Does this mean that DigiCert is the only alternative?
I assume not, but we’d already used them for other things, and they didn’t have a problem doing it, so we didn’t shop any further.
And do they really have this offer for ordinary users, or is this also some special arrangement for big players only?
No, we didn’t have to do anything special, to the best of my knowledge.
That does make me wonder how they verify that I'm the rightful owner of "sites, IP addresses, common names, etc.". In particular, "etc" :-) Or you could ask yourself if you trust a CA with such an offer...
Yep. DANE is the correct answer. CAs are not. But that’s been true for a very long time, and people are still trying to pretend that CAs know what’s what. -Bill
