Greg van der Gaast

He was one — once named among the world’s most notorious after hacking into a nuclear weapons facility. But while hacking makes for entertaining stories, it doesn’t explain why organisations struggle with security. Greg’s talks do something different. They challenge assumptions, dismantle the status quo, and reframe security as an organisational challenge — not a technical one. That perspective is why audiences from bank chairmen to software vendors consistently describe his sessions as the most eye-opening security talks they’ve ever heard. Security doesn't come from technology, it comes from maximising the effectiveness and quality of an organisation's processes. That means fewer defects (vulnerabilities) to manage, but also more agile and profitable businesses. Using simple, humourous, and memorable analogies, Greg connects equally with everyone, from executives to technical teams, leaving audiences with new clarity — and the confidence to drive real change. Whether you’re educating a board, energising a security team, addressing a conference, or helping vendors sharpen their value, Greg delivers insight that actually sticks. Everyone wants a hacker as a speaker. Greg wishes you didn’t. A different message. Greg takes the audience on a journey, full of easy to understand analogies, about how security can be so much effective and valuable than what it is today. Something that can not only be much better at reducing risks, but doing so in a way that makes perfect business sense. Bolstering companies' efficiency and bottom line rather than weighing on it. All this leaves executives, security professionals, even sales people with powerful new ideas to go forward and achieve more. If you're looking for a security talk that challenges assumptions, resonates beyond the technical audience, and leaves people with ideas they can actually use - let's talk.
