Recommendations
  • Increase HSTS max-age to at least 1 year and add includeSubDomains
  • Improve CSP by adding more specific directives and removing 'unsafe-inline'
  • 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
