Top issues to fix

8 issues found · 4 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.

  • No H1 heading found

    SEO

    Add exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.

  • Slow estimated load (8.2s)

    Performance

    Use a CDN, enable caching/compression, and cut render-blocking assets — every extra second costs conversions.

  • TLS certificate expires in 17 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.
