Results

  • PCI-DSS compliance achieved for shared services infrastructure hosting production payment workloads
  • Production workloads successfully migrated from a non-compliant environment to the new PCI-compliant infrastructure without service disruption
  • SIEM integration with application log routing for full audit trail and compliance evidence
  • Runtime security monitoring for container workloads, providing continuous compliance verification and vulnerability detection
  • Automated TLS certificate management removing manual certificate handling from the operational burden
  • Comprehensive operational runbooks covering service architecture, deployment procedures, known issues, access patterns, and patching - ready for compliance audits
  • Custom Helm charts for all shared services, built to meet specific PCI compliance and operational requirements
  • Infrastructure as Code for repeatable, auditable, version-controlled infrastructure changes

The Problem

A Fortune 500 global payments processor needed to establish PCI-compliant cloud infrastructure for production payment workloads. The existing environment did not meet PCI-DSS requirements:

  • Non-compliant production environment - existing infrastructure was not built to PCI-DSS standards, and production payment workloads needed to be migrated to a compliant setup
  • No SIEM integration - application logs were not being routed to a Security Information and Event Management system, a core PCI requirement
  • No runtime security - no container-level security monitoring or compliance verification in place
  • No operational documentation - compliance audits require detailed runbooks and procedures that did not exist
  • Complex security requirements - PCI-DSS demands specific controls around network segmentation, access management, certificate handling, secrets management, and edge security

What We Delivered

PCI-Compliant Shared Services

Designed and deployed shared services infrastructure on Kubernetes with a focus on open-source CNCF projects. Developed custom Helm charts for each shared service to meet specific compliance and operational requirements. The architecture was built for auditability from day one - every infrastructure change tracked through version control with a clear audit trail.

Security and Compliance Controls

Implemented the full set of security controls required for PCI-DSS: application log routing to the SIEM for audit compliance, identity and access management, automated TLS certificate provisioning, proper network segmentation between environments, edge security for ingress traffic, cloud-native secrets management, and runtime container security monitoring.

Production Migration

Migrated production payment workloads from the non-compliant environment to the new PCI-compliant infrastructure. This required careful coordination to maintain service continuity while ensuring all compliance controls were in place and verified.

CI/CD and Automation

Built CI/CD pipelines for Helm chart mirroring from external sources, container image scanning, image builds with security verification, and infrastructure automation. All pipelines were designed with compliance requirements in mind - providing traceability and security scanning at every stage.

Operational Documentation

Created comprehensive service runbooks covering architecture, build and deployment procedures, known issues and remediation steps, IAM and access patterns, and patching procedures - ensuring the team was audit-ready from day one.
