Top issues to fix

9 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.

  • Slow estimated load (4.4s)

    Performance

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

  • 2 cookies without Secure/HttpOnly flags

    Security

    Set Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.

  • Meta description longer than 160 characters

    SEO

    Trim the meta description to under 160 characters to avoid truncation in search results.

  • Missing canonical link

    SEO

    Add <link rel="canonical"> so search engines know which URL variant to index.
