Help to create separate space for particular project

[IT ADMIN]

Help to create separate space for particular project and they are not see another project of confluence.

[Andy Gladstone]

@IT ADMIN can you clarify what exactly you are looking for? Do you want users to only see specific spaces in Confluence, but not others, even while in the same instance? 

In order to remove access to users or groups for a specific space, you need to set their View permission to ❌.

Here is an excerpt from this page: https://support.atlassian.com/confluence-cloud/docs/assign-space-permissions/#What-the-individual-space-permissions-do

Hope this helps!

If the view permission is revoked for the user or group, they won't be able to view any content in the space. They won't be able to find the space or any of its content, neither in search results nor by browsing spaces on the site.
