Zero-Trust Cloud Security Architecture for Enterprise Scale

Why Perimeter Security is Obsolete

Modern cloud topologies span multiple public clouds, edge locations, and remote worker endpoints. Relying on traditional VPNs or simple perimeter firewalls creates vulnerable internal surfaces once an initial breach occurs.

Zero-Trust enforces strict identity verification for every single inter-service request, whether coming from outside or inside the cluster.

Micro-Segmentation in Kubernetes Clusters

Utilizing eBPF-powered network policies (such as Cilium), security engineers can restrict pod-to-pod communication at Layer 7. Even if an attacker gains access to a web front-end container, lateral movement to internal database pods is blocked by policy.
