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
