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 Referrer-Policy header (recommended: strict-origin-when-cross-origin)
  • • Consider adding Permissions-Policy to control browser features

Configured (Restricts certificate issuance)
Current Issuer

Recommendations
  • • Consider using critical flag (flags=128) for stricter CAA enforcement
  • • You have authorized 4 CAs - consider limiting to only the CAs you actively use
  • • Consider adding 'iodef' records to receive notifications about unauthorized certificate issuance attempts
  • • Consider adding 'issuewild' records to control wildcard certificate issuance
