Q - How does Compliance Sheriff work?
A - Compliance Sheriff is a 'web application', that scans 'web content' through a 'web session' directly from the server. It's a 'presentation layer' tool that will apply rules (checkpoints) to pages that it lands on.
Its an enterprise class solution that can automatically crawl through hundreds or even thousands of pages with each scan, and will pinpoint each issue found with a "rendered view" and "code source view".
Depending on which modules are purchased (Accessibility, Site Quality, Privacy, etc) , there will be many OOTB checkpoint groups that come preloaded such as Section 508, WCAG 2.0 A, PII and PFI, Link Validation, Spell Checking, and so on. But essentially, Compliance Sheriff is a very transparent, highly customizable "data gathering" tool that can scan web content for just about anything!
