 | Premium tier Azure Kubernetes Service cluster        | Cloud resource | High                      | This rule applies to Azure Kubernetes Service clusters with premium tier cluster management. Premium tiers are recommended for running production or mission-critical workloads that need high availability and reliability. |
 | Azure Kubernetes Service cluster with multiple nodes | Cloud resource | High                      | This rule applies to Azure Kubernetes Service clusters with a large number of nodes. This often indicates that the cluster is used for critical workloads, such as production workloads. |
 | Azure Arc Kubernetes cluster with multiple nodes                | Cloud Resource | High                      | This rule applies to Azure Arc Kubernetes clusters with a large number of nodes. This often indicates that the cluster is used for critical workloads, such as production workloads. |
-| Azure Virtual Machine with a Critical User Signed In         | Cloud resource | High                      | This rule applies to virtual machines protected by Defender for Endpoint, where a user with a high or very high criticality level is signed in. The signed-in user can be through a joined or registered device, an active browser session, or other means. |
-|  Key Vaults with Many Connected Identities              | Cloud resource | High                      | This rule identifies Key Vaults that can be accessed by a large number of identities, compared to other Key Vaults. This often indicates that the Key Vault is used by critical workloads, such as production services. |
