Missing Strict-Transport-Security header
Security
Add HSTS so browsers always use HTTPS — this closes the protocol-downgrade attack window.
Slow estimated load (5.4s)
Performance
Use a CDN, enable caching/compression, and cut render-blocking assets — every extra second costs conversions.
1 cookie without Secure/HttpOnly flags
Security
Set Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.
