+
+The Helm chart creates a Service named `<release>-appsec-service` in the namespace where CrowdSec is installed. With the default release name `crowdsec` in namespace `crowdsec`, the in-cluster DNS name is:
+
+```
+crowdsec-appsec-service.crowdsec.svc.cluster.local:7422
+```
+
+If you used a different release name or namespace, adjust accordingly: `<release>-appsec-service.<namespace>.svc.cluster.local:7422`.
