I found FileAuditor useful for monitoring access to sensitive info within our organization. The automated classification of vulnerable data saves plenty of work for our IT department, and the access rights audit feature. Review collected by and hosted on G2.com.

I feel that about customizing them to be somewhat limited to my needs. The current ones look less sophisticated and if not well tuned, you might end up having alert fatigue. Review collected by and hosted on G2.com.
