Gorilla Capital invests in SensorFu

Gorilla Capital Fund III has made its 56th investment in SensorFu — a cybersecurity company that prevents critical systems from being exposed to the internet.

Organizations operating critical infrastructure and high-security environments rely on their systems being fully separated from the internet. These systems control essential operations and are designed to stay closed.

The problem is that over time, this separation can break without anyone noticing. Systems change, configurations evolve, and small, unintended connections can appear. Even a single unnoticed pathway to the internet can expose critical systems to external threats. This is not a theoretical risk. In environments such as industrial control systems, automation networks, and national defence systems, even a small exposure can have serious consequences.

SensorFu addresses this challenge with its product Beacon. Beacon continuously monitors networks and proactively detects any unintended paths to the internet. Instead of relying on occasional checks, organizations can monitor their systems at all times and react immediately if something changes.

The solution is used by organizations operating in demanding environments, including TenneT GmbH, Veolia, and Synopsys, as well as utilities, manufacturing companies, and government organizations across Europe and the United States.

The new funding will support SensorFu’s entry into new markets and further development of its product, helping more organizations prevent critical systems from being exposed.

“Organizations assume their critical systems are separated from the internet, but over time that assumption can drift away from reality,” says Mikko Kenttälä, co-founder and CEO of SensorFu. “We want to help those who build and maintain organizations’ most critical networks and systems continuously verifey that their most important cybersecurity policies remain in place –and enable them to react quicly is something goes wrong. Gorilla Capital’s approach to building companies fits well with how we think about developing both the product and the business — through continuous learning and staying close to real customer environments.”

“SensorFu has built its product around a clear and critical need, and the team has demonstrated this value with demanding customers,” says Risto Rautakorpi, Partner at Gorilla Capital. “Their disciplined, hands-on approach and deep domain understanding create a strong foundation for consistent progress. We value how the team stays close to real-world environments and turns that learning into practical product development.”

We are pleased to partner with Nordic Option, Korpun Siemen, and a group of experienced angel investors.
