Allowing employees to use personal phones or computers can be convenient. They already know the device, and they can check email or join a meeting without carrying another piece of equipment.
But the business still needs to decide what work is allowed, which applications employees may use, and what happens to company information if a device is lost or an employee leaves.
Personal devices can be suitable for limited work when they meet your security requirements. Company-owned devices are a better choice for sensitive work, administration, or jobs that require large amounts of business data to be stored on the device.
What counts as a personal device used for work?
Bring your own device, often shortened to BYOD, includes reading company email on a personal phone, opening documents in mobile apps, or using a home computer to connect to a business system. Files may remain in the Downloads folder, and accounts can stay signed in after the work is finished.
Decide what employees may do
Set the rules according to the work and the information involved. You might allow employees to read email through an approved mobile app but require a company computer for customer database exports, payroll, system administration, or access to sensitive client records.
Staff should know which devices and applications are permitted, whether they may download files, and what they must do before selling or replacing the device.
Set minimum security requirements
A personal device should run an operating system that still receives security updates. It should have a screen lock, device encryption where available, current updates, and multifactor authentication on company accounts. A lost or stolen device must be reported quickly.
Keep business information inside approved applications or a managed work profile where possible. Device and app management tools can apply security settings and, on supported platforms, remove company data from managed apps. Tell employees what the business can see or remove before they enroll their device.
Plan for a lost device or departing employee
If a personal device is lost, IT may need to revoke active sessions, reset affected passwords, and remove company information from managed apps.
When an employee leaves, disable their account and active sessions at the agreed time. Remove company data from managed apps, check for downloaded files, and confirm that business information has been returned or deleted.
When to provide a company device
Use a company-owned device when an employee handles sensitive information, needs administrator access, stores a large amount of data locally, or requires specialist software. It is also the better choice when IT needs full control over updates, backups, applications, and security monitoring.
BYOD can work, but only when the rules are clear and the device can meet them. If your business allows personal devices, ask your IT provider to review the policy, access settings, and offboarding process before a lost phone or employee departure puts company data at risk.
