INITIAL_SCAN
First scan recorded.
Methodology note: This report reflects a point-in-time automated scan of public infrastructure data — DNS MX records, ASN routing via RIPE Stat API, SSL certificate issuer, and HTML pattern matching against known service signatures. It is not a legal determination of GDPR compliance or any regulatory obligation. Infrastructure can change at any time; the grade reflects configuration at scan timestamp only. Scan data is reproducible. View full methodology →
