    I have a multisite network with some sites mapped to their own domains and others remaining as subdomains. Would I need an SSL certificate for each mapped site (ie subdomain.com = subdomain.mydomain.com). Or can I use a wild card certificate to cover all the subdomains whether mapped or not? If I cannnot must I certificate both subdomain.mydomain.com and subdomain.com. I read that I even needed a separate certifcate for http://www.domain.com and domain.com.

    Single domain certificates will cover one domain and no subdomains (e.g. mydomain.com NOT sub.mydomain.com)

    Wildcard domain certificates will cover one domain and all subdomains (e.g. mydomain.com AND sub.mydomain.com)

    Multi-Domain certificates will cover X number of unique domains and all first level subdomains (e.g. mydomain.com, blog.mydomain.com, and myotherdomain.com). The certificate will specify how many unique domains it covers. The certificate provider will allow you to purchase additional domains to be covered under that same certificate.

    You CAN use a wildcard certificate to cover all subdomains mapped that match your root domain. This will NOT cover domains that are not the root domain. You would need to add an additional single/wildcard certificate to cover a domain that is not your root domain if you go this route. If you would like one certificate to cover all websites hosted on your server regardless of the root domain you will need to purchase a multi-domain certificate.

    Nowadays, most SSL certificates support both www and non-www domains, you don’t need to obtain separate certificate for http://www.domain.com and domain.com

    Wildcard SSL certificate can secure a single root domain and it’s all subdomains. You just need to add asterisk just before a common name.

    For example –

    Request certificate for *.domain.com, it will secure all subdomains as below.

    • mail.domain.com
    • shop.domain.com
    • anything.domain.com

    As per your requirements, you should choose multi domain wildcard SSL certificate. It can secure your multiple websites as well its unlimited subdomains.

    For example –

    • *.domain1.com
    • anything.domain1.com
    • *.domain2.co.uk
    • anything.domain2.co.uk
    • *.domain3.com
    • anything.domain3.com
