- HSTS
- CSP
- X-Frame-Options
- X-Content-Type-Options
- Referrer-Policy
- Permissions-Policy
Score: 4 of 6 headers present. For the grade factor (5 pts), 4+ headers and Content-Security-Policy (CSP) are both required.
HSTS (HTTP Strict Transport Security)Preload ready
- EnabledYes
- Max-Age365 days
- PreloadYes
Why it matters: HSTS tells browsers to use only HTTPS for this site. Preload allows inclusion in browsers’ built-in HSTS lists.
We check Chromium’s built-in list. hstspreload.org checks eligibility for submission (HSTS header, redirect chain). Results may differ for domains that are preloaded but no longer meet current eligibility rules.
HTTP/2
Negotiated (ALPN h2)
ALPN: h2
HTTP/3 (QUIC)
Advertised (not negotiated)
Alt-Svc: h3=":443"; ma=86400
Advertised via Alt-Svc, but an active HTTP/3 request fell back (server did not serve h3 on UDP 443).

No CAA records. Any CA can issue certificates. Consider adding CAA to restrict issuance.
Mixed content
None detected
No HTTP resources were detected on the HTTPS page.

Add 2 missing security headers
