Masking url on a Rise course

We are trying to post a Rise course on an internal site at our company using the Web export option.  The only issue is, when we upload our zip file to place on our internal site, the direct link to the course is visible by the user.  In theory, the user can then take that direct link and potentially forward it outside of the company.

We are aware that we can export to LMS but that avenue provides a few different steps for the user to access the course, which we're trying to avoid.  Are there any options for Rise courses or from Articulate in general to "mask" a url for publishing purposes?
