Are you interested in purchasing SharePoint SSL? This article explains the actions you will need to take.

We support assigning a dedicated SSL certificate to your SharePoint site. 

There is a monthly fee associated with this and will be determined by our sales department. It your responsibility to provide us with the SSL certificate in the PFX format. We do require the password to the PFX file. 

If you would like us to provide the CSR, then we can do so. This would be used when you purchase the certificate. 

If you have us provide the CSR, you will then use that CSR with the certificate authority to order a certificate and you will also have to provide us with the response from the certificate authority and we'd generate the PFX and assign the certificate. 

Please Note: We only support certificates purchased from Thawte.
