When I was working with Digicert a decade ago, it was expensive, but they also had knowledgable support and with a wildcard cert, they would issue all sorts of 'custom duplicates' by request that were super handy. No incompetent sales, but certainly you do need to make sure accounting will pay.
Unfortunately DigiCert has gone way downhill.
We pulled all of our business after they failed to renew a cert with 30d(!!!) notice and got themselves stuck in a loop of useless org re-validations.
They were completely unresponsive and wasted dozens of hours of our time trying to rectify the situation before we pulled the plug and switched everything to ACME. I still can’t believe we wasted so much time and money with them.
