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

CAA Records
Not Configured (Any CA can issue certificates)
CAA Issues
  • • No CAA records configured - any CA can issue certificates
Recommendations
  • • Implement CAA records to restrict which CAs can issue certificates for your domain
  • • This adds an extra layer of security against unauthorized certificate issuance
  • • Example: Add CAA record 'example.com. CAA 0 issue "letsencrypt.org"'
  • • Consider adding 'iodef' record to receive security incident reports
