mobile device management (MDM)

•  Microsoft Intune is an MDM and MAM provider for your devices

Microsoft Intune is a cloud-based service that focuses on mobile device management (MDM) and mobile application management (MAM). 

You control how your organization’s devices are used, including mobile phones, tablets, and laptops. You can also configure specific policies to control applications. For example, you can prevent emails from being sent to people outside your organization. Intune also allows people in your organization to use their personal devices for school or work. On personal devices, Intune helps make sure your organization data stays protected, and can isolate organization data from personal data.

Intune integrates with Azure Active Directory (Azure AD) to control who has access, and what they can access. It also integrates with Azure Information Protection for data protection. It can be used with the Microsoft 365 suite of products. For example, you can deploy Microsoft Teams, OneNote, and other Microsoft 365 apps to devices. This feature enables people in your organization to be productive on all of their devices, while keeping your organization’s information protected with policies you create.

In Intune, you manage devices using an approach that's right for you. For organization-owned devices, you may want full control on the devices, including settings, features, and security. In this approach, devices and users of these devices "enroll" in Intune. Once enrolled, they receive your rules and settings through policies configured in Intune. For example, you can set password and PIN requirements, create a VPN connection, set up threat protection

For personal devices, or bring-your-own devices (BYOD), users may not want their organization administrators to have full control. In this approach, give users options. For example, users enroll their devices if they want full access to your organization resources. Or, if these users only want access to email or Microsoft Teams, then use app protection policies that require multi-factor authentication (MFA) to use these apps.
