Documented Cloud-Native Security Consultancies
Kubernetes incidents live below the node. Pod-level attack paths, container escapes, and admission-control gaps do not show up in disk images, they show up in runtime telemetry, which is why cluster forensics is a distinct discipline with its own tooling (eBPF, Falco, Tetragon).
The consultancies below are verified on documented CKS staff counts, platform experience, and hands-on tooling, not logo walls. Platform teams get responders who can preserve cluster state while reconstructing what actually ran.

What a cluster-scoped audit covers
Control plane hardening, RBAC review, network policy coverage, admission control posture, secrets handling, and workload escape analysis. CKS-certified staff matter because the certification tests exactly this surface, and staff counts predict whether your engagement gets certified engineers or junior staff learning on your clusters.
Runtime security that stands up in an incident
Falco and eBPF-based tooling (Tetragon, Tracee) records syscall-level truth that post-hoc logs cannot. Directory records show which firms deploy and tune runtime tooling versus which merely list it, the difference matters when you need a defensible timeline.
Supply chain and GitOps
Your pipeline is part of your cluster perimeter. Verified firms trace deployed artifacts to signed builds (Sigstore, SLSA attestations), diff SBOMs between releases, and contain through the GitOps control plane (Argo CD, Flux) rather than manual kubectl, so the attacker redeploy path closes.
Admission control as prevention
The cheapest incident is the one blocked at the API server. Firms here build OPA Gatekeeper and Kyverno policy that stops vulnerable images, unpinned tags, and privileged workloads before they schedule, and post-incident, they close the exact admission gap the attacker used.
Frequently asked questions
What does CKS certification actually prove?
The CNCF Certified Kubernetes Security Specialist exam is hands-on: cluster hardening, admission control, system hardening, minimization, and runtime security tasks performed against live clusters. It is the strongest available signal for cluster security competence, which is why the directory counts holders, not logos.
Do we need eBPF forensics or are logs enough?
For pod-level attack paths, often not. Audit logs show API actions; eBPF telemetry shows syscall-level execution, fileless execution, hidden processes, network behavior that never touched the API server. Verified eBPF-capable firms are flagged in the directory.
Managed or self-managed clusters, does it change the firm we need?
Yes. Managed control planes (EKS, GKE, AKS) limit your forensic surface to what the provider exposes; self-managed clusters give you etcd and node-level access that requires deeper systems engineering. The platform filter matches firms to your footprint.
What does a cloud-native security RFP include?
Cluster and node counts, managed services in use, workload profile (multi-tenant, stateful, GPU), security tooling already deployed (CSPM, CWPP, admission, mesh, secrets), and incident SLA expectations. About 15 minutes to complete.
