Pages carry more than what you see on screen: comments, hidden fields, keys pasted into the source, files left in public folders. An agent reads all of it. SynthTrail checks for the things that should never be readable.

The scan reads the page as an agent would and looks for live secret keys, cloud access keys, private keys, login tokens, many email addresses in plain view, hidden form fields holding secrets, page comments that mention passwords or tokens, and parts of the page loaded over insecure http.
It also asks your site for common leftovers the way a stranger would: environment files, source-code history, backups and database dumps, server information pages, unlisted data routes and admin areas that open without signing in. A finding is only recorded when real content comes back.
Each finding lists where it was seen, how serious it is, and a plain-language fix, such as removing the file, moving a value to your server or requiring sign-in.
