I'm a world-wide security evangelist, meaning I write and speak about hackers, cryptography, fraud, malware and all that interesting stuff.

I've spoken at over 30 conferences on all six developed continents. Some of my favorite engagements were speaking at RSA Europe in Amsterdam, InfoSec in London and Gartner Data Center in Las Vegas

I write a bi-weekly column at SecurityWeek, and have had the good fortune to write for DarkReading and SC Magazine and Network World.

I'm a fly-fisherman, a baseball fan and a craft beer enthusiast.
