12 Best Kubernetes Security Tools Compared (2026): Features & Pricing
A buying-guide comparison of twelve Kubernetes security vendors, from free OSS tools like Falco and Kubescape to paid platforms led by Sysdig and Aqua.
The article compares features and pricing mechanics for twelve Kubernetes security vendors including Sysdig, Wiz, Aqua Security, SUSE NeuVector, Snyk, Isovalent (Cisco), Palo Alto Prisma Cloud, Fairwinds, Red Hat ACS (StackRox), and Tigera. It argues CNCF-grade open source (Kubescape, Falco, Calico, NeuVector, Cilium/Tetragon) provides a free floor for posture, runtime, and network policy. Pricing hinges on node-versus-cluster-versus-developer billing units, and Cisco's Isovalent acquisition consolidates the eBPF layer inside a networking giant.
- OSS floor (Kubescape, Falco, Calico, NeuVector, Cilium) covers posture, runtime, and network policy free
- Sysdig and Aqua lead paid runtime and lifecycle security, priced per workload or node
- Cisco's Isovalent acquisition places Cilium and Tetragon eBPF tooling under a networking giant
- Billing unit choice (node, cluster, developer) materially changes vendor quotes
- Organizations
- CNCF

Quick Answer: Kubernetes security quotes hinge on the node-vs-cluster-vs-developer unit choice, and the OSS floor (Kubescape, Falco, Calico, NeuVector, Cilium/Tetragon) resets every negotiation. Sysdig and Aqua lead paid runtime/lifecycle; Cisco (Isovalent) now owns the eBPF network layer; Fairwinds sells governance-as-guardrails; Microsoft Defender publishes the anchor rates.
