I rate NetIQ Identity Governance's scalability an eight to nine out of ten. 

It is a scalable solution. 

I give the scalability a nine out of ten.

The solution is scalable.

There are no problems with scalability.

The largest implementation we made with this product was in a bank in Chile and they had more than 12,000 identities. It scaled very well. We were a little worried at first as we had never done something that big. However, it scaled perfectly. There was no problem. I don't know if it would hold up if we implemented it in a bigger customer, for example, someone with 100,000 identities. I don't know for sure how it would behave in this case. That said, I've never had an issue.

No issues encountered.

The solution is scalable.
