Top issues to fix
12 issues found · 3 high priority
Missing Strict-Transport-Security header

Missing Content-Security-Policy header
SecurityAdd a CSP to control which sources can run scripts — the strongest single defense against XSS.
No H1 heading found
SEOAdd exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.
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.
