What does the public internet say about your site?

Fourteen checks anyone could run and almost nobody does: how your site handles transport security, what a browser is allowed to load, whether someone else can send email as your domain. AI runs the checks in seconds; the fixes that follow are owned by named engineers.

Passive only: we read public responses and DNS records. We never log in, submit anything, test any input, or put load on your site.
