Website security monitoring — with the fix attached

CompleteStatus continuously grades your HTTP security headers A+ to F, watches your TLS certificates and DNS records, and — uniquely — hands you the exact copy-paste fix for every finding. It is website security monitoring that closes the loop, not just another scanner that tells you something is wrong.

How it works

From zero to watched in four steps.

Add your URL

Point a monitor at any public site — no agent, no code change.

Get graded

CompleteStatus scores every response header and cert, and opens a findings inbox ranked by severity.

Paste the fix

Each finding ships the exact config snippet for your server. Deploy it and re-scan to confirm the grade lifts.

Stay watched

Re-scans run continuously and alert you if a header disappears or a cert nears expiry.
