Microsoft IT enables employees to bring their own devices to work. IT distributes personal hardware budgets to internal departments. We have worked hard to make IT-standard devices be compelling and easy to acquire, but teams can buy what they want. We have clear practices related to support based on the device.
We expanded our device support with the growth of tablets and smart phones. We believe internal users should opt into being managed by IT, where they give up some control in order to get more access to corporate resources. For example, if the device doesn't have TPM-enforced bit locker and multi-factor authentication, the user can't get to sensitive data. We recommend Windows-based devices over others due to usability and security, and we provide guidance to employees with personal devices. That said, we have more than 10,000 iOS and Android devices on our network, and many more Macs (Microsoft has software for the Macintosh and a dedicated business group).
