Bring Your Own Device (BYOD) policy, which allows employees to use their own mobile devices for work and connection to their corporate network, is getting popular in enterprises. While companies want to improve the efficiency and productivity of employees, employees prefer to use their own devices at work, which make them feel more comfortable and free. Although BYOD seems attractive, companies and employees have some security concerns in different and various ways. The aim of this study is to explore employee and organization perspectives about BYOD. Empirical part of the research has two parts: Qualitative and quantitative. Manager's opinions were determined through a series of interviews and then the findings were analyzed. In quantitative part, a questionnaire has been developed based on the literature review and qualitative findings. 12 interviews and 93 surveys were used in the analysis. It has been found that while organizations and employees percept BYOD as having benefits in many ways, their security and privacy concern is a strong barrier on the implementation of BYOD policy.
