Security headers4/6
- HSTS
- CSP
- X-Frame-Options
- X-Content-Type-Options
- Referrer-Policy
- Permissions-Policy
Score: 4 of 6 headers present. 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-Age126 days
- PreloadNo
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.
