 [Cross-cluster search](../../search/cross-cluster-search.md) is an {{es}} feature that allows one cluster (the *local* cluster) to query data in a separate cluster (the *remote* cluster). {{elastic-sec}}'s detection rules can perform a cross-cluster search to query data in remote clusters.
 
+::::{admonition} Requirements
+* To learn about the requirements for using cross-cluster search in the {{stack}}, refer to [Cross-cluster search](../../search/cross-cluster-search.md). 
+* Using cross-cluster search for {{esql}} rules in the {{stack}} requires an [Enterprise subscription](https://www.elastic.co/pricing).
