Manage investigation cases

[Herr Püssel]

I'm looking for a tool to manage investigation cases in a small team, like:

• collecting/storing information for each case
• allocate/follow up tasks 
• using a workflow to follow a predefined investigation process
• preparing a report with key information about the investigation which can be shared to the management team
• restrict access to specific investigations to a few team members

Would Jira Work Management be a good tool for this or are there other Atlassian apps which are better suited?

Thanks!
