+## Custom Policies
+
+NGINXaas for Azure also supports custom security policies. You can create and modify custom security policies to deploy to NGINX App Protect Instances using the API or Azure Portal.
+
+### Manage Custom Policies
+
+To create a custom security policy in the Azure Portal:
+
+1. Select your deployment
+2. Select **NGINX app protect WAF** from the menu on the left
+3. Select **Custom Policies**
+4. Select **Add Custom Security Policy** to open the policy editor
+
+In the policy editor, enter the **Name**, **File path**, your policy content, and then select **Save**. The **File path** is optional and will default to the policy **Name** with a ".json" extension if not specified. The **Name** must have a ".json" extension.
+
+   {{< img src="nginxaas-azure/custom-policy-editor.png" alt="NGINXaaS Custom Policy Editor." >}}
+
+After your policy has been saved, you can then reference it in your NGINX configuration the same as you did for precompiled policies. For more information on policy configuration and syntax, refer to the NGINX App Protect [configuration guide](https://docs.nginx.com/nginx-app-protect-waf/v5/configuration-guide/configuration/).
+
+{{<note>}}The **name** field within the security policy must be unique among the policies referenced in your NGINX configuration.{{</note>}}
+{{<note>}}Referencing both custom and precompiled policies in your NGINX configuration is not supported at this time. See the [Known issues]({{< ref "/nginxaas-azure/known-issues.md" >}}) for a workaround for this limitation.{{</note>}}
+
+The **Custom Policies** tab shows the status of your custom policies (Compilation and Application Status). Custom Policies are automatically compiled when created or modified. Policies that are applied to the NGINX configuration cannot be deleted until they are first removed from the configuration.

+When using NGINX App Protect WAF, you can only reference default or custom security policies in your NGINX configuration, not both.
