Top issues to fix

10 issues found · 2 high priority

TLS certificate expires in 13 days
Security
Renew now (or enable auto-renewal) — an expired certificate blocks visitors with a full-page browser warning.
Missing Strict-Transport-Security header
Security
Add HSTS so browsers always use HTTPS — this closes the protocol-downgrade attack window.
Missing X-Content-Type-Options header
Security
Add X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.
Missing X-Frame-Options header
Security
Add X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.
Title longer than 60 characters
SEO
Shorten the title to under 60 characters so search results don't truncate it.
Meta description longer than 160 characters
SEO
Trim the meta description to under 160 characters to avoid truncation in search results.
