As we allow our staff to take issued mobile devices and files in and out of the office, we need to implement additional security to prevent misuse of units and loss of data. We want to keep track of the incoming and outgoing calls and use of applications and contents. We may not be able to have full control but at least could help us avoid abuse of usage that could also lead to additional expenses. We've heard about the Telecom and Data Control system and we'd like to get your thoughts on this? Would this be very helpful or it's just another expenditure?
