How are you managing access reviews and access revocation across a large number of Jira projects?

[Utkarsh Chandel]

We manage 800+ Jira projects, and reviewing project access manually is becoming harder to keep up with.
I’d be interested to hear how other Jira admins are handling this:
Do you run regular access reviews for your Jira projects?
How do you identify users who no longer need access?
How do you revoke access when it comes through groups, project roles, or permission schemes?
Is your process mostly manual, automated, or a mix of both?
Would be useful to hear what’s actually working for you at scale.
