Given the sensitive nature of the content of some tickets, and the fact that you're asking users to register and login for the forum, I believe that the Maropost Marketing Cloud Support platform should be running over SSL with a valid certificate.
Please can you consider this request?
Instructions on how to add SSL support for FreshDesk can be found at https://support.freshdesk.com/support/solutions/articles/90479-configuring-a-custom-ssl-certificate-for-your-support-portal
Thanks for your inquiry.
We are actually considering alternatives to FreshDesk. I'll check internally as to the latest plans and timeline.
