Container Security

Container security testing finds the weaknesses attackers use to break out of a container, move between workloads or take over a Kubernetes cluster. We review your images, orchestration and runtime configuration from build to deployment and show you exactly how to harden them.

What We Test

• Container images: vulnerable packages, embedded secrets, unnecessary tools and insecure base images.
• Dockerfiles and build pipeline: running as root, exposed ports, unpinned dependencies and registry access.
• Kubernetes configuration: RBAC, service accounts, network policies, pod security settings and namespace isolation.
• Secrets management: how credentials and keys are stored, mounted and rotated.
• Runtime and escape paths: privileged containers, host mounts, kernel capabilities and container-to-host breakout.
• Managed services: EKS, AKS and GKE settings alongside the wider cloud configuration.

Our Approach

1. Scoping: we agree which clusters, namespaces, registries and pipelines are in scope.
2. Configuration review: we compare your setup against recognised hardening benchmarks such as CIS.
3. Hands-on testing: from a compromised-pod starting point, we attempt privilege escalation, lateral movement and cluster takeover.
4. Reporting and retest: prioritised findings with fixes, then verification once you have remediated.

What You Get

• An executive summary of container and cluster risk.
• Technical findings with evidence, severity and specific configuration changes.
• Guidance for adding image scanning and policy checks to your DevSecOps pipeline.

Why Offensium Vault

• Manual, expert-led work: every finding is verified by a tester, not copied from a tool.
• Clear reporting: an executive summary for leadership and step-by-step technical detail for engineers.
• Free retest: we confirm your fixes and issue an updated report.
• ISO/IEC 27001 and ISO 9001 certified processes for handling your data and delivering consistent quality.

Frequently Asked Questions

Do you test self-managed and managed Kubernetes?

Yes. We test self-managed clusters and managed services such as Amazon EKS, Azure AKS and Google GKE.

Will testing disrupt running workloads?

We agree rules of engagement first and avoid destructive actions. Testing can run against a staging cluster if preferred.

Is image scanning enough?

No. Scanning finds known vulnerable packages, but many serious issues are in RBAC, network policy and runtime settings, which need manual review.
