Stepping up a gear with our new CEO Alex Driesen

Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

SUMMARY

  • AI breaks “classic” secure-by-design: risks keep shifting after deployment due to updates, reuse, and unpredictable behavior.

  • The problem is control, not detection: a threat modeling report often leads to fragmented follow-up and unclear ownership.

  • Secure-by-design for AI must be continuous: sustained accountability, tracking, and visibility into residual risk across the full lifecycle.

  • AI-rich companies hit the wall first: scale, key-person risk, and audit pressure make one-off reviews unsustainable.

  • Toreon makes it actionable with AI threat modeling: we pinpoint AI-specific vulnerabilities as the starting point for focused mitigation and provable compliance.

As of April 12, Alex Driesen will become the new CEO of Toreon. He takes over from Sebastien Deleersnyder, who now takes on the role of CTO. Alex Driesen earned his stripes at Zetes and more recently at Nallian. In his new position, he will be responsible for the further expansion and professionalization of Toreon’s services.

“As a board member, I have come to know Toreon as a wonderful company with highly motivated staff, progressive customers and ambitious shareholders. Moreover, in seven years Toreon has already established a very nice track record in a booming and socially very relevant sector. So, when the owners asked me to join them, I didn’t hesitate for a moment,” says Driesen.

Long-time partner

The new CEO Alex Driesen knows the company and the three founding managers well. As an independent board member for three years, he kept a close eye on Toreon’s progress. With Driesen, Toreon brings decades of international senior management experience at growth companies in the broader technology sector, both at established companies and startups/scaleups and at both product and service companies.

“Alex has done a fantastic job guiding Toreon over the past few years as an external board member and is partly responsible for where we are today. I am confident that he will do the same in his role as CEO,” says Sebastien Deleersnyder.
