How to Protect Sensitive Data in Large Jira/Confluence Instances

Hi @Utkarsh Chandel while reviews have their place, i see that is a post fact check. I would prefere gating access as the first steps. 

User permissions in both jira and confluence, especially around delete, should be checked and made up to a standard. i woulld set delete permissions with only several users in the organization to constrain that with a bottle neck.

You cant guard against personal pages that user create in their blogs from being deleted, but as a practice, important documents should not be personal documents.

Another option is using a backup, in case something was lost unintentionally.  there are several options to consider here, from 3rd party apps, atlassian's own backup/restore solution, and doing manual backsups to a sandbox from which you can restore data.

I think a mix of both works well. High-risk projects and spaces should be monitored more frequently, while lower-risk areas can be checked on a regular schedule. That helps catch sensitive data early without putting too much load on larger Jira and Confluence instances.

It also makes sense to adjust the scan frequency based on the type of data and how often that area changes.
