Question about SSH/SSL section in the documentation

Hello, we're in the process of setting up our own Satis repository and wondered if we could get some clarification on the Security section of the documentation.

The documentation says...

> To secure your private repository you can host it over SSH or SSL using a client certificate. In your project you can use the options parameter to specify the connection options for the server.

But the domain would already have an SSL certificate so would it not already be hosted over SSL?

Thank you
