We use it a lot for federation, authenticating in-house or on premises, and that gives us access to an outside SaaS provider.
Also, we like the reverse proxy tool so much that in some instances we’re using SSO just for that and not even single sign-on.
Improvements to My Organization
It's really increased the security of our applications, and in some cases, has provided much more security. It does this even while some applications don't require multiple usernames and passwords.
Room for Improvement
The documentation is not good enough, particularly the installation documentation could be improved. Some things are left open to interpretation and others are simply not documented at all. CA will take liberties and make assumptions that your system is a certain way, and so the documentation is based on that.
It’s very stable, but we found some bugs and got workarounds quickly. We stress out SSO, from what I understand CA's reasoning is, but they're quick to resolve the issues.
We've had no issues at all with scalability, as it covers everything we do even at thousands of logins per minute.
Customer Service and Technical Support
We use them a lot and they're quick to pick up cases. We have almost a dedicated team with them that escalates up issues.
It’s fairly complex as it has lots of pieces. We’re in the process of upgrading and we’re building a mirrored environment and then moving everything over to it.
CA is great to work with, but to use it, just learn the product suites and how they interact. Make sure you have a good layout and make sure you have everything you need.
