HTTPS availability

The site is reachable over HTTPS.

Why it matters: HTTPS encrypts traffic and protects user data.

HTTP to HTTPS redirect

Requests to HTTP are redirected to HTTPS.

TLS & CertificateB+

Redirects to www.facebook.com — same certificate covers both hosts.

ValidYes
IssuerC=US, O=DigiCert Inc, CN=DigiCert Global G2 TLS RSA SHA256 2020 CA1
Expires2026-08-19
Days until expiry7 days

Why it matters: A valid, non-expired certificate ensures encryption is trusted by browsers.

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)Preload ready

  • EnabledYes
  • Max-Age180 days
  • PreloadYes
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.

Recommendations for facebook.com

Based on this scan, here are the 3 next steps that would most improve security and SEO for facebook.com.

  1. Certificate expires in 7 days

    High impact

    Renew the certificate for facebook.com before it expires to avoid downtime. If you use Let's Encrypt or another ACME CA, check that auto-renewal is actually running — expired-but-automated certs are one of the most common outages.

  2. Add 1 missing security header

    Recommended

    facebook.com sends 5 of 6 recommended security headers — missing: Referrer-Policy. Most take one line of server config and protect against clickjacking, MIME sniffing and data leaks.

  3. Disable TLS 1.0 and 1.1

    Recommended

    facebook.com still accepts TLS 1.0 and/or TLS 1.1. Modern browsers have removed those versions; leaving them on costs grade points and fails many compliance scans. Restrict the server to TLS 1.2 and 1.3.
