A European cloud: sovereign or illusion? With Joey van den Heuvel (A.S.R.)
The discussion about a "European cloud" seems endless. Everyone wants more digital sovereignty, yet meanwhile half of our infrastructure still runs on American technology.
In this episode of CyberGrowth by Gruzzy I talk with Joey van den Heuvel of A.S.R. Verzekeringen.
Joey spent years as an IT Security Officer and recently became Product Owner Cloud — exactly the person to ask how realistic that idea of a European cloud actually is.
We talk about the risks of blind trust in cloud providers, the role of politics and business, and why full sovereignty may be more dream than reality.
A conversation about technology, governance, money, and the limits of independence. (In Dutch.)
Risk quantification — the future of risk management? With Paul Permentier and Lars van Zijl of Polar Risk
In this episode of CyberGrowth by Gruzzy we talk with Lars van Zijl and Paul Permentier, founders of Polar Risk. Their mission: helping organizations make risk truly measurable through risk quantification.
We discuss what risk quantification actually involves, why so many companies still wrestle with 'risks in color codes', and how a quantitative approach helps you make better decisions about security investments.
Lars and Paul share how their experience at large organizations brought them to this point, what benefits it delivers for both CISOs and boards, and why they believe it's the future of risk management in cybersecurity.
This episode is packed with practical examples, sharp insights, and a fresh look at making risk concrete — not just on paper, but in hard numbers that convince the business. (In Dutch.)
Chat Control — digital protection or mass surveillance? With Jort Kollerie
In this episode of CyberGrowth by Gruzzy we talk with Jort Kollerie, specialist at Orange Cyberdefense. Together we dive into the EU's controversial proposal: Chat Control.
We discuss what the plan involves, why it has such a big impact on our privacy and safety, and what risks arise when end-to-end encryption is weakened. Jort explains why this proposal may be well-intentioned, but in practice leads to mass surveillance and greater vulnerability for everyone.
This episode is full of sharp insights, honest criticism, and clear arguments for why we — as a sector ánd as a society — should speak out against Chat Control.

In this episode of CyberGrowth by Gruzzy we dive into the world of secure development together with Carlo Klerk. How do you make security an integral part of your development process, and how do you keep management and development on the same page?

The ideal project? With Maikel Roolvink of Brandaris Cybersecurity
The reality of some projects can't be predicted in advance, and sometimes the challenge isn't in how to respond, but in the foundation of the policy itself. But how do you find that out?
In this episode we dive in with Maikel Roolvink: how do you identify the ideal security project, what can you run into, and how do you handle different scenarios? He takes us through the do's & don'ts he encountered in his 15 years of experience and how to deal with them successfully! (In Dutch.)
Cyberwarfare — with Tamara Hendriksen and Jort Kollerie of Orange Cyberdefense
On this podcast we regularly talk about hackers. Often groups with criminal intent, after money and data, with companies and individuals as victims.
But plenty is happening at the international level too. Many countries have their own divisions of hackers to obstruct their geopolitical opponents, steal information, or improve their own position in the world.
But who are these so-called 'state actors'? How do they operate? How are they organized?
That's what I discuss in episode 9 with Tamara Hendriksen and Jort Kollerie of Orange Cyberdefense. They've recently researched these countries and will tell you how it all fits together.
Enjoy! (In Dutch.)
OT security: the neglected child? With Fred Streefland of Secior
By now we're all familiar with IT security — Information Technology security.
What many people don't know, however, is that there's another kind of security: OT, or Operational Technology.
At least as important a field, but far less known. Why is that? And what exactly is it?
What consequences can it have when your OT security isn't in order?
That's what I discuss in this episode with Fred Streefland, CEO of Secior. Secior specializes in securing OT environments.

Help! I want to become an IT security freelancer! With Paul Permentier
Plenty of information security and IT security specialists have thought about it at some point: shouldn't I start my own business?
But how do you do that? What's involved? How do you find your assignments? And what are the pros and cons?
Great questions to put to Paul Permentier! He started freelancing 9 months ago, so it's all still fresh in his memory.
Enjoy watching and listening! (In Dutch.)
What did information security look like 20 years ago? With Bert Heitink
With 2.5 years of experience in information security, I'm still a rookie in the field. But I'm very curious about how things were done years ago.
What are the biggest differences and similarities?
What lessons can we learn from the past?
In this podcast I talk about that with Bert Heitink, who has worked in the Dutch IT security industry for more than 20 years. He takes us through his career and paints a picture of how things developed over the years.

Certification: why, and where do I start? With Antonio Chan of Indiciatech
You can demonstrate that you think about your information security with a certificate. But that doesn't necessarily mean you're actually secure.
And there are so many of them — which ones do you need?
In this podcast I talk with Antonio Chan. He knows exactly which certification you need and when, but above all what you need to do to make your organization secure.
He shares practical tips for not just demonstrating that you've thought about it, but also for taking the first steps toward a solid information security policy. (In Dutch.)
