The (internal) API takes the inputs, runs some stored procs (internalen-USTelligent Community 12https://community.appian.com/thread/65006?ContentTypeID=1Tue, 05 Mar 2019 05:32:59 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:6ac44a04-3d52-4eb0-bfa0-208aadf09d4cStefan HelzleHi Dylan, we built an application for management of medical practices including sensitive medical data.

To separate sensitive data we implemented a hashed keying method so there is no direct shared key between the tables.<br /> <br /> So restricting access in Appian is pretty simple. The question is, do you really need to encrypt data on DB level?<div style="clear:both;"></div>
