This is a bit of an open ended question and points to the best answer.
We have a windows file server that is virtualised and sits on a storage array. My question is, is it best practice to encrypt these files to protect the data that they contain. The files are of a client confidential nature but they are by no means strictly sensitive data.
Access to all files on this server is audited daily via a 3rd party monitoring tool but should I encrypt too?
