Re: "learn to defend themselves against audits"
It's not really that simple. You buy a license to use some kind of enterprise software, there is a good chance that you agree to be audited to demonstrate your compliance with that license. If you don't agree to allow that, you aren't in compliance with the license and should stop using it. Fine if it's just me not liking the license clause for Office or something similar, a little harder when you are a large enterprise that depends on a particular piece of software and cannot quickly or easily replace it.
Sure they can't barge their way in, but they can send you a cease and desist letter telling you to either comply or stop using the software. And ultimately they have legal recourse then to get you to prove you have stopped using the software and have removed it from your business.
The bigger issue is that way that many large companies make the licensing deliberately vague so it's hard to know if you are using it in a compliant manner or not. I think that is what this new forum is trying to help with.
