Biggest gaps for Stock Image & Video Libraries sites

The checks with the most room to improve, weighted by impact.

  1. HSTS kept for at least a year

    30% observed · all sites 34%

    Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

  2. CAA records limit who can issue certificates

    12% observed · all sites 13%

    Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.

  3. DMARC policy enforces quarantine or reject

    42% observed · all sites 39%

    Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.

  4. Modern image formats in use

    46% observed · all sites 40%

    Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.

  5. Content Security Policy present

    21% observed · all sites 32%

    Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.

  6. security.txt published

    25% observed · all sites 7.1%

    Publish /.well-known/security.txt with at least Contact and Expires fields, as RFC 9116 requires, and review it before it expires.
