kguardian

kguardian-dev

73stars
kguardian preview

A Kubernetes tool leveraging eBPF for advanced Kubernetes security, auto-generating Network Policies, Seccomp Profiles, and more.

  • Network Policy generation — least-privilege Kubernetes NetworkPolicy and Cilium CiliumNetworkPolicy resources from observed pod-to-pod traffic. Each flow's peer is identified when it is captured, not when a policy is generated, so a recycled pod IP never allow-lists the wrong workload (how peers are attributed).
  • Policy auditing before enforcement — the AuditNetworkPolicy CRD is byte-identical to an upstream NetworkPolicy, but instead of dropping packets the evaluator reports every flow the policy would deny. Ship policies with confidence instead of blackholing production.
