Recommendations
  • • Consider using critical flag (flags=128) for stricter CAA enforcement
  • • You have authorized 9 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
