How this is measured.

Domains are scanned by the Authex Labs scanner. Each scan queries DNS for SPF, DKIM, DMARC, MTA-STS, TLS-RPT, and BIMI. The configured policy and result status are recorded. Each scan produces a posture score out of 100 and a letter grade. Aggregates recompute daily at 04:05 UTC.
