Exein Raises €70 Million in Series C to Expand Global IoT Cybersecurity Solutions
Exein, an Italian startup specializing in embedded IoT cybersecurity, has raised €70 million in a Series C funding round. The investment, led by Balderton Capital and joined by Supernova, Lakestar, 33N, United Ventures, and Partech, will support Exein’s global expansion in the United States, Japan, Taiwan and South Korea, as well as reinforce its presence across Europe.
Scaling security from the inside out
Founded in 2018 and based in Rome, Exein develops cybersecurity software that embeds directly into connected devices. This device-level approach enables real-time threat detection and response without relying solely on network-level protection. The company’s technology is deployed across more than 1.5 billion devices in sectors such as healthcare, automotive, aerospace and industrial manufacturing.
Exein refers to this approach as building a digital immune system. It is designed to meet rising regulatory expectations, including Europe’s NIS2, Cyber Resilience Act and the US Cyber Trust Mark. The company partners with major OEM and chipset makers such as MediaTek, Supermicro, Kontron, SECO and AAEON.
Gianni Cuozzo, Exein’s Founder and CEO, said the company’s growth reflects the urgent demand to secure devices that are now part of everyday life. He noted that embedded security at the device level is fundamental and that Exein is focused on building the digital immune system for the connected world.
Securing AI systems and preparing for what’s next
Part of the new funding will support the development of runtime security tools for AI infrastructure and large language models. These tools are designed to run directly on edge devices, in response to the growing demand for decentralized AI protection that does not rely on the cloud.
Exein will also pursue acquisitions to strengthen its platform. The goal is to help manufacturers keep pace with evolving security threats while remaining compliant with emerging international regulations.
A changing threat landscape
Balderton Capital, which led the round, is a European venture firm that has backed companies such as Darktrace, Revolut and Depop. Elena Moneta, Principal at Balderton, explained that as more systems become connected, the risks multiply. She pointed out that attackers no longer need to go through obvious entry points and that everyday objects like a microwave on a military ship or a smart fish tank in a hospital could be used to compromise an entire network.
She said Exein addresses this challenge where it starts by embedding real-time security at the device level, capable of monitoring, learning and responding. According to Moneta, the Exein team is well positioned to take on the task of protecting the next generation of AI-enabled, hyper-connected infrastructure.
With this funding, Exein plans to continue growing internationally while advancing its mission to make connected devices more secure by design.
