 #  What is Azure Virtual Network encryption?
 
-Azure Virtual Network encryption is a feature of Azure Virtual Networks. Virtual network encryption allows you to seamlessly encrypt and decrypt traffic between Azure Virtual Machines. 
+Azure Virtual Network encryption is a feature of Azure Virtual Networks. Virtual network encryption allows you to seamlessly encrypt and decrypt traffic between Azure Virtual Machines by creating a DTLS tunnel. 
 
-Whenever Azure customer traffic moves between datacenters, Microsoft applies a data-link layer encryption method using the IEEE 802.1AE MAC Security Standards (MACsec). This encryption is implemented to secure the traffic outside physical boundaries not controlled by Microsoft or on behalf of Microsoft. This method is applied from point-to-point across the underlying network hardware. Virtual network encryption enables you to encrypt traffic between Virtual Machines and Virtual Machines Scale Sets within the same virtual network. It also encrypts traffic between regionally and globally peered virtual networks. Virtual network encryption enhances existing encryption in transit capabilities in Azure.
