+title: Ensure that Advanced Cluster Security (ACS) Sensor is deployed
+
+description: |-
+  Red Hat Advanced Cluster Security (ACS) for Kubernetes provides comprehensive security
+  for containerized environments. It offers deep visibility into deployed resources
+  across Kubernetes clusters, enabling teams to detect vulnerabilities in all images,
+  manage compliance, and enforce security policies. By integrating ACS into the Kubernetes
+  environment, organizations can automate security checks and configurations, ensuring that every
+  deployed application is scanned and secured according to best practices and organizational policies.
+
+  Sensor is the service responsible for analyzing and monitoring the cluster. Sensor
+  listens to the OpenShift Container Platform or Kubernetes API and Collector events
+  to report the current state of the cluster. Sensor also triggers deploy-time and
+  runtime violations based on RHACS Cloud Service policies. In addition, Sensor is
+  responsible for all cluster interactions, such as applying network policies,
+  initiating reprocessing of RHACS Cloud Service policies, and interacting with
+  the Admission controller.
+
+
+rationale: |-
+  ACS provides a method to continuously monitor and protect the Kubernetes environment against vulnerabilities
+  and misconfigurations. This ensures that the infrastructure and applications are compliant
+  with security standards and regulations, reducing the risk of security breaches.
