Kubernetes security encompasses admission control, network policies, runtime detection, and posture checks across modern multi-cloud security architectures.
The Decision Matrix If this describes you Choose Why Runtime and K8s depth are priorities Sysdig Falco for lineage, deepest runtime Full lifecycle, container-first Aqua for K8s assurance, security scan Buying CNAPP breadth anyway Palo Alto (Prisma Cloud) for K8s on the platform graph Context-first agentless Wiz for correlation across clusters OpenShift estate Red Hat ACS (StackRox) for K8s-native, admission-strong Developer-first shift-left Snyk for CI-manifest scanning Open-source posture, free ARMO (Kubescape) for CNCF posture, free core Network policy and eBPF security Tigera (Calico) for K8s networking-security standard Azure/AKS gravity Microsoft Defender for economics Unified telemetry across estate Uptycs for osquery/eBPF laptop-to-cluster Definitional answer: Kubernetes security protects clusters across admission, network, runtime, and posture checks, plus image and IaC feeding.
