Online security made easier for you and your family. The Microsoft Defender app helps protect your family from online threats across your devices. The Microsoft Defender app is available exclusively with a Microsoft 365 Personal or Family subscription.
On your PC, Microsoft Defender works with built-in Windows Security to provide additional device protection on your Android, iOS, and Mac devices. With the cross-device app, you can manage and monitor your individual and your family's online security statuses in an easy-to-use dashboard. Stay safer with real-time notifications, security tips, and expert guidance that give you easy-to-follow recommendations. To get started, download the app and log-in with your Microsoft account. You will need an active Microsoft 365 Personal or Family subscription to activate Defender on your devices.
The Microsoft Defender app is also available for your Android, iOS and Mac devices. In the app, you can send an invite to download Microsoft Defender on your other devices. You can also easily access your dashboard in a web browser when you're on-the-go.
