Top issues to fix

7 issues found · 4 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.
No H1 heading found
SEO
Add exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.
Missing viewport meta tag
Accessibility
Add <meta name="viewport" content="width=device-width, initial-scale=1"> — without it the site is broken on mobile.
Missing X-Frame-Options header
Security
Add X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.
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.
