CKS-Certified Offensive Security
Kubernetes Penetration Testing: Find Vulnerabilities Before Attackers Do
We simulate real attacks against your Kubernetes clusters to find exploitable vulnerabilities. CKS-certified security engineers test container escapes, privilege escalation, and lateral movement.

Your Kubernetes Cluster Looks Secure. But Is It Really?
Configuration reviews tell you what should work. Penetration testing tells you what actually does. Default Kubernetes configurations are notoriously permissive, and even hardened clusters often have exploitable gaps that only active testing reveals.
Our Kubernetes penetration testing simulates real-world attack scenarios—container escapes, privilege escalation, lateral movement, API server exploitation, and supply chain attacks. CKS-certified security engineers use the same techniques that real attackers would use.
Whether you're running AWS EKS, Azure AKS, Google GKE, or self-managed clusters, our cybersecurity team finds the vulnerabilities that configuration reviews miss.
Configuration Review vs. Penetration Testing
Why both are needed for real security
Active testing reveals exploitable vulnerabilities that reviews alone cannot find.
Configuration Review Only
- Configs look correct on paper
- Unknown container escape risks
- RBAC appears properly configured
- Network policies exist
- Secrets seem protected
- Compliance checkbox ticked
With Penetration Testing
- Verified through actual exploitation attempts
- Container isolation tested with real escape techniques
- Privilege escalation paths identified and validated
- Lateral movement tested to verify policy effectiveness
- Secret exposure tested from multiple attack vectors
- Real-world security validated with evidence
Penetration Testing Coverage
Comprehensive offensive security testing for Kubernetes
Cluster Infrastructure Pen Testing
Simulate attacks against your Kubernetes control plane, API server, etcd, kubelet, and node infrastructure. We test for privilege escalation, unauthorized API access, and misconfigured admission controllers.
- API server attack simulation
- etcd & control plane testing
- Kubelet exploit assessment
- Admission controller bypass testing
Container Escape & Runtime Testing
Test container isolation, attempt container escapes, and evaluate runtime security controls. We assess Pod Security Standards enforcement, seccomp profiles, and Falco runtime detection effectiveness.
- Container escape attempts
- Privilege escalation testing
- Seccomp & AppArmor evaluation
- Runtime detection validation
Network & Lateral Movement Testing
Test network segmentation, attempt lateral movement between pods and namespaces, and evaluate network policy effectiveness. We assess ingress security, service mesh controls, and egress restrictions.
- Lateral movement simulation
- Network policy bypass testing
- Ingress & egress testing
- Service mesh security validation
Supply Chain & Secrets Testing
Evaluate container image supply chain security, test secrets exposure, and assess CI/CD pipeline security. Our cybersecurity services include image registry security, secret management, and RBAC exploitation testing.
- Image supply chain assessment
- Secrets exposure testing
- CI/CD pipeline security review
- RBAC exploitation attempts

Our Penetration Testing Process
Structured offensive security methodology
-
Scoping & Rules of Engagement
Define testing scope, boundaries, timing, and communication protocols. Establish rules of engagement to protect production systems while enabling thorough testing.
-
Reconnaissance & Enumeration
Map the attack surface, enumerate exposed APIs, scan container images, and identify potential entry points and misconfigurations.
-
Exploitation & Testing
Execute controlled attacks including container escapes, privilege escalation, lateral movement, secrets extraction, and supply chain attacks.
-
Reporting & Remediation
Deliver detailed vulnerability report with attack narratives, CVSS scores, and remediation guidance. Optional retest to validate fixes.

Kubernetes Penetration Testing FAQs
Common questions about our pen testing services
What is Kubernetes penetration testing?
Kubernetes penetration testing simulates real-world attacks against your cluster infrastructure, containers, and applications to find exploitable vulnerabilities. Unlike a security audit that reviews configurations, penetration testing actively attempts to exploit weaknesses.
Will penetration testing affect our production systems?
We work with you to define safe testing boundaries and timing. Most tests are conducted in staging or non-production environments. When production testing is required, we use controlled, non-destructive techniques and coordinate closely with your team.
What's the difference between a security audit and penetration testing?
A Kubernetes security audit reviews configurations and policies against best practices. Penetration testing goes further by actively attempting to exploit vulnerabilities, simulating how a real attacker would compromise your cluster. We recommend both for comprehensive security.
How often should we conduct penetration testing?
We recommend Kubernetes penetration testing annually, after major architecture changes, before compliance audits, and after significant version upgrades. For continuous security, our managed services include ongoing security monitoring.
What qualifications do your pen testers have?
Our penetration testers hold CKS (Certified Kubernetes Security Specialist) certifications along with offensive security credentials. They combine Kubernetes-specific expertise with cybersecurity experience across cloud-native environments.
