 For an Azure environment activated on an Azure subscription, Azure Security Center will automatically discover IaaS resources that are deployed within the subscription.
 
-> [!NOTE]
-> To receive the full set of security features, you must have the [Log Analytics Agent](../azure-monitor/platform/agents-overview.md#log-analytics-agent), which is used by Azure Security Center, installed and [properly configured to send data to Azure Security Center](security-center-enable-data-collection.md#manual-agent).

 Virtual machines are also created in a customer subscription as part of some Azure managed services as well, such as Azure Kubernetes (AKS), Azure Databricks, and more. These virtual machines are also discovered by Azure Security Center, and the Log analytics agent can be installed and configured according the supported [Windows/Linux operating systems](#os-windows), listed above.
