Named one of the world's 5 most notorious hackers, former US Gov't operative, CISO, author, and a very different kind of security speaker.
Everyone seems to want a hacker as a speaker. Greg wishes you didn't.
He was one, even once called one of the world's most notorious, and he'll be the first to tell you don't get the skills needed to secure an organisation from being a hacker (but it does give you some entertaining stories!
If, however, you want something completely different from a security talk, something thought-provoking, pragmatic, hard hitting, that completely shatters the status quo, look no further.
Greg presents radical concepts around security in simple, impactful, and often amusing anecdotes that not only make perfect sense to technical and executive audiences alike, often leaving them stunned with unexpected realisations and ready to drive real change with powerful new ideas.
It's no wonder he's more often than not rated the top speaker at the events he participates in.
Whether you want to entertain and educate your board, your IT and Security teams, the audience of a security conference, or are a vendor looking for new value propositions to beat the competition, Greg is your man.
Thought-Provoking for Every Audience


Greg got his start in security as a teenager who hacked a nuclear weapons facility and went on to work covertly for the US government.
He is frequently sought out for this background as an expert in security, but Greg is adament that these skills are of little value to securing an organisation; organisations are not computers.
Instead Greg shares thought-provoking insights he's learned since on how to achieve the outcome of security, highly effective approaches that the security industry remains silent on.
Greg takes the audience on a journey, full of easy to understand analogies, about how security can be so much more and more effective than what it is today. Something that can not only be much better at reducing risks, but doing so in a way that bolsters the company's 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 do better.
