Top issues to fix
6 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.
Meta description longer than 160 characters
SEOTrim the meta description to under 160 characters to avoid truncation in search results.
Missing OpenGraph tags
SEOAdd og:title/og:description/og:image so shared links render a proper preview card.
