■ Challenge detected

Live technical checks of a domain, measured by us at request time: A/AAAA, NS, MX records, SPF and DMARC policies, DNSSEC presence (DS), CAA, TLS certificate issuer, validity dates and hostname match on port 443, and HTTPS security headers (HSTS, CSP, X-Frame-Options). Returns a simple risk flag list. Use when an agent must sanity-check a company's or vendor's domain before trusting an email, link or supplier: does it resolve, receive mail, publish SPF/DMARC, and serve a valid TLS certificate.
