CAA records are a new type of DNS record that allows you to restrict which Certificate Authorities can issue SSL certificates for your domains.
As ServerPilot's AutoSSL feature issues certificates through the Let's Encrypt Certificate Authority, you can optionally choose to create an issue CAA record with authority granted to letsencrypt.org so that only Let's Encrypt will be able to issue SSL certificates for your domain.
