+### Does ECI protect containers implicitly used by "docker build"?
+
+Prior to Docker Desktop 4.19, ECI did not protect containers used implicitly
+by `docker build` during the build process.
+
+Since Docker Desktop 4.19, ECI protects containers used by `docker build`
+when using the [docker-container build driver](/manuals/build/builders/drivers/_index.md).
+
+In addition, since Docker Desktop 4.30, ECI also protects containers used by
+`docker build` when using the `docker` build driver (the default driver), on all
+platforms supported by Docker Desktop except Windows with WSL 2.
+
+### Does ECI protect Kubernetes in Docker Desktop?
+
+Prior to Docker Desktop 4.38, ECI did not protect the Kubernetes cluster
+integrated in Docker Desktop.
+
+Since Docker Desktop 4.38, ECI protects the integreated Kubernetes cluster
+when using the new "kind" provisioner (see [Deploy On Kubernetes](../../../../desktop/features/kubernetes.md)).
+In this case, each node in the multi-node Kubernetes cluster is actually an ECI
+protected container. With ECI disabled, each node in the Kubernetes cluster is
+a less-secure fully privileged container.
+
+ECI does not protect the integrated Kubernetes cluster when using the
+older "Kubeadm" provisioner (single-node cluster).
 
 ### Does ECI protect containers launched prior to enabling ECI?
 
-No. Containers created prior to switching on ECI are not protected. Therefore, it is 
+No. Containers created prior to switching on ECI are not protected. Therefore, it is
 recommended you remove all containers prior to switching on ECI.
 
 ### Does ECI affect the performance of containers?
