BYOD in Business: How to Protect Your SME When Employees Use Personal Devices

BYOD (Bring Your Own Device) refers to the practice of employees using their personal smartphones, tablets, and computers for professional purposes. According to the Allianz Risk Barometer 2024, cyber incidents are the number one risk for businesses, and unregulated BYOD is a major vector.

For Swiss SMEs, the concrete consequences of an insufficient BYOD policy include: customer data leaks, violations of the nLPD (new Federal Data Protection Act, in force since September 2023), rebound cyberattacks, and business interruptions.

This practical guide explains how to effectively manage BYOD with five accessible measures: define a clear policy, protect devices, separate professional and personal data, control access, raise awareness among your teams, and plan for emergencies. Concrete advice, without technical jargon, to protect your business without overcomplicating things.
