Greg van der Gaast
Greg van der Gaast is one of the world’s most recognised voices in cybersecurity and one of its most unlikely. Once deemed among the world’s top five most infamous hackers and placed on the FBI’s most-wanted list, Greg has since turned his expertise into a force for good, working as an undercover FBI and DoD operative before building a distinguished 25-year career as a CISO, security architect and strategic advisor to global organisations.
Author of the bestselling What We Call Security and Rethinking InfoSec, Greg is renowned for his business-focused, no-nonsense approach to security - challenging organisations to treat security not as a cost centre, but as a fundamental quality issue that drives real business value.
