Fingerprints a domain's cloud infrastructure — DNS records, HTTP headers, a TLS
Fingerprints a domain's cloud infrastructure — DNS records, HTTP headers, a TLS handshake and PTR lookups — to detect CDN, WAF, hosting, DNS and email provider, plus cert issuer/wildcard/SAN count, with confidence scores and a security grade (A–F). Hosts that resolve but answer nothing on 80/443 return http_reachable:false, score null and grade insufficient_data — never a grade inferred from an unanswered probe.
