Top issues to fix

14 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.

  • Missing viewport meta tag

    Accessibility

    Add <meta name="viewport" content="width=device-width, initial-scale=1"> — without it the site is broken on mobile.

  • TLS certificate expires in 24 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.

  • Missing X-Frame-Options header

    Security

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