+<!-- AUDIENCE: HIGH LEVEL, like a C-level person intro -->
+
+Check first the template (https://github.com/giantswarm/docs/pull/2180/files) it is still on development and you feedback is welcome, but you can take it as a reference.
+
+Concepts come to my mind when I think on security (worthy to mention here without going deep):
+
+- RBAC
+- policies
+- runtime detection
+- cloud security posture
+- image scanning and provenance
+- secret mgmt within the cluster
+- traffic encryption
+
+Write a brief description of the security in general from introductory point of view.
+
+## Features
+
+Describe what use cases are covered by the our security features.
+
+## Cloud-native technologies
+
+- What technologies are used to provide security to the workloads/cluster? (trivy, kyverno, ...)
