Container & Kubernetes Security
Secure the modern stack. CIS Kubernetes Benchmark assessments, RBAC privilege analysis, container image supply chain security, and service mesh mTLS validation — for EKS, AKS, GKE, and self-managed clusters.
Kubernetes · Containers · Service Mesh
End-to-end security coverage from cluster hardening and RBAC through container supply chain and zero-trust service connectivity.
K8s Cluster Hardening
Deep security assessment of your Kubernetes clusters — auditing control plane configurations, worker node hardening, RBAC policies, and admission controllers against CIS Kubernetes Benchmarks.
- K8s control plane CIS Benchmark audit
- RBAC over-permission analysis
- Network policy coverage and gap review
- Admission controller (OPA/Gatekeeper) assessment
Image & Registry Security
Securing the container supply chain from the Dockerfile through CI/CD pipeline to production registry — ensuring every image deployed is free of critical vulnerabilities and built from hardened base images.
- Dockerfile best practice review
- Container image vulnerability scanning
- Registry access control and signing
- Runtime anomaly detection (Falco/Sysdig)
Service Mesh Security
Security review of your Istio, Linkerd, or Consul Connect configuration — ensuring mutual TLS is enforced between all services and traffic policies correctly implement zero-trust networking principles.
- mTLS configuration and enforcement review
- Sidecar proxy security assessment
- Traffic management and authorization policies
- Egress gateway and external access controls
Kubernetes Complexity Creates Hidden Attack Paths
Kubernetes is powerful — and that power creates attack surface. Misconfigured RBAC, overly permissive service accounts, and unrestricted pod-to-pod communication provide attackers with the lateral movement paths they need after gaining initial access.
Our container and Kubernetes security assessment systematically maps every attack path — from compromised pod to cluster-admin — and delivers a prioritized roadmap to close each one.
RBAC Attack Paths
Mapping privilege escalation routes from pod to cluster-admin.
Image Vulnerabilities
Identifying critical CVEs in production container images.
Pod Escape Risks
Detecting dangerous container configurations enabling host access.
East-West Exposure
Identifying unrestricted pod communication enabling lateral movement.
5-Phase Container Security Assessment
From cluster enumeration and CIS benchmarking through RBAC analysis, supply chain review, and the hardening roadmap.
Cluster Enumeration & Architecture Review
We enumerate all Kubernetes clusters (EKS, AKS, GKE, OpenShift, self-managed) and understand the architectural decisions — node pools, namespaces, workload types, and networking model — before beginning technical assessment.
CIS Benchmark Assessment
Automated and manual assessment of all cluster components against the CIS Kubernetes Benchmark — control plane components, etcd configuration, kubelet settings, and API server security parameters.
RBAC & Policy Analysis
Deep review of RBAC configurations — ClusterRoles, Roles, RoleBindings, and ClusterRoleBindings — identifying over-privilege, dangerous default service account permissions, and paths to cluster-admin escalation.
Supply Chain & Runtime Review
Container image scanning of all deployed images for known CVEs and malware. Runtime security configuration review using Falco rules or existing CWPP agents. Admission controller policy audit.
Findings Report & Hardening Roadmap
Comprehensive report with CIS Benchmark compliance status, RBAC attack path visualizations, image vulnerability register, and a phased hardening roadmap with Helm chart and manifest remediation guidance.
End-to-End Container Security Coverage
From RBAC privilege mapping and network policies through image scanning, admission controllers, secrets management, and service mesh.
RBAC Privilege Analysis
Identifying excessive ClusterRole permissions, bound service accounts with cluster-wide access, and RBAC misconfiguration paths leading to cluster-admin access.
Network Policy Coverage
Mapping all pod-to-pod communication paths and identifying workloads that lack any Kubernetes Network Policy — leaving them open to unrestricted east-west traffic.
Image Vulnerability Scanning
Scanning all container images running in production for critical and high CVEs — with prioritization based on exploitability and whether a fix is available.
Admission Controllers
Review of OPA/Gatekeeper, Kyverno, or PodSecurityAdmission configurations to ensure policy guardrails are correctly preventing deployment of insecure configurations.
Secrets Management
Identifying plaintext secrets in ConfigMaps, environment variables, or poorly configured etcd encryption — and evaluating integration with external secrets platforms.
Service Mesh mTLS Audit
Verifying that mutual TLS is correctly enforced in STRICT mode across all service-to-service communication paths — identifying services running in PERMISSIVE mode.
CKS-Certified Kubernetes Expertise
Our engineers hold Certified Kubernetes Security Specialist certifications and have assessed complex multi-cluster production Kubernetes environments across all major cloud providers.
K8s-Native Expertise
Our engineers hold CKS (Certified Kubernetes Security Specialist) certifications and have deep, hands-on experience assessing EKS, AKS, GKE, and self-managed Kubernetes clusters across complex production environments.
Supply Chain Focus
We assess the full container supply chain — from base image selection and Dockerfile through CI/CD pipeline image handling to production registry access control — not just the running cluster.
RBAC Attack Path Visualisation
We use graph-based analysis of RBAC configurations to identify non-obvious privilege escalation paths to cluster-admin — presented visually in findings for easy understanding.
Manifest Remediation
Our remediation guidance includes actual Helm chart values, Kubernetes manifest patches, and OPA/Gatekeeper policy templates — not just text descriptions of what needs to change.
