FileVault is an extra layer of login protection implemented on Jamf managed Mac computers. It does not impede everyday use of the computer. The main function of FileVault is to encrypt the startup volume of Mac computers. When a user profile is created on a Jamf managed Mac computer, FIleVault is enabled for them and a recovery key is logged on Jamf servers for IT to provide recovery assistance if needed.
If the setup of FIleVault is interrupted or does not complete, it will trigger an Encrytion Key Escrow pop-up that cannot be skipped. There is nothing wrong with your computer. This is a standard IT related pop-up. That interaction will look like the pictures below.
