security legislation. I am extremely proud to be strengthening the foundations of European tech innovation and to have the trust of our partners and investors as we expand globally and continue our mission to build the digital immune system for the connected world.”
Elena Moneta, Principal at Balderton, echoes these sentiments: “We live in an era where everything — from rail networks to industrial machinery — is connected and therefore exposed. Exein tackles this threat where it begins: on the device itself, embedding real-time security on the edge — continuously monitoring, learning, and responding. There is no better team to take on this challenge.”
