There's a substantial counterargument to this I need to type up. I understand where you're coming from as someone who once ran a consultancy, Tom, but from the perspective of someone who hires security firms and consumes their services—and this is essentially a TL;DR for the opinion I need to flesh out here—we don't do it because we trust. We do it out of necessity.

TODO: Bryant to flesh this out in between laundry rounds tonight.
