Change Healthcare is the worst company I've worked for when dealing with IT and security. Lots of security theater getting in the way of the developer's machine because IT is scared of what can happen in dev and staging, whereas competent companies firewall development environments properly so it shouldn't be an issue getting root on your machine. IT monitors every single application that gets installed and scrutinizes you when it's obviously needed to do software work. Just a major pain in the ass. Inability to get root access to the machine. Overly dependent on username/password pairs to communicate between back-ends. Barely any integration testing. Mandatory drug tests.
Can't say I'm surprised that despite all this security theater, Change Healthcare still fails in many spectactular ways.
