"Greg had a great story to tell – it sounded like the script to a Hollywood movie. He gave the audience plenty to think about as he told his amusing tale of misspent youth to a top tech consultant. For security professionals and those who just want to look at problems from a different perspective, Greg gave us food for thought."

Keynote by Greg van der Gaast:
Exposing the Leadership Crisis in Cybersecurity
Who’s really leading your cybersecurity efforts and are they truly accountable?
In many organizations, cybersecurity leadership exists in a fog of ambiguity: unclear roles, unchecked performance, and paradoxical rewards for failure. It’s a system that breeds dysfunction, erodes trust, and wastes potential.
Keynote speaker Greg van der Gaast exposes this leadership gap with striking clarity and more importantly, offers a path forward. In his powerful keynotes, Greg reveals how a lack of direction and accountability undermines security from within, and how redefining leadership around integrity, clarity, and purpose can turn things around.

Book Greg van der Gaast for your event to challenge your assumptions and spark real change where it’s needed most, at the top. Because without true leadership, security is just theatre.
Keynote by Greg van der Gaast:
Rethinking Sustainability: Efficiency Over Illusion
Is your sustainability strategy truly helping the planet, or just ticking boxes?

In his provocative keynote on sustainability, he challenges status quo thinking and exposes the uncomfortable truths behind today’s “eco” efforts. His focus? Practical efficiency, systemic waste reduction, and smarter choices that benefit both the planet and your bottom line.
