Way to anonymize people in group

For the community piece of a membership, is it possible to anonymize people? I run a cybersecurity companion membership. I have said no community because I don’t want people to accidentally share their cybersecurity weak spots in a group (as a cybercriminal that’s the first place I’d look for opportunities.) However, I also think it could be a good place for women small business owners to learn about cybersecurity together. Is there a way people could interact without exposing actual names/businesses? (Kinda the way kids’ platforms work where they have avatars and generated user names. In fact, this could give you a safe way for people to host kid memberships.) Possible?
