Top issues to fix
7 issues found · 3 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.
Slow estimated load (9.1s)
PerformanceUse a CDN, enable caching/compression, and cut render-blocking assets — every extra second costs conversions.
2 cookies without Secure/HttpOnly flags
SecuritySet Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.
Title longer than 60 characters
SEOShorten the title to under 60 characters so search results don't truncate it.
Meta description longer than 160 characters
SEOTrim the meta description to under 160 characters to avoid truncation in search results.
