 When you offboard a device from Defender for Endpoint, no new detections, vulnerability, or security data are sent to the Microsoft Defender portal. Seven days after offboarding a device, its status changes to [inactive](/defender-endpoint/fix-unhealthy-sensors#inactive-devices). Devices that weren't active within the past 30 days are not factored into your organization's [exposure score](/defender-vulnerability-management/tvm-exposure-score).
