To enable VBS, you can download and use [the hardware readiness tool on the Microsoft Download Center](https://www.microsoft.com/en-us/download/details.aspx?id=53337), or follow the procedures in this topic.
2. **Verify that hardware and firmware requirements are met**. Verify that your client computers possess the necessary hardware and firmware to run these features. A list of requirements for hardware-based security features is available in [Hardware, firmware, and software requirements for Windows Defender Device Guard](requirements-and-deployment-planning-guidelines-for-device-guard.md#hardware-firmware-and-software-requirements-for-device-guard).
