Which companies don't have DNS CAA records?
CAA (Certificate Authority Authorization) DNS records specify which Certificate Authorities are permitted to issue certificates for a domain. Without CAA, any of the hundreds of public CAs can issue a certificate, increasing the risk of unauthorized or misissued certificates that could be used in man-in-the-middle attacks.
