We are only audit the movement of office software files like excel, word, pdf and so on. The copy of files from computer to USB drives are too slow, is it normal? How can we improve performance?
It took two minutes and a half in copy 185MB from computer to USB disk, it needs some seconds without DLP software.
Look into disabling the "Advanced File Copy Protection" setting in the DLP Client Configuration 'Operational Mode and Modules'. There are some security drawbacks to disabling that setting (as defined in the Product Guide), but it should speed up performance.
