We are a Product organisation and manage our development in Jira.
While all of our projects are private and visible only internally, I'd want to surface all the bugs related to my client on a shared Confluence page (eg Jira report filtering across all Projects by a ticket label).
Client doesn't need to go in the ticket itself, just see Jira report - Ticket # / Summary / Created / Status on Confluence page.
But because the projects are private client can't see a report.
Our projects are organised by a software component, not by a client, which means we can't share the entire project with a customer to provide the visibility.
The great thing about Jira report - all the ticket status update get automatically reflected, while any manual tracker gets out of date really quickly.
