Passguard, a cybersecurity startup specialised in monitoring infostealer marketplaces, has successfully raised €500,000 in a pre-seed funding round. Three leading cybersecurity experts and angels are now 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 partner at cybersecurity investor Ctrl+Alt+Invest.

 

 

Scaling the Solution

With the new funding, Passguard aims to further scale its data capabilities and improve accessibility through its API, enabling security integrators to seamlessly provide insights to their clients. Tom Leijte, CEO of Passguard: “With Dimitri, Rogier and Pieter we’re bringing a wealth of cybersecurity experience on board. Their market knowledge and experience in scaling cybersecurity companies will help us move forward. This investment will accelerate our ability to make infostealer intelligence scalable and accessible for organisations across Europe.”

 

The investors highlight both the urgency of the infostealer problem and Passguard’s unique approach:

 

Dimitri van Zantvliet: “Infostealers are currently one of the biggest blind spots in cybersecurity. Passguard addresses this issue in an ethical and accessible way. Made in Holland, and exactly the kind of independent European solution many organisations are looking for.”

 

Rogier Fischer: “Through our collaboration with Passguard I’ve come to know the product and team in depth. Their solution really makes a difference for many companies in the Netherlands and across Europe.

 

Pieter Jansen: “The founders of Passguard combine deep technical expertise with a true entrepreneurial mindset. That makes them a team capable of making a real difference in cybersecurity.”

 

Accelerator Programme

Passguard recently took part in the (Cybersecurity) Validation & Accelerator Programme, organised by YES!Delft, Municipality of the Hague and InnovationQuarter and supported by a.o. HSD. This programme is aimed at fostering the growth of innovative startups and provides a unique opportunity for startups to develop and scale their cybersecurity solutions.
