Zero Trust Kubernetes Security
By default, every pod in a Kubernetes cluster can communicate with every other pod. That is the opposite of zero trust. Anubiz Engineering implements zero trust inside your clusters — pod identity verification, mutual TLS on every connection, NetworkPolicy enforcement, and admission controllers that prevent insecure workloads from deploying.

We implement, you ship. Async, documented, done in days.
Pod Identity with SPIFFE/SPIRE
Every pod gets a cryptographic identity through SPIFFE (Secure Production Identity Framework For Everyone). SPIRE issues short-lived X.509 certificates that identify each workload. Service mesh sidecars or application code use these identities for mutual authentication. No more relying on Kubernetes service accounts for inter-service auth — pod identity is cryptographically verifiable and automatically rotated.
Service Mesh mTLS
We deploy Istio, Linkerd, or Cilium service mesh with strict mTLS mode. Every connection between pods is encrypted and mutually authenticated. The mesh handles certificate issuance, rotation, and verification transparently — application code does not change. Services that attempt plaintext communication are rejected. mTLS enforcement is applied per-namespace during migration and cluster-wide once all services are onboarded.
NetworkPolicy and Authorization
Kubernetes NetworkPolicies implement L3/L4 segmentation: each namespace and pod can only communicate with explicitly declared peers. Service mesh authorization policies add L7 control: the API service can call the database service only via specific HTTP methods and paths. Combined, these layers ensure that even if an attacker compromises a pod, lateral movement is blocked at both network and application layers.
Admission Control
We deploy OPA Gatekeeper or Kyverno to enforce security policies at admission time. Pods must run as non-root, must not use hostNetwork, must have resource limits, must not mount sensitive host paths, and must have security contexts defined. Images must come from approved registries and pass vulnerability scanning. Non-compliant workloads are rejected before they ever run — zero trust starts at deployment time.
