Is this the solution for my business to create collaboration and ease of access of information?

I think this service may be the solution to my needs....if it works the way I'm understanding it.  Let me know if there is something else offered. Here is my scenario:  I have a chain of command with 4 people.  Person number 1, needs to meet with a client and ask questions and fill their response on the ipad via a form/digital pdf. From there they need it available to Person number 2 and 3 to review and comment in a collaborative space, along with add on to the form itself when the meet with this same client.  From here all this information is sent to person number 4 for review and additional comments. 

At this point tho, the information should still be available to anyway I deem needing to know this information on this client.  How much control do I have on who see's this clients information.  Does adobe protect this information as well from a HIPPA standpoint. Is this really how this adobe pdf service works?

Thank you in advance!
