π‘οΈπͺπ»ππβοΈGroup - VBS Incompatible Devices
What this group is forβ
This is a static assigned device group that carves an exception out of the tenant-wide virtualization-based security policy.
It works only as a pair with:
- π§±πͺπ»ES - Memory Integrity and Credential Guard: the default protection this group is excluded from.
- π§±πͺπ»πES - Memory Integrity and Credential Guard - Disable: the inverse policy assigned to this group, which turns VBS back off.
A device lands here only because it genuinely cannot run VBS: an unsigned kernel driver Memory Integrity rejects, a legacy authentication path Credential Guard breaks, or hardware without the required support. Membership is a technical necessity, not a preference.

| Group name | π‘οΈπͺπ»ππβοΈGroup - VBS Incompatible Devices |
| Group description | Devices that cannot run virtualization-based security (Memory Integrity / Credential Guard) due to an incompatible driver or unsupported hardware. Membership requires a documented technical reason and should be temporary. |

β οΈ Governanceβ
Excluding a device from the enable policy is only half the job; the inverse policy is what actually returns it to a working state, so both assignments must be in place. And because you are removing a strong defense from the device, the bar is high:
- A documented technical reason per device (which driver, which dependency, which hardware limit).
- A path back: the plan to fix or replace the blocker so the device can rejoin VBS.
- A regular membership review (quarterly at least). An exception that never expires is a hole, not an exception.
Good reason: a workstation with a critical unsigned driver from a vendor that has not shipped an HVCI-compatible version yet. Bad reason: "it was easier to turn it off everywhere." If you cannot defend a device's place here in an audit, it does not belong here.

Keep it small and keep it temporary. Every device here is one that should be working its way back to protected. π
