## Hardware, firmware, and software requirements for Windows Defender Device Guard
To deploy Windows Defender Device Guard in a way that uses all of its virtualization-based security (VBS) features, the computers you are protecting must meet certain hardware, firmware, and software requirements. However, computers lacking some of the hardware and firmware requirements will still receive some protection when you deploy code integrity policies—the difference is that those computers will not be as hardened against certain threats.
To deploy Windows Defender Device Guard in a way that uses all of its virtualization-based security (VBS) features, the computers you are protecting must meet certain hardware, firmware, and software requirements. However, computers lacking some of the hardware and firmware requirements will still receive some protection when you deploy Windows Defender Application Control (WDAC) policies—the difference is that those computers will not be as hardened against certain threats.
For example, hardware that includes CPU virtualization extensions and SLAT will be hardened against malware that attempts to gain access to the kernel, but without protected BIOS options such as “Boot only from internal hard drive,” the computer could be booted (by a malicious person who has physical access) into an operating system on bootable media. For an outline of how VBS-related hardware strengthens the hardening offered by Windows Defender Device Guard, see [Introduction to Windows Defender Device Guard: virtualization-based security and Windows Defender Application Control](introduction-to-device-guard-virtualization-based-security-and-code-integrity-policies.md).
