 ## Traffic interception technologies
 
-Some enterprise customers use traffic interception, SSL decryption, deep packet inspection, and other similar technologies for security teams to monitor network traffic. Cloud PC provisioning may need direct access to the virtual machine. These traffic interception technologies can causes issues with running on-premises network connection checks or Cloud PC provisioning. Make sure no network interception is enforced for Cloud PCs provisioned within the Windows 365 service.

+## Bandwidth
+
+Windows 365 uses the Azure network infrastructure. An Azure subscription is required when a virtual network is selected while deploying Windows 365 Enterprise. Bandwidth charges for Cloud PC usage include:
+
+- Network traffic into a Cloud PC is free.
+- Outbound (egress) traffic incurs charges against the Azure subscription for the virtual network.
+- Office data (like email and OneDrive for Business file sync) incurs egress charges if the Cloud PC and a user’s data reside in different regions.
+- RDP networking traffic always incurs egress charges.
+
+For more information about costs associated with data transfers, see [Bandwidth pricing]( https://azure.microsoft.com/pricing/details/bandwidth/).
