The Device Health Score by Tenant widget is available on the Managed Endpoint Defense - Executive Summary dashboard page. It lists the Aurora Endpoint Defense tenants that you manage with each of their health scores against the score baseline. The default score baseline for all customers is "A". If a tenant's health score is below the baseline, the score is marked in red and tenant's critical escalation group and the Aurora Managed Endpoint Defense team are notified. Scores need to be improved to at least meet the baseline, for example, by updating to the latest agents on the devices registered with the tenant.
