Great question and the answer is yes. Here is an excerpt from the Endpoint Encryption Manager Administration Guide - "Because Endpoint Encryption webHelpdesk Server uses HTTPS. You will need to provide it with a suitable SSL certificate. You can purchase one of these from Endpoint Encryption, or from other certificate vendors." Webrecovery is part of the webHelpdesk server that you install the SSL cert on during the original setup process. Hope this helps.

I should also add, what catches a lot of people out is they go to Verisign etc and ask for a cert, and verisign tries to sell them a Certificate SIGNING service. For the SSL server you need to supply a whole certificate, so your PKI of choice needs to generate a correctly named (the right URL of the server) Server Authentication certificate, not just sign one for you (because you don't yet have one!).
Our server does not create CSR's - you need to get your PKI to create that for you, or do it with IIS Cert Server or OpenSSL for example.
