Top issues to fix

13 issues found · 5 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 title tag
SEO
Add a unique, descriptive <title> tag — it's the single most important on-page SEO element.
Missing meta description
SEO
Add a ~150-character meta description to control your search-result snippet and lift click-through rate.
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-Content-Type-Options header
Security
Add X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.
