Security headers5/6

  • HSTS
  • CSP
  • X-Frame-Options
  • X-Content-Type-Options
  • Referrer-Policy
  • Permissions-Policy

Score: 5 of 6 headers effective. For the grade factor (5 pts), 4+ headers and Content-Security-Policy (CSP) are both required.

Cache-Control includes no-store on the HTML response. Browsers will not cache the document; ETag and conditional requests (304) are effectively disabled. Often intentional for authenticated pages; for public pages consider private with max-age or removing no-store if you want HTTP caching.

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.
