Implementing mTLS in Kubernetes clusters: a hands-on guide
Kubernetes ships zero built-in encryption for pod-to-pod traffic — here's how cert-manager and service meshes fix that, and the five misconfigurations that quietly undo it.
How to set up mutual TLS (mTLS) between microservices
A step-by-step guide to configuring mTLS across microservices with Istio — from CA setup and PeerAuthentication policies to certificate rotation and verification.
Sidecar Proxies and the Expanding Attack Surface of Servi...
Sidecar proxies like Envoy quietly double your cluster's attack surface. Real CVEs from 2023–2024 show how mesh sidecars get exploited — and how to actually secure them.
Service Mesh for Supply Chain Policy Enforcement
Using Istio, Linkerd, and Cilium service mesh to enforce signed-artifact, SPIFFE identity, and provenance-aware policy in production clusters.
Kubernetes Service Mesh Policy Depth
Service meshes promise layered policy. The promise is real, but the layers only help if you use them, and most deployments use one.
Service Mesh mTLS Configuration: Getting Mutual TLS Right
Service meshes promise automatic mTLS. The reality involves permissive modes, certificate management complexity, and gaps that attackers can exploit.
