Biggest gaps for Web Hosting & Infrastructure sites

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

HSTS kept for at least a year
53% 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.
Guide: HTTPS and TLS Guide for Website Owners
HTTP/3 advertised
33% observed · all sites 37%
Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
Guide: CDN Guide for Website Owners
security.txt published
37% 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.

No render-blocking scripts in <head>
50% observed · all sites 48%
Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
Guide: Control Third-Party Scripts Before They Control Your Page
CAA records limit who can issue certificates
43% 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.
Guide: HTTPS and TLS Guide for Website Owners
DMARC policy enforces quarantine or reject
63% 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.
