Top issues to fix

5 issues found · 1 high priority

  • Missing Content-Security-Policy header

    Security

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

  • 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.

  • Meta description longer than 160 characters

    SEO

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

  • 1 broken link on the page

    SEO
