During the past few years the use of mobile devices became extremely popular not only for personal use but also for working. When personal mobile devices are used as working assets the enterprises should search for some suitable ways to protect their data and network from the unmanaged mobile devices. On the other hand, it is widely believed that employees are more productive when they work from their own devices. This arise three questions: what risks these devices are bringing to the organizations, how to protect the company data and network while allowing the employees to work from their devices, and how adapted the real world is to the Bring Your Own Device trend. To answer these questions and the sub-questions deriving from them, an extensive literature study and a survey approach are used. The results from the study show that even though there are many risks for the companies, brought by the use of personal mobile devices, there exist adequate solutions to mitigate these risks. However, the results from the survey approach show that the companies are not very adapted to this trend yet and there exist a need for better understanding of the problem.
