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.

They call me the "one-take wonder" in the studio, because I've done so many videos that I just do it in one take anymore.

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

However, he also explains that Internet security cannot be regulated like other manufacturing processes. Increasing awareness among users could also help resolve this issue, with the IoT Defense scanner being a small step in this direction.
