Once named one of the World’s Top 5 Most Notorious Hackers after breaking into a nuclear weapons facility and then working covertly for the US DoD and FBI for a number of years, Greg van der Gaast is not short of humorous and engaging stories. More importantly, his simple yet powerful anecdotes have captivated audiences from security practitioners to boardroom executives.
He is the best-Selling Author of “Rethinking InfoSec” and “What We Call Security”, a former CISO and Chief Technologist at the world’s largest VAR. His 25-year career has led him to being the Managing Director of Sequoia Consulting where he helps transform security from being a growing cost-centre that chases evermore risk, to a streamlining quality function that helps organisations drive risk and cost out of their business.
Whether it’s helping businesses achieve more from their security investments, providing vendors with powerful new narratives, or just entertaining and enlightening audiences with refreshing ideas, Greg has proven himself to be one of the most engaging and thought-provoking security speakers on the circuit.

Official Feedback from In-Person & Virtual Events
Feedback from In-Person Events:
"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." - Jamie, Learning Programme Manager, Ministry of Defence
"Greg is an inspirational leader. His principle of information security being a quality function across all areas of the business allows for not just risk reduction, but organisational improvement and cost savings that ultimately lead to better products and services, and happy customers. Greg doesn't just think at the departmental level, he understands and considers every aspect of business, company culture and customer needs." - Mike, Information Security Manager, Scoutbee

"Greg had a great grasp of the industry we operate in and extensive knowledge to share. He presented incredibly well, in a way we could all understand. For future years we would want someone a little more energetic and more high level in terms of content for an opening keynote, but for the time he had to create his presentation he did an exceptional job." - Katherine, Senior Global Events Manager, Ingram Micro
