Google’s mobile operating system contains a huge amount of threats, including malware, phishing apps, trojans, and more. Google removes hundreds or even thousands of applications every month. But, many of these dangerous apps end up in users’ devices.

Microsoft Defender ATP for Android should solve this problem. This application allows you to scan your phone for malware and detect phishing attempts. When Microsoft Defender ATP detects malware, it restricts access to critical applications such as email clients and online banking applications to prevent further damage. If there is a threat, Microsoft Defender ATP will warn you about it.

Microsoft Defender ATP is currently still in a preview phase for Microsoft 365 customers. For all others, the antivirus will become available in the coming months.

Blocking access to sensitive data

Additional layers of protection against malicious access to sensitive corporate information are offered by integrating with Microsoft Endpoint Manager. It includes both Microsoft Intune and Configuration Manager. For example, a compromised device would be blocked from accessing Outlook email. When Microsoft Defender ATP for Android finds that a device has malicious apps installed, it will classify the device as “high risk” and will flag it in the Microsoft Defender Security Center. Microsoft Intune uses the device’s risk level in conjunction with pre-defined compliance polices to activate Conditional Access rules that block access to corporate assets from the high-risk device.

 Unified SecOps experience

The Microsoft Defender Security Center acts as the single pane of glass experience for security teams to get a centralized view of threats and activities. All the alerts for phishing and malware on Android devices are surfaced here. As part of the alert, analysts see the name of the threat, its severity, the alert process tree for the incident, and other additional context including file details and associated SHA information. Android device-related alerts also roll up into the incident where analysts can get a more holistic view of attacks associated with a device.
