BYO or Bring Your Own devices has become a controversial issue for companies as it allows employees to use personal devices for work purposes. While BYO can potentially save companies money and increase employee productivity, it also brings significant security risks if not implemented properly. These risks include exposed corporate data, loss of device control, and compatibility issues. Ultimately, how well or poorly BYO works depends on establishing clear policies, deploying mobile device management solutions, and ensuring users receive proper training and understand security requirements when using personal devices for work.
