App protection policies (APP) ensure a company's critical information is safe in certain apps. These rules can stop people from doing certain things with the data or keep an eye on what they do with it when they're in the app. An app is called "managed" if it has these rules, and Microsoft Intune can help manage them.
Mobile Application Management (MAM) app protection policies help you manage and protect your organization's data in certain apps. Many useful apps, like the Microsoft Office apps, can be managed this way with Intune MAM.
You can use Intune app protection policies to protect your company's important information, even if you're not managing the device it's on. You can keep your data safe without enrolling the device in Microsoft Intune for management. By setting up rules for certain apps, you can control who gets to see important company stuff and ensure it stays in the right hands.
