Sure there are LOTS of vendors out there who claim their apps are all thats needed to be compliant, very few actually meet the requirements.
As I’ve already said though, browser based apps can be compliant if you lock the device down otherwise. But then you eliminate all the capabilities of the ipad.
So, the iOS encryption libraries available to any iPad app aren't good enough? Darn, I could have sworn I saw those on the NIST AES validation list a while back (which is necessary for FIPS 140-2, which is necessary for HIPAA).
