Recommendations
  • • Add Strict-Transport-Security header with max-age of at least 1 year
  • • Improve CSP by adding more specific directives and removing 'unsafe-inline'
  • • Add X-Frame-Options: DENY or SAMEORIGIN to prevent clickjacking
  • • Consider adding Permissions-Policy to control browser features
