CAA Issues
- • CRITICAL: Current certificate issuer 'C=US, O=DigiCert Inc, OU=www.digicert.com, CN=Thawte TLS RSA CA G1' is NOT authorized by CAA records. Authorized CAs: amazon.com, comodoca.com, letsencrypt.org, thawte.com
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
