  • • Add Strict-Transport-Security header with max-age of at least 1 year
  • • Strengthen CSP by removing 'unsafe-eval'
  • • Add X-Frame-Options: DENY or SAMEORIGIN to prevent clickjacking
  • • Add Referrer-Policy header (recommended: strict-origin-when-cross-origin)
  • • Consider adding Permissions-Policy to control browser features
