Powered by sentinel-mcp.

Enter any URL and get a live security report card in seconds. PagePulse streams results in real time as each scan completes:

| Scan | What it checks | |---|---| | HTTP Security Headers | HSTS, CSP, X-Frame-Options, and 7+ more headers — graded A+ to F | | SSL/TLS Certificate | Cert validity, expiry, trust chain, protocol version, cipher strength | | DNS & Email Security | SPF, DMARC, DKIM, CAA records — flags email spoofing risk | | Technology Fingerprint | Detects web servers, frameworks, CMS, CDN/WAF from headers + HTML | | Port Scan | 30 high-risk ports checked, flags exposed databases/RDP/Telnet |

Results include an overall grade, critical findings, MITRE ATT&CK mapping, and per-category score breakdowns.
