 ### Configure HWC for Enterprise Security Package (ESP) clusters
 
 The Enterprise Security Package (ESP) provides enterprise-grade capabilities like Active Directory-based authentication, multi-user support, and role-based access control for Apache Hadoop clusters in Azure HDInsight. For more information on ESP, see [Use Enterprise Security Package in HDInsight](../domain-joined/apache-domain-joined-architecture.md).
