CAA Records (Certificate Authority Authorization)

CAA Records
Configured (Restricts certificate issuance)
Current Issuer

Authorized CAs
comodoca.com digicert.com ; cansignhttpexchanges=yes letsencrypt.org pki.goog ; cansignhttpexchanges=yes ssl.com
Wildcard CAs
comodoca.com digicert.com ; cansignhttpexchanges=yes letsencrypt.org pki.goog ; cansignhttpexchanges=yes ssl.com
Recommendations

  • • You have authorized 5 CAs - consider limiting to only the CAs you actively use
  • • Consider adding 'iodef' records to receive notifications about unauthorized certificate issuance attempts
