-## Step 1: Get Microsoft Defender ATP
-
-To get started, you must have Microsoft Defender ATP with licenses assigned and provisioned per the following steps:
-
-1. Buy or try Microsoft Defender ATP today. [Visit Microsoft Defender ATP to start a free trial or request a quote](https://aka.ms/mdatp).
-
-2. Verify that your licenses are properly provisioned. See [Check license state](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/production-deployment#check-license-state).
-
-3. As a global administrator or security administrator, set up your dedicated cloud instance of Microsoft Defender ATP. See [Microsoft Defender ATP setup: Tenant configuration](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/production-deployment#tenant-configuration).
-
-4. If endpoints in your organization use a proxy to access the internet, see [Microsoft Defender ATP setup: Network configuration](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/production-deployment#network-configuration).
-
-## Step 2: Grant access to the Microsoft Defender Security Center
-
-The Microsoft Defender Security Center ([https://securitycenter.windows.com](https://securitycenter.windows.com)), also referred to as the Microsoft Defender ATP portal, is where you can access the features and capabilities of Microsoft Defender ATP. [Get an overview of the Microsoft Defender Security Center](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/use).
-
-Permissions to the Microsoft Defender Security Center can be granted by using either basic permissions or role-based access control (RBAC). We recommend using RBAC so that you have more granular control over permissions.
-
-1. Plan the roles and permissions for your security administrators and security operators. See [Role-based access control](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/prepare-deployment#role-based-access-control).
-
-2. Set up and configure RBAC. You can choose from one of several different methods. We recommend using [Intune](https://docs.microsoft.com/mem/intune/fundamentals/what-is-intune), especially if your organization is using Windows 10, macOS, iOS, and Android devices. See [setting up RBAC using Intune](https://docs.microsoft.com/mem/intune/fundamentals/role-based-access-control).
-
- Depending on your organization's needs, you can use a different method, such as one of the following:
-
- - [Configuration Manager](https://docs.microsoft.com/mem/configmgr/core/servers/deploy/configure/configure-role-based-administration)
-
- - [Advanced Group Policy Management](https://docs.microsoft.com/microsoft-desktop-optimization-pack/agpm)
-
- - [Windows Admin Center](https://docs.microsoft.com/windows-server/manage/windows-admin-center/overview)
-
-3. After your roles are defined and RBAC is set up, grant access to the Microsoft Defender Security Center. See [Manage portal access using RBAC](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/rbac).
