Multi Domain SSL Certs re HTTPS migration

[Dan-Lawrence]

Hi

How important is it that when migrating sites to HTTPS they have their own SSL certificates as opposed to choosing the much cheaper multi domain certificate options such as: https://www.namecheap.com/security/ssl-certificates/comodo/ev-multi-domain.aspx

I have been told really should have 1 certificate per domain and people generally unsure about multi domain certsificates ?

All Best

There's no difference, really. Multi-domain certificates have been around for years (UCC, which is what this basically is, isn't new at all) and I've never heard of any problems with them. If anything, a multi-domain EV like this better in the long run because EV is much harder to obtain (you have to be a corporation to get one). I wasn't aware that anyone was allowed to issue what is basically a EV UCC certificate but I guess it was inevitable (I am surprised they don't have EV wildcard yet)

For Google's purposes they want a valid, signed certificate. They don't care if it's a single domain or a multi-domain EV like this. All certificates are issued and validated the same way.
