Cloud-delivered protection for Windows Defender Antivirus, also referred to as Microsoft Advanced Protection Service (MAPS), provides you with strong, fast protection in addition to our standard real-time protection.

Note

The Windows Defender Antivirus cloud service is a mechanism for delivering updated protection to your network and endpoints. Although it is called a cloud service, it is not simply protection for files stored in the cloud, rather it uses distributed resources and machine learning to deliver protection to your endpoints at a rate that is far faster than traditional signature updates.

Enabling cloud-delivered protection helps detect and block new malware - even if the malware has never been seen before - without needing to wait for a traditionally delivered definition update to block it. Definition updates can take hours to prepare and deliver, while our cloud service can deliver updated protection in seconds.

The following video describes how it works:

Cloud-delivered protection is enabled by default, however you may need to re-enable it if it has been disabled as part of previous organizational policies.

Tip

You can also visit the Windows Defender Testground website at demo.wd.microsoft.com to confirm the feature is working and see how it works.
