For a global oil and gas organisation, achieving and maintaining PCI compliance across its USA and EMEA operations was becoming increasingly complex. Their existing PCI auditing system lacked the visibility, scalability, and automation required to meet evolving compliance demands.

To modernise, they set out to replace their legacy QRadar platform with Splunk, aiming to gain complete, end-to-end visibility into PCI-DSS compliance data. But the business lacked the in-house expertise to build, manage, and continuously optimise a Splunk environment at this scale.

They needed a trusted partner who could deliver a robust platform, ensure ongoing operational excellence, and align everything to PCI-DSS standards.

The approach

They took full ownership of the Splunk environment, from initial migration to ongoing management. Working closely with their PCI department, they designed, deployed, operated a fully managed service that ensured continuous compliance visibility and operational stability.

Building the Foundation

  • Migrated from QRadar to Splunk, architecting a scalable and resilient platform purpose-built for PCI compliance.
  • Onboarded diverse data sources across cloud, endpoint, identity, and network environments.
  • Developed and tuned use cases, correlation searches, and dashboards to enable end-to-end monitoring of PCI-relevant activities.

Managing the Platform

  • Provided engineering ownership to ensure platform uptime, performance, and scalability.
  • Continuously monitored ingestion pipelines to detect anomalies, latency, or data loss in real time.
  • Performed regular upgrades, health checks, and optimisation of query performance and storage tiers.
  • Embedded robust governance through RBAC controls, audit trails, and documented operational runbooks.
  • Delivered ongoing KPI tracking, reporting, and alignment to the PCI-DSS framework.

Optimising for Continuous Compliance

  • Integrated automation for reliability and rapid remediation.
  • Maintained a proactive improvement cycle through quarterly service reviews and roadmap alignment.
  • Collaborated with the client’s compliance and SOC teams to refine detections, analytics, and operational insights.

The outcomes

By embedding deep Splunk expertise within a managed service model, we enabled this leading oil and gas company to achieve PCI compliance with confidence, efficiency, and visibility. Outcomes included:

  • Sustained PCI compliance – continuous monitoring and reporting ensured full visibility into compliance across regions.
  • Zero unplanned downtime – platform stability and proactive maintenance kept critical systems running smoothly.
  • Expert oversight – platform management by certified engineers removed the burden from internal teams.
  • Freed internal capacity – the client’s teams now focus on other activities such as developing insights and detection use cases, rather than maintenance.
  • Confidence in compliance posture – consistent, validated data ingestion and detection accuracy strengthened audit readiness.
