I hereby declare the second-best ad at RSA:
"Beware of False Positives"
(I give "best" to my company's own ad, of course. It holds special place in my heart. However, if you think this one is first place, and ours only second, I'll forgive you.)
The woman working the booth tells me that it was "obtained" in Seattle, and is authentic. They were raffling it off in their booth. Excellent job CyberDefender.
