Top issues to fix

9 issues found · 1 high priority

    Add HSTS so browsers always use HTTPS — this closes the protocol-downgrade attack window.

    Security

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

  • 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.

  • Title longer than 60 characters

    Shorten the title to under 60 characters so search results don't truncate it.

  • Meta description longer than 160 characters
