How much protection does Pointstone Total Privacy offer?

Hi! I'm a clerk working in a publishing office. All of the computers in our office are connected to a main server. We are not prohibited by our boss to use the computers for our personal use. But, still I'm very wary that the IT Department may track private conversations and open our personal files saved in these computers. Can Pointstone Total Privacy protect a computer belonging to a local area network from being traced and infiltrated illegally by its own mother server?
