HTTPS availability

The site is reachable over HTTPS.

Why it matters: HTTPS encrypts traffic and protects user data.

HTTP to HTTPS redirect

No redirect from HTTP to HTTPS was detected.

How to fix: Configure your server (Nginx, Apache, or host) to 301/302 redirect http:// to https://.

Security headers3/6

  • HSTS
  • CSP
  • X-Frame-Options
  • X-Content-Type-Options
  • Referrer-Policy — sent, but weakSent as "no-referrer-when-downgrade", which sends the full URL — path and query — to other sites. Browsers already default to strict-origin-when-cross-origin when no header is set — use that or no-referrer.
  • Permissions-Policy

Score: 3 of 6 headers effective. For the grade factor (5 pts), 4+ headers and Content-Security-Policy (CSP) are both required. We count a header only when its value actually provides the protection, so a header sent with a weak value counts as “sent, but weak” rather than present. Scanners that count a header as present regardless of its value will report a higher number here.

HSTS (HTTP Strict Transport Security)Enabled

  • EnabledYes
  • Max-Age365 days
  • PreloadNo
Submit or verify on hstspreload.org

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/3 (QUIC)

Not advertised

The server does not advertise HTTP/3 (QUIC) via the Alt-Svc header.

No CAA records. Any CA can issue certificates. Consider adding CAA to restrict issuance.

Redirect chain1211ms total

When you visit the site over HTTP, the server may send you through one or more redirects until you land on the final HTTPS URL. Shorter chains are faster and better for SEO.

Recommendations for saintisidore.org

Based on this scan, here are the 5 next steps that would most improve security and SEO for saintisidore.org.

  1. Set up an HTTP → HTTPS redirect

    High impact

    saintisidore.org does not redirect plain HTTP requests to HTTPS. Visitors (and search engines) landing on the HTTP version get an insecure page, and you may be splitting SEO signals between two versions of the site. A single 301 redirect fixes both.

    How to fix HTTP to HTTPS redirect Re-test the redirect

  2. Fix the SSL certificate

    High impact

    The certificate for saintisidore.org is expired. Browsers show a full-page warning for invalid certificates, which drives most visitors away immediately.

  3. Add 3 missing security headers

    Recommended

    saintisidore.org sends 3 of 6 recommended security headers — missing: CSP, Referrer-Policy, Permissions-Policy. Most take one line of server config and protect against clickjacking, MIME sniffing and data leaks.

    How to set security headers What each header does

  4. Consider HTTP/3

    Nice to have

    saintisidore.org supports HTTP/2 but does not advertise HTTP/3 (QUIC). HTTP/3 improves performance on lossy mobile networks. If you are behind Cloudflare or a modern CDN it is usually a toggle.

    How to enable HTTP/2 and HTTP/3 Why HTTP/3 detection tools disagree

  5. Add a CAA DNS record

    Nice to have

    saintisidore.org has no CAA record, so any certificate authority can issue certificates for it. A CAA record limits issuance to the CAs you actually use — a cheap defense against mis-issuance.
