I have a web-site - for instance, https://website.com - and I need to provide an SSL certificate for this web-site and a couple subdomains - for instance, https://subdomain.website.com and https://my.website.com

In another situation, I would use wildcard SSL certificate, which works for subdomains, but I want an Extended Validation certificate with green address bar (example image). As far as I know, there are no wildcard EV certificates.

However, there are multiple-domain EV certificates. Can I use this one to provide security for my domain and its subdomains. Or are there any other more proper and\or cheaper options?


If you need your sub domains to have EV, then I'd go for the multiple domain ev.
