The entire call (which we ended up pulling and listening to, and then sent back to COMODO as a prime example as to why we're threw with their business) was designed to have a non-technical decision maker make an impulse decision over the phone to buy thousands of dollars worth of certificates again.
Wildcard certs from Let's Encrypt cannot come soon enough.
We're on LE for 90%. There's a client (there always is...) that demands Network Solutions certs. Yet they cannot put to words why that's their need, other than stupid bullyish business practices.
We're still trying to wrap our heads how LE plans to offer wildcards.. But I digress.
Are you billing them for the extra cert, and for the extra work that using a non-standard CA implies?
It's a pain,but we have only 14 machines we oversee, with 3 year certs on each. Nagios takes care of alerts within 60 days, so we can easily get the request in time.
The real security hole was that the operators were patching through salesmen directly to the security staff without verifying who they were...
