@Priya Kothandapani Thanks for reaching out.

Both Azure Private Endpoint and Azure App Service Environment (ASE) provide secure network access to your Azure App Service or Function App. However, they serve different purposes and can be used together to provide an even more secure environment.

Azure Private Endpoint is a network interface that connects you privately and securely to a service powered by Azure Private Link. Private Endpoint uses a private IP address from your virtual network, effectively bringing the service into your virtual network. You can use Private Endpoint for your functions hosted in the Premium and App Service plans. If you want to make calls to Private Endpoints, then you must make sure that your DNS lookups resolve to the private endpoint.

On the other hand, Azure App Service Environment (ASE) is a fully isolated and dedicated environment for securely running Azure App Service apps at high scale. ASE is ideal for application workloads requiring very high scale and isolation and secure network access. ASE is always deployed into a virtual network, and customers have fine-grained control over both inbound and outbound application network traffic.

You can use either ASE or Private Endpoints, or both together, depending on your specific security requirements. ASE provides a fully isolated environment for running your apps, while Private Endpoints provide secure access to your apps over a private endpoint.

If you require additional security and isolation for your apps, you can use both ASE and Private Endpoints together. This will provide the highest level of security and isolation for your apps.
