Recommendations
  • • Increase HSTS max-age to at least 1 year and add includeSubDomains
  • • Strengthen CSP by removing 'unsafe-eval'
  • • Add X-Frame-Options: DENY or SAMEORIGIN to prevent clickjacking
  • • Add X-Content-Type-Options: nosniff
  • • Add Referrer-Policy header (recommended: strict-origin-when-cross-origin)
  • • Consider adding Permissions-Policy to control browser features
