# Azure Resource Group Scope

Prowler supports narrowing security scans to specific resource groups within Azure subscriptions. This is useful when you want to audit only a subset of resources rather than scanning an entire subscription.

By default, Prowler scans all resource groups it has permission to access. Passing `--azure-resource-group` limits the scan to only the specified resource groups across all accessible subscriptions.

## Configuring Resource Group Scoped Scans

To restrict a scan to one or more resource groups, pass them as arguments using the `--azure-resource-group` flag:

```console theme={null}
prowler azure --az-cli-auth --azure-resource-group <resource-group-1> <resource-group-2> ... <resource-group-N>
```

For example, to scan only `rg-production` and `rg-staging`:

```console theme={null}
prowler azure --az-cli-auth --azure-resource-group rg-prod1 rg-prod2
```

This works with all supported authentication methods:

```console theme={null}
# Service Principal
prowler azure --sp-env-auth --azure-resource-group rg-production

# Browser
prowler azure --browser-auth --tenant-id <tenant-id> --azure-resource-group rg-production

# Managed Identity
prowler azure --managed-identity-auth --azure-resource-group rg-production
```

## How It Works

When `--azure-resource-group` is provided, Prowler validates each specified resource group against all accessible subscriptions. A resource group is included in the scan if it exists in **at least one** subscription.

* If a resource group is found in one or more subscriptions, it will be scanned in those subscriptions only.
* If a resource group is **not found in any** subscription, Prowler logs a warning and skips it.
* If **none** of the provided resource groups are found across any subscription, Prowler logs a warning and no resource group scoped checks will run.
* Resource group names are matched case-insensitively, so `MyGroup` and `mygroup` are treated as the same group, mirroring Azure's own behavior.

<Warning>
  If `--azure-resource-group` is used, checks that apply to specific resources are limited to the relevant resource groups. But if checks that apply to tenant or subscription scope (identity, policy, or subscription-level configuration checks) are involved, then these checks will run in their natural scope.
