CheckCyber audits any website's public security posture in seconds. No signup, no install, nothing to configure. 24 checks: TLS certificate and protocols, HTTPS redirection, security headers (HSTS, CSP, X-Frame-Options), cookies, CORS, exposed files (.env, .git, backups), version leaks, script integrity (SRI), vulnerable JS libraries, and DNS/email records (SPF, DMARC, CAA, MTA-STS). Score out of 100, plus the exact fix for each issue (Apache, nginx, WordPress).
