 Cloud Protection is an _optional_ add-on to Security Analytics that provides value-added protection capabilities for cloud assets. Cloud Protection is available in two tiers of carefully selected features to enable common cloud security operations:
 
 * **Cloud Protection Essentials** — Protects your cloud workloads, continuously tracks posture of your cloud assets, and helps you manage risks by detecting configuration issues per CIS benchmarks.
-* **Cloud Protection Complete** — Adds response capabilities and configuration drift prevention for Cloud Workloads.
+* **Cloud Protection Complete** — Adds response capabilities.
 
 Your total cost depends on the number of protected cloud workloads and other billable cloud assets you configure for use with Elastic Cloud Security.

-Provides cloud-native runtime protections for containerized environments by identifying and (optionally) blocking unexpected system behavior in Kubernetes containers. These capabilities are sometimes referred to as container drift detection and prevention. The solution also captures detailed process and file telemetry from monitored containers, allowing you to set up custom alerts and protection rules.
