Container Security

Container & Kubernetes
Security Assessment

Containers and Kubernetes make deployment easy, but they also make misconfiguration easy. We test your images, cluster configs, RBAC policies, and runtime environment to find the gaps that let attackers escape containers, escalate privileges, or move laterally across namespaces and nodes.

The Container Security Challenge

Containers let you ship fast, but security configurations don't always keep up. A vulnerable base image gets pulled into 50 services. An overly permissive RBAC role gets copy-pasted across namespaces. A privileged container runs in production because someone forgot to remove a debug flag. These are the issues we look for.

Containerized environments change constantly. Pods scale up and down, images get rebuilt, and configs drift from what was originally reviewed. Automated scanners flag CVEs but miss the real risks: privilege escalation paths through service accounts, RBAC misconfigurations that grant cluster-admin to workloads, and exposed kubelet or API server endpoints. That's where hands-on testing by engineers who understand Kubernetes internals makes the difference.

Our Assessment Approach

Container Image Security

Deep analysis of Docker images including vulnerability scanning, base image security, layer inspection, and identification of embedded secrets, malware, and supply chain risks.

CVE identification in base images and dependencies

Hardcoded secrets and credentials detection

Dockerfile hardening review (multi-stage builds, non-root users, minimal base images)

Kubernetes Cluster Security

Kubernetes security assessment covering RBAC policies, network policies, pod security standards, secrets management, and admission control configurations.

RBAC privilege escalation and excessive permissions

Network policy gaps and pod-to-pod communication

API server security and authentication mechanisms

Runtime Security Testing

Live assessment of running containers and workloads to identify runtime vulnerabilities, container escapes, privilege escalation paths, and resource abuse scenarios.

Container breakout and escape testing

Privileged container exploitation and risk validation

Host filesystem mounts and Docker socket access validation

Secrets & Configuration Management

Evaluation of how secrets and sensitive configuration data are stored, rotated, and accessed across your containerized workloads.

Kubernetes Secrets security and encryption

Environment variable exposure risks

External secrets manager integration review (Vault, AWS Secrets Manager, sealed-secrets)

Network & Ingress Security

Assessment of network segmentation, ingress controller configurations, and service mesh policies that control traffic flow between pods, services, and external endpoints.

Network policy enforcement and pod-level segmentation

Ingress controller misconfigurations and TLS termination

Service mesh policy review (Istio, Linkerd, Cilium)

Container Breaches Are Growing

Container breaches rarely start with a zero-day. They start with a public image running a known CVE, a service account with cluster-admin bound to a default namespace, or a pod with hostNetwork access reaching the Kubernetes API server. These aren't advanced attacks. They're misconfigurations that compound. One overly permissive role leads to secret access, which leads to lateral movement, which leads to node compromise. Container breaches can go undetected for months, giving attackers enough time to exfiltrate data, pivot across clusters, and establish persistence.

Find misconfigurations, escape paths, and RBAC gaps in your Kubernetes environment before they become incidents.
