Where the answer comes from

Source and scope

Detection reads the response headers, cookies and HTML of the single page supplied, as the Attest fetcher received it. It is not a security audit or a vulnerability scan.

Attest reports what it read, with the source it read it from. It is general information, not advice, and not a legal record.
