Announcing public preview: Cilium mTLS encryption for Azure Kubernetes Service

We are thrilled to announce the public preview of Cilium mTLS encryption in Azure Kubernetes Service (AKS) , delivered as part of Advanced Container Networking Services and powered by the Azure CNI dataplane built on Cilium . This capability is the result of a close engineering collaboration between Microsoft and Isovalent (now part of Cisco). It brings transparent, workload ‑ level mutual TLS (mTLS) to AKS without sidecars, without application changes, and without introducing a separate service mesh stack.
