Sharing design data for viewing purposes on premise to external public parties?

Is there a workflow for sharing design data to interested general public like potential buyers of some machine equipment etc...? Since is On Premise one can't just invite people to their platform through VPN... It needs to be continuous way. As design progresses user should not make copies or export-import somewhere since is potential for errors but needs to be able to update potential buyer...

Sharing via 3D drive to external people is not an option at the time since there is no control on the link rights (Can View / Can Edit) it provides download button and that's not safe since only viewing purposes are required.
