Collaborating With

Organizations that invited you to view their account, from Settings → Users.

Collaborating With

Collaborating With appears on Settings → Users only when you are viewing your own account and at least one other organization has invited you.

Card copy: These organizations have invited you to view their account details. You are currently viewing OPEN vulnerabilities.

It does not list people you invited (that is Authorized Users). It lists tenants that granted you collaborator access.

Switch into a collaborator tenant from the account menu (organization name/logo, or email if no profile is set). The card is hidden while impersonating.
