Now, audits are generally not worth very much (even, perhaps even especially, from a Big Four group like KPMG), but for this type of thing (verifying that a company isn't doing something they promised they would not do) they're about the best we have.
KPMG's risk department - the lawyers' lawyers - appears to be violently allergic to their customers disclosing any report to outside parties. Based on my experience you can get a copy, but first you and the primary customer need to submit some paperwork. And among the conditions you need to agree with is that you don't redistribute the report or its contents.
Disclosure: I deal with security audits and technical aspects of compliance.
Isn't that the entire point of such an audit? To be able to present it to outside third-parties?
For examples, Mozilla (CA/B) requires audits for root CAs. The CA must provide a link to the audit on the auditor's public web site -- forwarding a copy or hosting it on their own isn't sufficient.
If you've ever been audited for some other reason, you'll know they find lots of things, and then you fix them, and that's "fine". But well, is it fine? Or, should we acknowledge that they found lots of things and what those things were, even if you subsequently fixed them? The CA/B says you have several months to hand over your letter after the audit period. Guess what those months are spent doing...
