Top issues to fix

6 issues found · 3 high priority

  • Missing Strict-Transport-Security header

    Security

    Add HSTS so browsers always use HTTPS — this closes the protocol-downgrade attack window.

  • Missing Content-Security-Policy header

    Security

    Add a CSP to control which sources can run scripts — the strongest single defense against XSS.

  • Very heavy page (4.9 MB)

    Performance

    Compress images (WebP/AVIF), lazy-load below-the-fold media, and trim unused JavaScript.

  • TLS certificate expires in 22 days

    Security

    Renew soon or enable auto-renewal to avoid a browser-warning outage.

  • Missing X-Content-Type-Options header

    Security

    Add X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.

  • Title longer than 60 characters

    SEO

    Shorten the title to under 60 characters so search results don't truncate it.
