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.

My Memoirs...

May 1, 1986 

Like a Rolling Stone

I discovered two things at age 16, and one of them was Vodka. My parents had a pretty permissive philosophy about raising children – my father told me that as long as I got good grades, I could pretty much do whatever I wanted, provided I “didn’t bring it home.” Discretion, as it were.

National ID Systems and Data Privacy

After receiving some media inquiries around the Philippines national ID system, I put together an essay, with the help of my indispensible personal assistant in the islands, on data privacy and the Philippine National ID system (PhilSys). Back End Systems quoted me from the essay in this article, but I'm hoping that the original gets reprinted somewhere else, because it was pretty good!

F5Agility18: Application security and evolving threats

Here's a video interview done by none other than F5's Calvin Rowland himself. He and I are both 17-year veterans of F5 Networks, and we're both good (or at least energetic) on video. He's interviewing me for our Agility Live series, and I'm discussing some of our security research at F5 labs.

David Holmes: On the trade-off between security and convenience in technology

Bucket list item achieved. I was interviewed on live TV in the Philippines on the ANC Early Edition news program about consumer internet safety and how Filipinos view it through the lens of convenience vs. security. There were likely millions of people watching and you'd think one would be nervous but it was just so much! Would do it again :)
