Top issues to fix
13 issues found · 2 high priority
Missing Strict-Transport-Security header
SecurityAdd HSTS so browsers always use HTTPS — this closes the protocol-downgrade attack window.
Missing Content-Security-Policy header
SecurityAdd a CSP to control which sources can run scripts — the strongest single defense against XSS.
Missing X-Content-Type-Options header
SecurityAdd X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.
Missing X-Frame-Options header
SecurityAdd X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.
1 cookie without Secure/HttpOnly flags
SecuritySet Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.
Title longer than 60 characters
SEOShorten the title to under 60 characters so search results don't truncate it.
