We use it in our company for our mainframe. It is used for authenticating users and giving users access to profiles and various resources. So, it is for authentication and giving access to users, and it also does logging and things like that.

It is currently hosted in-house. We are using its latest version. We are always on current versions.

Our primary use is to be able to review log events through reporting.

To provide security for the z/OS operating system.

We use CA ACF to manage security, provision users, and deprovision users from mainframe applications.
