Top issues to fix
7 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.
Missing OpenGraph tags
SEOAdd og:title/og:description/og:image so shared links render a proper preview card.
Missing html lang attribute
AccessibilitySet <html lang="…"> so screen readers pick the right pronunciation rules.
