Leusden, 10 September 2025 – Passguard, specialized in monitoring infostealer marketplaces, has brought three leading cybersecurity experts on board as investors: Dimitri van Zantvliet, Cybersecurity Director at Nederlandse Spoorwegen (Dutch Railways), Rogier Fischer, founder and CEO of Hadrian, and Pieter Jansen, founder and former CEO of Cybersprint and currently a partner at cybersecurity investor Ctrl+Alt+Invest. With the participation of these experts and several other angels, Passguard raised a total of half a million euros.
For Dimitri van Zantvliet, Passguard’s focus was decisive:
“Infostealers are currently one of the biggest blind spots in cybersecurity. Passguard addresses this problem in an ethical and accessible way. It’s made in Holland—exactly the kind of independent European solutions many organizations are looking for.”
Rogier Fischer already knows Passguard as a supplier through Hadrian:
“Through our collaboration with Passguard, I got to know the product and team in depth. I’ve seen that their solution truly makes a difference for many companies in the Netherlands and across Europe.”
Pieter Jansen followed the founding team closely during a coaching program as part of the Cyber Program at startup incubator YES!Delft:
“Passguard’s founders combine deep technical expertise with a true entrepreneurial mindset. That makes them a team capable of moving the needle in cybersecurity.”
Tom Leijte, CEO of Passguard, concludes: “With Dimitri, Rogier, and Pieter we’re bringing a wealth of cybersecurity experience on board. Their market knowledge and experience scaling cybersecurity companies will help us move forward. With this funding, we’re investing in making our data scalable and accessible via our API, so that security integrators can deploy it directly for their customers.”
