Sorry for my bad English.
I've been looking for a solution to encrypt files on the company's file server for a long time.Our intention is to be able to encrypt information not just to protect ourselves from an external attack or theft, but rather to protect ourselves from a user taking sensitive information from the company.
EFS I don't see it practical with a file server with a multitude of folders and groups for groups of users, in addition a user with permissions to those files could also take the information to an external computer.
This I understand that I will have to do with a DLP software and that Microsoft does not offer any solution (although I have read something from the Azure Informaticon Protection, but I see it too complicated and do not just convince me for the local file server).
I see that there are many solutions Mcafee, symantec, eset, sophos, Sealpath. But I have little experience in this type of software.
Any recommendations?
