Biggest gaps for Telecommunications & Internet sites

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

  1. Static files cached for 30 days or more

    41% observed · all sites 51%

    Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.

  2. HTTP/3 advertised

    13% observed · all sites 37%

    Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.

  3. security.txt published

    13% 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.

  4. CAA records limit who can issue certificates

    15% 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.

  5. HSTS kept for at least a year

    54% 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.

  6. No render-blocking scripts in <head>

    37% 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.
