Enforce Zero-Trust Egress in Kubernetes with Native NetworkPolicies
Most teams lock down inbound traffic but leave outbound uncontrolled, creating a risk of data exfiltration. This guide shows how to implement zero-trust egress using Kubernetes NetworkPolicy objects, denying all outbound traffic by default and explicitly allowing only required connections. It covers prerequisites like CNI enforcement and step-by-step YAML configuration for any compliant cluster.
