# Getting Started With Microsoft 365 on Prowler

???+ note "Government Cloud Support"
    Government cloud accounts or tenants (Microsoft 365 Government) are currently unsupported, but we expect to add support for them in the near future.

## Prerequisites

Configure authentication for Microsoft 365 by following the [Microsoft 365 Authentication](authentication.md) guide. This includes:

- Creating a Service Principal Application
- Granting required Microsoft Graph API permissions
- Setting up PowerShell module permissions (for full security coverage)
- Assigning appropriate roles to users (if using user authentication)

## Prowler CLI

Use Prowler CLI to scan Microsoft 365 environments.

### PowerShell Requirements

PowerShell 7.4+ is required for comprehensive Microsoft 365 security coverage. Installation instructions are available in the [Authentication guide](authentication.md#supported-powershell-versions).

### Authentication Options

Select an authentication method from the [Microsoft 365 Authentication](authentication.md) guide:

- **Service Principal Application** (recommended): `--sp-env-auth`
- **Interactive Browser Authentication**: `--browser-auth`

### Basic Usage

After configuring authentication, run a basic scan:

```console
prowler m365 --sp-env-auth
```

For comprehensive scans including PowerShell checks:

```console
prowler m365 --sp-env-auth --init-modules
```
