Dimitri van Zantvliet is an accomplished leader in information security currently serving as the CISO of Dutch Railways (Nederlandse Spoorwegen). Dimitri is at the forefront of protecting one of the Netherlands’ most vital transportation networks against an ever-evolving landscape of cyber threats.

His leadership has been instrumental in addressing the unique challenges of securing critical infrastructure in an era marked by hybrid warfare and complex geopolitical dynamics. Known for his bold and innovative perspectives, Dimitri emphasizes in this podcast that the “C” in CISO stands for Change—highlighting the role of security leaders as agents of transformation within organizations.

He is a sought-after speaker and thought leader, sharing insights on topics such as hybrid warfare, OT security, and the future of cybersecurity leadership.
