The SIG Platinum for Enterprises gets $2.45/user/month for up to 99 users if paid monthly. There’s a slight discount if you spend for the whole year, and the prices per user will also get down as the number of users goes up.

Final Verdict

There’s little data about Comodo’s public DNS service, and it isn’t benchmarked by DNSperf.com either. However, the service is tested by the DNS Performance Test script, which queries several of the popular public DNS services from the location. SIG Gold suggests that it doesn’t encrypt DNS traffic, though it allows attractive web filtering possibilities. That said, it’s viable only if you can hit within its threshold of 300,000 DNS inquiries. On the other hand, SIG Platinum employs encryption and is meant for enterprise users, and is reasonably priced if you don’t accept any additional gateway output to control Internet access.
