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.

Duration: 7-10 days Team: 1 Senior K8s Security Consultant + AI Agents

You might be experiencing...

Cluster-admin bound to too many service accounts — no least-privilege
No network policies — every pod can talk to every other pod
Containers running as root with host path mounts and privileged access
Compliance audit coming (SOC2 Type II, HIPAA, PCI-DSS, GDPR) and K8s controls are not mapped

Engagement Phases

Days 1-3

Automated Security Scan

Run CIS Kubernetes Benchmark v1.8 (kube-bench), RBAC audit, pod security analysis, network policy review, image vulnerability scanning.

Days 4-7

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.

Days 8-10

Report & Hardening Guide

Deliver security scorecard, CIS Benchmark results, RBAC audit, and implementation guide with YAML for every fix.

Deliverables

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.
