About Greg van der Gaast

Few people are better suited to speak about security than those who have broken through some of the strongest security systems in the world. As a teenager, Greg built a notorious reputation by hacking into a nuclear weapons facility, finding himself a member of the FBI’s ‘Most Wanted’ and being deemed one of the world’s Top 5 Most Infamous Hackers. He then took a step to the other side as an undercover FBI and Department of Defence operative, helping those services crack down on hacker activity.

It’s this early experience that has led to a distinguished 25-year career as an expert in cyber security. Greg is a bestselling author, keynote speaker, and leading voice on the security pillar as a Security Advisor to CDW. He’s passionate about proving that security can be done differently, in a way that brings tangible benefits to customers.

Over his years as a security expert, he’s seen fundamental problems with how security is practised and has made it his mission to see that security problems are treated as quality issues. He focuses on strategies where investment results in cumulative reductions in an organisation’s vulnerability, rather than forever scaling-up imperfect protection around it.
