How to differentiate access rights in Confluence for two companies with different access conditions?

Question

Active Directory

We need to organize the use of Confluence by two companies.
All employees of these companies connect to Confluence through AD.
For simplicity, let's introduce the following concepts:
Company 1 - employees must see all spaces and sections
Company 2 - only certain employees must see certain sections of one space
Company 2 connects via VPN. If you open access to Confluence through this connection, then all anonymous users of company 2 will see all spaces and sections, similar to employees of company 1.
How can I restrict anonymous access to employees of company 2? At the same time, employees of company 1 should not lose anonymous access.
Perhaps someone has already encountered such a problem, help in solving it, please.

Answer 1

Well, as an option for each space, make your own group of users, limit viewing and editing for this group. Add new employees to this group.
As a rule, the delimitation of roles in Confluence is poor, viewing is for everyone, but inside the space it is individual.
