There's an asymmetry in the way we approach security today... The threat takes the form of lots of hackers, with lots of different skill-sets and diverse motivations - And the majority of them aren't being paid by the hour to attack your stuff. Contrast this with the paid by the hour consultants and in-house resources. It's not that the good guys aren't smart, it's that the model is fundamentally disadvantaged. Crowdsourcing security testing through bug bounty programs engages a crowd of "good guys who think like bad guys" and economically incentivizes them the same way the bad guys are.
