Top issues to fix

8 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.

  • 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.

  • Missing X-Content-Type-Options header

    Security

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

  • Missing X-Frame-Options header

    Security

    Add X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.

  • robots.txt not found

    SEO

    Publish /robots.txt with a Sitemap: directive to guide crawlers.
