CAA Issues
- • CRITICAL: Current certificate issuer 'C=FR, O=Gandi, CN=Gandi RSA Domain Validation Secure Server CA 3' is NOT authorized by CAA records. Authorized CAs: letsencrypt.org, globalsign.com, comodoca.com, pki.goog, digicert.com, amazon.com
Recommendations
- • Consider using critical flag (flags=128) for stricter CAA enforcement
- • You have authorized 6 CAs - consider limiting to only the CAs you actively use
- • Consider adding 'iodef' records to receive notifications about unauthorized certificate issuance attempts
