Azure Private Endpoint vs Service Endpoint

So you created a Storage Account, SQL Database, or Key Vault — and now you’re wondering…

Should I use a Service Endpoint or a Private Endpoint?

These two features are critical for securing Azure PaaS services. But they’re not the same.
Let’s break them down clearly with real-world context.

What is a Service Endpoint?

Service Endpoints extend your VNet’s private IP to Azure PaaS services.

What it does:

  • Allows you to access Azure services over Azure backbone
  • Still uses the public IP of the service
  • Improves security by restricting access to your VNet only

Example Use Case:

10.0.1.4 (VM in subnet) --> Storage Account
If Service Endpoint is enabled for "Microsoft.Storage", your subnet can talk to it — even though the storage has a public IP.

What is a Private Endpoint?

A Private Endpoint creates a private IP in your VNet that maps to an Azure resource.

What it does: Fully private IP communication (no public IP usage) Appears like the resource is inside your own VNet Uses Private Link behind the scenes

Example Use Case:

10.0.1.4 (VM) --> 10.0.1.5 (Private Endpoint IP for SQL)
Even DNS will resolve to a private IP. It’s like having your SQL Database or Key Vault inside your own network.

Comparison Table

Feature Service Endpoint Private Endpoint IP Type Public IP of service Private IP in your VNet Uses Azure Backbone Yes Yes Private DNS No Yes (with Private DNS zone) Security Scope Subnet Level NIC Level (granular) Access Model Extended access to Azure PaaS Private IP connectivity Supported Services Many (Storage, SQL, KeyVault) Many, growing list

When to Use What?

Scenario Recommended Choice Quick and simple access control Service Endpoint High security / no public exposure Private Endpoint Need full DNS privacy Private Endpoint You manage multiple services Private Endpoint

Real-World Tip

If you’re working in regulated industries (finance, healthcare, etc.), Private Endpoints are preferred to meet compliance needs (no public IP traffic).
