Choosing between bring your own device (BYOD) and managed devices is an important strategic business decision, which involves more than technology alone. In this blog, we explore what factors play a part in making this choice and how Microsoft Intune supports both approaches.
Jane, an employee at a tech company, uses her personal phone for work, saving documents from work to her iOS Files. When Jane leaves the company, she has the company's source code on her personal device.
Without the safeguards provided by Device/App Management solutions, such as ‘retire device’ capabilities or restrictions on file transfers, company data is irretrievable and potentially at the disposal of a competitor, where Jane has just started a new job.
A company distributes phones to employees without device management policies. An employee, Mark, uses his personal Apple ID on his device, inadvertently locking corporate assets to his personal account.
When a disgruntled Mark exits the company, he leaves behind a phone tied to his Apple ID. The company, needing to repurpose the device, cannot unlock the phone due to company policies set against sharing passwords. This predicament underlines the necessity of management policies which ensure corporate property remains within company control.
App protection policies coupled with conditional access preventing organisation data transfer to unmanaged Applications (such as an iOS File App).
