Security Exposure Management provides an out-of-the-box catalog of predefined critical asset classifications for assets that include devices, identities, and cloud resources.
You can review and classify critical assets, turning them on and off as needed.

We also utilize criticality context retrieved from external data connectors. This context will be presented as classifications in the predefined critical asset management classification library.
Device
| Classification | Asset type | Default criticality level | Description |
|---|---|---|---|
| Microsoft Entra ID Connect | Device | High | The Microsoft Entra ID Connect (formerly known as AAD Connect) server is responsible for syncing on-premises directory data and passwords to the Microsoft Entra ID tenant. |
| ADCS | Device | High | ADCS server allows administrators to fully implement a public key infrastructure (PKI) and issue digital certificates that can be used to secure multiple resources on a network. Moreover, ADCS can be used for various security solutions, such as SSL encryption, user authentication, and secure email. |
| ADFS | Device | High | ADFS server provides users with single sign-on access to systems and applications located across organizational boundaries. It uses a claims-based access control authorization model to maintain application security and implement federated identity. |
| Backup | Device | Medium | Backup server is responsible for safeguarding data through regular backups, ensuring data protection and disaster recovery readiness. |
| Domain Admin Device | Device | High | Domain admin devices are devices that one or more of the domain admins are frequently logged into. These devices are likely to store related files, documents, and credentials used by the domain admins. Note: We apply a logic to identify devices belonging to an admin based on multiple factors, including the frequent usage of administrative tools. |
| Domain Controller | Device | Very High | Domain controller server is responsible for user authentication, authorization, and centralized management of network resources within an active directory domain. |
| DNS | Device | Low | The DNS server is essential for resolving domain names to IP addresses, enabling network communication and access to resources both internally and externally. |
| Exchange | Device | Medium | Exchange server is responsible for all the mail traffic within the organization. Depending on the setup and architecture, each server might hold several mail databases that store highly sensitive organizational information. |
| IT Admin Device | Device | Medium | Critical devices used to configure, manage, and monitor the assets within the organization are vital for IT administration and are at high risk of cyber threats. They require top-level security to prevent unauthorized access. Note: We apply a logic to identify devices belonging to an admin based on multiple factors, including the frequent usage of administrative tools. |
| Network Admin Device | Device | Medium | Critical devices used to configure, manage, and monitor the network assets within the organization are vital for network administration and are at high risk of cyber threats. They require top-level security to prevent unauthorized access. Note: We apply a logic to identify devices belonging to an admin based on multiple factors, including the frequent usage of administrative tools. |
| VMware ESXi | Device | High | The VMware ESXi hypervisor is essential for running and managing virtual machines within your infrastructure. As a bare-metal hypervisor, it's providing the foundation for creating and managing virtual resources. |
| VMware vCenter | Device | High | The VMware vCenter Server is crucial for managing virtual environments. It provides centralized management of virtual machines and ESXi hosts. If it fails, it could disrupt the administration and control of your virtual infrastructure, including provisioning, migration, load balancing of virtual machines, and datacenter automation. However, as there are often redundant vCenter Servers and High Availability configurations, the immediate halt of all operations might not occur. Its failure could still cause significant inconvenience and potential performance issues |
| Hyper-V Server | Device | High | The Hyper-V hypervisor is essential for running and managing virtual machines within your infrastructure, serving as the core platform for their creation and management. If the Hyper-V host fails, it can lead to the unavailability of hosted virtual machines, potentially causing downtime and disrupting business operations. Moreover, it can result in significant performance degradation and operational challenges. Ensuring the reliability and stability of Hyper-V hosts is therefore critical for maintaining seamless operations in a virtual environment. |

Cloud resource
| Classification | Asset type | Default criticality level | Description |
|---|---|---|---|
| Databases with Sensitive Data | Cloud resource | High | This is a data store that contains sensitive data. Sensitivity of data can range from secrets, confidential documents, personally identifiable information, and more. |
| Confidential Azure Virtual Machine | Cloud resource | High | This rule applies to Azure confidential virtual machines. Confidential VMs provide increased isolation, privacy, and encryption, and are used for critical or highly sensitive data and workloads. |
| Locked Azure Virtual Machine | Cloud resource | Medium | This is a virtual machine that is safeguarded by a lock. Locks are used to protect assets from deletion and modifications. Usually, administrators use locks to safeguard critical cloud assets in their environment, and to protect them from accidental deletion and unauthorized modifications. |
| Azure Virtual Machine with High Availability and Performance | Cloud resource | Low | This rule applies to Azure virtual machines that use premium Azure storage and are configured with an availability set. Premium storage is used for machines with high performance requirements, such as production workloads. Availability sets improve resilience and are often indicated for business critical VMs that need high availability. |
| Immutable Azure Storage | Cloud resource | Medium | This rule applies to Azure storage accounts that have immutability support enabled. Immutability stores business data in a write once read many (WORM) state, and usually indicates that the storage account holds critical or sensitive data that must be protected from modification. |
| Immutable and Locked Azure Storage | Cloud resource | High | This rule applies to Azure storage accounts that have immutability support enabled with a locked policy. Immutability stores business data in a write once read many (WORM). Data protection is increased with a locked policy to ensure that data can’t be deleted or its retention time shortened. These settings usually indicate that the storage account holds critical or sensitive data that must be protected from modification or deletion. Data might also need to align with compliance policies for data protection. |
| 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. |
