I have a long standing bug-bear over the uselessness that security vendors seem to bring to cons in ZA. They respond to requests for "please don't pitch your product" by talking generically about the "outsourced next generation cloud-based firewall industry" as if that was some sort of legitimate field that didn't constitute only their product. They still send sales/pre-sales/product specialists with their EMEA marketing deck, rather than something of actual value. But as long as they're offering money, people take it, no questions asked. You'd think the empty rooms and people walking out of their presentations would send the message, but instead a local distributor finds a new vendor, or the vendor sends a new person, so the lesson is never learned.
That's not why Matt suggested the bingo, but it's one of the main reason's I helped. I want the vendor telling us that their product will block 100% of APTs to walk away feeling dirty and ashamed, and maybe even realise the error of their ways and turn into the next Charlie Miller. Also, I want to help Johnny, and the great work HFC is doing in Uganda (and Kenya).
So, as Matt already said. Find either he or I at the security summit (we'll be wearing I Hack Charities shirts) and give us R50 (or more, it's for a good cause) and we'll give you a security vendor bingo card (feel free to pre-print yours). Fill it out during the talks or on the con floor, optionally with the name of the vendor so we can tally a highscore list, then either return it to us in person, or mail it to the address printed on it, and we'll give you the results. There'll be some sort of prize if we can muster one, one for the person to complete first with the highest score, and one for the person who comes up with the best "other" phrase. Given that you could just tick them all off and give yourself a first high score, this will be a "Don't be a Douche" style contest.
