## Allow connections to the Windows Defender Antivirus cloud service
The Windows Defender Antivirus cloud service provides fast, strong protection for your endpoints. Enabling the cloud-delivered protection service is optional, however it is highly recommended because it provides very important protection against malware on your endpoints and across your network.

>The Windows Defender Antivirus cloud service is a mechanism for delivering updated protection to your network and endpoints.

After you've enabled the service, you may need to configure your network or firewall to allow connections between it and your endpoints.
As a cloud service, it is required that computers have access to the internet and that the ATP machine learning services are reachable. The URL: "\*.blob.core.windows.net" should not be excluded from any kind of network inspection. The table below lists the services and their associated URLs. You should ensure there are no firewall or network filtering rules denying access to these URLs, or you may need to create an allow rule specifically for them (excluding the URL: "\*.blob.core.windows.net"). Below mention URLs are using port 443 for communication.
