Italy’s Cybersecurity Firm Exein Raises €100M To Fuel Global Expansion

The round was led by Blue Cloud Ventures, with participation from HV Capital, Intrepid Growth Partners, Geodesic Capital, and J.P. Morgan.

Gianni Cuozzo, founder and CEO, Exein, says: “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.”

In the context of cybersecurity and adjacent security technologies, Exein’s extension round stands out for its scale. Most funding announcements this year in the sector have been early-stage and considerably smaller.

For example, XFA in Antwerp raised €1.5 million to tackle emerging workplace cybersecurity risks; Equixly in Verona secured €10 million in Series A funding to scale its AI-driven API security testing platform, adding another Italian player to the cybersecurity landscape; and Paris-based Evertrust raised €10 million to expand its digital trust and PKI offering.

On the early-stage end, Zurich-based Soverli raised €2.2 million in pre-Seed funding, Ireland's Mirror Security secured €2.1 million in pre-Seed funding, and Lithuanian startup CBRX raised €540k in pre-Seed funding. These reflect continued investor interest in specialized niches like sovereign mobile security, encrypted AI and cloud-based cybersecurity tools.

In total, these rounds account for approximately €28 million in disclosed funding in 2025, excluding Exein itself.

Following its earlier €70 million Series C round in July 2025, Exein’s latest raise places it at the top of the funding distribution for European cybersecurity this year.

“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 the first wave of this breakthrough at RSAC in Q1, as we continue building the digital immune system that will protect the connected world for years to come,” adds Cuozzo.

Founded in 2018 Exein provides AI-powered runtime protection directly inside device software, securing more than 1.5 billion devices across critical sectors including industrial automation, automotive, energy, healthcare, semiconductors, aerospace and robotics.

Exein’s growth reflects the increasing threat of cyberattacks and a shift toward securing connected devices at the source, rather than relying on conventional perimeter defenses.

By the first quarter of 2026, Exein expects the number of devices running its software to surpass two billion, as it rolls out new technology and faces growing regulatory pressure for device-level security.

Rami Rahal, Founder and Managing Partner at Blue Cloud Ventures, says: “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.”
