Harden Your Clusters Before Attackers Find the Gaps
Comprehensive K8s security assessment against CIS Kubernetes Benchmark v1.8, NIST SP 800-190, and your compliance framework — with a hardening implementation guide that includes copy-paste YAML for every fix.
You might be experiencing...
Engagement Phases
Automated Security Scan
Run CIS Kubernetes Benchmark v1.8 (kube-bench), RBAC audit, pod security analysis, network policy review, image vulnerability scanning.
Analysis & Compliance Mapping
Score 8 security domains, map findings to SOC2 Type II, ISO 27001, NIST SP 800-190, and CIS Benchmark controls. Rank findings by severity and build hardening guide.
Report & Hardening Guide
Deliver security scorecard, CIS Benchmark results, RBAC audit, and implementation guide with YAML for every fix.
Deliverables
Before & After
| Metric | Before | After |
|---|---|---|
| CIS Benchmark Compliance | 55-65% passing | 90%+ passing |
| Cluster-Admin Bindings | 8-15 service accounts | 1-2 (break-glass only) |
| Network Policy Coverage | 0% of namespaces | 100% default-deny |
| Containers Running as Root | 40-60% | <5% (system only) |

Frequently Asked Questions
How long does K8s security hardening take?
The assessment and hardening guide runs 7-10 days. Days 1-3 cover automated CIS Benchmark scanning, RBAC audit, and vulnerability analysis. Days 4-7 handle analysis and compliance mapping. Days 8-10 deliver the security scorecard and hardening implementation guide with copy-paste YAML for every fix.
Do you map findings to compliance frameworks like SOC2, HIPAA, or PCI-DSS?
Yes. We map all Kubernetes security findings to SOC2 Type II controls, HIPAA workload isolation requirements, PCI-DSS network segmentation requirements, ISO 27001, and CIS Kubernetes Benchmark v1.8. This gives your compliance team a clear picture of how cluster security posture relates to your regulatory obligations.
What does the RBAC audit cover?
We identify all over-permissioned ClusterRoleBindings and RoleBindings, service accounts with cluster-admin access, and unused or stale RBAC entries. Every finding includes a specific recommendation to implement least-privilege access. Typical clusters have 8-15 service accounts with excessive permissions.
Will the hardening changes cause application downtime?
The assessment itself is read-only and non-invasive. The hardening guide provides implementation YAML that you can apply incrementally. We recommend starting with non-production clusters and testing thoroughly. Network policy changes, in particular, should be applied namespace by namespace.
What is included in the hardening implementation guide?
You receive copy-paste YAML for every finding: network policy templates with default-deny, pod security standards, RBAC corrections, image vulnerability remediation steps, and CIS Benchmark fixes. Every fix includes a severity rating, effort estimate, and expected security impact.
How do you address HIPAA workload isolation requirements?
For HIPAA workloads, we implement namespace-level isolation with network policies, pod security admission controls that prevent privileged containers, RBAC restrictions limiting access to PHI-adjacent services, and audit logging for all access to sensitive namespaces. We provide a HIPAA control mapping document for your compliance documentation.
