Show HN: DefendFlow Domain Security Board – live scans of popular sites

riyao_lin Sunday, January 18, 2026

Hi HN!

We built a lightweight public board that continuously scans popular domains for security posture (headers, DNS/email security, cert status, findings) and updates hourly.

It’s free to browse, and you can request a domain to be scanned in the next batch. The board is powered by our Radar scanner service, which provides the full report and ongoing monitoring.

Demo: https://domain-security-board.defendflow.xyz Full reports/monitoring: https://radar.defendflow.xyz

We’d love feedback on the UI, the scan coverage, and what signals would be most useful to add next.
