It is scalable. Many people can be deployed on it. It has been used ever since I've been here.

It is providing security for all mainframe environments. We have 2,000 employees. For authenticating to the applications on the mainframe, everyone has to go through ACF2. When people leave the company, we have to delete the users. When people come in or change roles, they go through ACF2. This is our main security manager.

There is no issue with scalability. Its seems that a legacy product like this could have boundaries, but it could easily be extended securely using LDAP or AD groups.

The product is scalable. The largest mainframe shops can use it.

We have not had any issues with scalability.
