GuardScan checks HTTP security headers, SSL/TLS certificates, DNS configuration (SPF, DMARC, DNSSEC), and cookie security, then gives you a letter grade from A+ to F with clear explanations for every finding. Beta users get platform-specific fix guides for Nginx, Apache, and Cloudflare, plus PDF reports and scan history. No signup required. Just enter a URL and scan.

Hey Product Hunt! I built GuardScan because I got tired of bouncing between different tools to check basic website security, one for headers, one for SSL, one for DNS records. GuardScan runs all four checks in a single scan and gives you a plain-English report with a letter grade. It's free to use with no signup. Beta users get fix guides with copy-paste instructions for Nginx, Apache, and Cloudflare, plus downloadable PDF reports. I'd love to know: what security checks would you want to see added next?
