Kubernetes & Container Security
Security assessment of Kubernetes and container environments covering RBAC, the control plane, workload isolation, runtime controls, secrets and the software supply chain across EKS, AKS and GKE.
Containers and Kubernetes introduce security boundaries that conventional infrastructure reviews may not assess in sufficient depth. We evaluate the environment from an attacker’s perspective, starting from scenarios such as a compromised pod or an over-permissioned service account and tracing possible paths towards the cluster, nodes and protected workloads.
Coverage spans the Kubernetes environment. We review RBAC and the control plane for privilege-escalation paths, pod and workload security for weak isolation and dangerous capabilities, and runtime configuration for container-escape paths to the host. We trace the software supply chain through images, registries and CI/CD pipelines, look for exposed secrets and assess whether network policies segment internal traffic as intended. Testing is benchmarked against the CIS Kubernetes Benchmark for EKS, AKS and GKE.
The assessment is led by security engineers and combines automated checks with manual validation. You receive findings validated through controlled exploitation where appropriate, rated by practical impact, mapped to relevant CIS controls and MITRE ATT&CK for Containers, with remediation guidance and an option to re-test completed fixes.

How it works
-
01
Scoping & access
Identify clusters, platforms (EKS/AKS/GKE), critical workloads and the access or assumed-breach starting point.
-
02
Configuration baseline
Benchmark the control plane, RBAC, workloads and network policies against the CIS Kubernetes Benchmark.
-
03
Attack-path testing
Attempt privilege escalation, container escape and lateral movement from a compromised-pod foothold.
-
04
Supply-chain & secrets review
Assess images, registries and CI/CD pipelines for tampering and exposed secrets.
-
05
Reporting & hardening
Risk-rated findings mapped to CIS and MITRE ATT&CK, with concrete hardening guidance.
-
06
Re-test
Re-test remediated clusters to confirm fixes and closure (optional).

Frequently asked questions
How is this different from a standard cloud security or configuration review?
A cloud-posture review assesses provider-level configuration such as IAM, storage and networking. A Kubernetes assessment goes inside the cluster and covers the control plane, RBAC, workload security, network policies, nodes and the container supply chain. Where authorised, controlled attack-path testing can validate whether a compromised workload could lead to privilege escalation, lateral movement or access outside the intended boundary.
Do you support managed Kubernetes like EKS, AKS and GKE?
Yes. We assess Amazon EKS, Azure AKS and Google GKE as well as self-managed and on-premises clusters. For managed services, the review distinguishes provider responsibilities from the RBAC, workloads, network policies, node configuration and integrations that remain under the customer’s control.
Which standards and frameworks do you test against?
We baseline against the CIS Kubernetes Benchmark and the platform-specific CIS guides for EKS, AKS and GKE, and we map attacker activity to MITRE ATT&CK for Containers. We also align with NSA/CISA Kubernetes hardening guidance and Pod Security Standards, so findings map both to a recognised control and to the real technique an adversary would use.
Will testing destabilise our running clusters?
Configuration and RBAC review is normally read-only and low impact. Active attack-path testing carries controlled operational risk, so it is explicitly scoped, scheduled and subject to stop conditions. A representative non-production cluster is preferred where feasible; production testing uses agreed safety limits and immediate escalation for critical findings.
What do we receive, and can you re-test after we fix the findings?
You receive risk-rated findings proven by exploitation, each mapped to the CIS control it breaches and to MITRE ATT&CK for Containers, with concrete hardening guidance for your platform team and an executive summary. Re-testing after remediation is available to confirm closure, and Enterprise engagements can integrate checks into your CI/CD pipeline so regressions are caught before they ship.
