Our jira instance is used for several different products and has corresponding service desks to support the 3 main products we support. The issue im running into as we expand is that one of the product teams wants to be able to open up their portal to be able to have any user logged in or not submit requests but those users should not be able to see the other projects. While it is fine for now as i can simply hide the projects that only logged in users can submit to if another product chooses to start doing something similar then i cannot "Hide them" from each-others users.
Overall i need a solution to have multiple external portals from our jira instance so that users cannot see the other ones. any suggestions would be helpful.
