-The SIEM app in Kibana provides an interactive workspace for security teams to
-triage events and perform initial investigations. It enables analysis of
-host-related and network-related security events as part of alert investigations
-or interactive threat hunting.
+Elastic Security combines SIEM threat detection features with endpoint
+prevention and response capabilities in one solution, including:
 
+* A detection engine to identify attacks and system misconfiguration
+* A workspace for event triage and investigations
+* Interactive visualizations to investigate process relationships
+* Embedded case management and automated actions
+* Detection of signatureless attacks with prebuilt {ml} anomaly jobs and
+detection rules
