After 34 years fighting malware, Mikko Hypponen joined anti-drone company Sensofusion as Chief Research Officer and part-owner, a move that anticipated the collision of cyber and physical security.
Mikko Hypponen, the Finnish cybersecurity expert who spent three decades fighting malware, is now Chief Research Officer and part-owner of Sensofusion, an anti-drone company planning one of Europe’s most closely watched IPOs.
After a 34-year career at F-Secure and WithSecure, his move to counter-drone technology in 2025 puzzled some observers. The reason is now becoming clear: the company he helped push to the center of the drone-defense conversation is heading for a Helsinki listing, and the story behind it says a great deal about where security, technology, and defense are converging.
What Sensofusion does, and why it matters now
Sensofusion is a Finnish company that builds systems to detect, locate, and neutralize drones. Its flagship product, Airfence, is used by militaries, law enforcement, and critical-infrastructure operators worldwide to protect airspace from unmanned threats. The timing of its rise is not coincidental.
Drones have become one of the defining weapons of modern conflict, and demand for reliable counter-drone technology has climbed sharply as governments and companies confront a threat that is cheap to launch and hard to stop.
This is precisely the shift Hypponen anticipated when he made the move: as he has put it, fighting drones is not so different from fighting malware, both are a cat-and-mouse game against a fast-evolving adversary.
It is the same convergence of digital and physical systems now reshaping robotics, which we explore in our look at Sebastian Thrun’s new robotics venture.
The IPO: a Helsinki listing on the horizon
According to reporting in the Finnish financial press, Sensofusion is planning an initial public offering on the Helsinki Stock Exchange, targeted for as early as December 2026.
The company’s trajectory helps explain the interest: its revenue has tripled over three years to roughly 21 million euros, and a recent funding round of around 45 million euros gave it a post-money valuation in the region of 595 million euros.
It has also expanded through acquisition, adding Finnish aircraft manufacturer Atol Aviation to extend its surveillance capabilities.
For a company operating in Ukraine, the United States, Canada, and beyond, an IPO would mark a significant step from specialist defense supplier to publicly traded player in one of the fastest-growing corners of the security market. As with any planned offering, timing and terms may shift, but the direction of travel is unmistakable.
Why Hypponen’s move was a signal, not a departure
Hypponen spent 34 years at F-Secure and later WithSecure, where as Chief Research Officer he investigated some of the most consequential cyber incidents in history, from the Sasser worm to Stuxnet. His decision to join Sensofusion was widely read as a pivot, but it is better understood as a continuation.
His central insight, captured in what is known as Hypponen’s Law, is that whenever a device is described as “smart,” it is vulnerable. Drones are exactly that: connected, autonomous, increasingly intelligent systems that can be defended against or turned into weapons.
His shift from software threats to physical-world threats mirrors the broader collapse of the boundary between digital and physical security, and it builds directly on the three decades of work covered in our feature on why Hypponen is one of the world’s leading voices on cybersecurity and AI threats.
What this means for events and audiences
For organizations planning conferences and leadership events, the Sensofusion story gives Hypponen a timely new dimension. He is no longer only a voice explaining cyber threats; he is an operator at the intersection of cybersecurity, drone defense, and the business of security itself.
That makes him valuable to a wider set of audiences, from technology and cybersecurity events to conferences on defense, critical infrastructure, and geopolitical risk. His perspective connects naturally to the questions boards are asking about physical security and supply-chain resilience, themes we examine in our analysis of supply chain weaponization.
Audiences leave with a clearer sense of how the threats of the next decade will move fluidly between the digital and the physical, and what it takes to stay ahead of them.
