Forcing anonymity on all participants

I am working in a space where confidentiality is vital.
I want to facilitate calls where all external participants are anonymous.
The onus must be on me to guarantee anonymity, not the other participants (asking them to change display name is not acceptable).
So ideally the other participants should be able to join a call in whichever manner makes them comfortable, and as host I force the anonymity.
Is this possible, and if so what can I do to achieve this? Thanks

Hi ,

If you use our Webinar product, you would have the ability to hide attendees from one another. Only the panelist(s)/host would be able to see the attendees. Would that be sufficient?
