BYOD (Bring Your Own Device) is a workplace policy that allows employees, contractors, or guests to use their personal devices - such as smartphones, tablets, or laptops - for work-related tasks and to access company networks or data. While BYOD offers flexibility, convenience, and potential cost savings for organizations, it also introduces security risks, such as data breaches or unauthorized access, if not properly managed. Effective BYOD programs typically include security protocols, device management solutions, and clear guidelines to protect sensitive information.
