Does Comodo charge business to use SecureDNS?

Hi All,
wondering if anyone knows if Comodo charge companies/businesses to use the SecureDNS servers and if so any ideas how much?

I’d like to suggest to my company that they configure the internal DNS servers to use the Comodo SecureDNS servers as the forwarders instead of the ISP’s however I know the first response will be “how much is that going to cost us?”

Thanks in advance
