Top issues to fix
15 issues found · 5 high priority
TLS certificate expires in 2 days
SecurityRenew now (or enable auto-renewal) — an expired certificate blocks visitors with a full-page browser warning.
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 viewport meta tag
AccessibilityAdd <meta name="viewport" content="width=device-width, initial-scale=1"> — without it the site is broken on mobile.
Slow estimated load (5.0s)
PerformanceUse a CDN, enable caching/compression, and cut render-blocking assets — every extra second costs conversions.
Missing X-Content-Type-Options header
SecurityAdd X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.
