[Owasp-leaders] Ruling out false positives from vulnerability scans

On this note, the most /*senior*/ AppSec teams or departments that I 
have seen tend to use a /wide variety of tools/ as opposed to depending 
on any one. Even if some tool categories have better false positive 
rates, they all have different coverage. Even the same type of tool 
(from different vendors or foundations) used against the same app have 
widely different coverage in my experience.

So I suggest that instead of throwing one tool or one tool category at 
the problem, throw the kitchen sink at it and more - depending on your 
budget and resources.
