Website Security Check
Passive security audit of any public website — TLS versions & certificate, security headers & CSP grading, 50+ exposed-file checks, admin panels, cookies, email security (SPF, DKIM, DMARC, MTA-STS), blocklists, subdomains from CT logs, WHOIS, hosting and technology — with copy-paste fixes and an AI summary. No exploitation, no payloads.
Passive checks only — no exploitation. Active testing requires written authorization.
