- The sample report separates new, fixed, and changed findings, and gives a specific record or setting to address.
Field notes
The page describes checks based on public DNS, certificate logs, pages already served to visitors, and public datasets; it says the audits do not attack systems or probe private paths. Its fictional sample report includes a stale certificate, a subdomain pointing to an unclaimed GitHub Pages site, and look-alike registrations. The sample says 29 checks ran, while the site separately advertises 39 checks overall.
