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.

Recommendations for ferrybig.nl

Based on this scan, here are the 2 next steps that would most improve security and SEO for ferrybig.nl.

  1. Add 1 missing security header

    Recommended

    ferrybig.nl sends 5 of 6 recommended security headers — missing: Permissions-Policy. Most take one line of server config and protect against clickjacking, MIME sniffing and data leaks.

  2. Add a CAA DNS record

    Nice to have

    ferrybig.nl 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.
