 ===== Service Endpoints ===== ===== Service Endpoints =====
-  * Service Endpoints allow you to restrict access to your PaaS resources to traffic coming from your Azure Virtual Network.+  * Service Endpoints allow you to restrict access to your PaaS resources to traffic coming from your Azure Virtual Network. By default many Azure services allow access from the Internet to the service's public endpoint/IP. In many cases this is not needed and it reduces the attack surface to only allow access from select customer networks.

 +  * The key difference between Private Link and Service Endpoints is that with Private Link you are injecting the multi-tenant PaaS resource into your virtual network. 
 +  * With Service Endpoints, traffic still leaves your Vnet and hits the public endpoint of the PaaS resource, with Private Link the PaaS resource sits within your Vnet and gets a private IP on your Vnet. When you send traffic to the PaaS resource, it does not leave the virtual network.
