A global oil and gas organisation sought to tackle the growing complexity of achieving and maintaining PCI compliance across its USA and EMEA operations. The existing PCI auditing system fell short in terms of visibility, scalability, and automation, making compliance efforts challenging.
To modernise, the company set out to replace its legacy QRadar platform with Splunk, aiming for comprehensive visibility into PCI-DSS compliance data. However, lacking in-house expertise to build and manage a Splunk environment of this magnitude, they required a trusted partner to deliver a robust platform, ensuring ongoing operational excellence and alignment with PCI-DSS standards.
Strategic approach
Organisation assumed full duty for the Splunk setting, covering everything from initial migration to serial
The organisation assumed full responsibility for the Splunk environment, covering everything from initial migration to continuous management.
Collaborating closely with their PCI department, they designed and deployed a fully managed service, delivering uninterrupted compliance visibility and operational stability.
Building the foundation
The transition involved migrating from QRadar to Splunk, crafting a scalable and resilient platform specifically for PCI compliance.
Diverse data sources were integrated, spanning cloud, endpoint, identity, and network environments. Use cases, correlation searches, and dashboards were developed to enable comprehensive monitoring of PCI-related activities.
Platform management
Engineering ownership was established to ensure the platform's uptime, performance, and scalability. Continuous monitoring of ingestion pipelines allowed for real-time detection of anomalies, latency, and data loss. Routine upgrades, health checks, and optimisation of query performance and storage tiers were performed.
Robust governance was embedded through Role-Based Access Control (RBAC) controls, audit trails, and documented operational runbooks. Ongoing KPI tracking, reporting, and alignment with the PCI-DSS framework were also provided.
Optimising for continuous compliance
A proactive improvement cycle was kept via quarterly service reviews and roadmap alignment
Automation was integrated to enhance reliability and enable swift remediation. A proactive improvement cycle was maintained through quarterly service reviews and roadmap alignment.
Collaboration with the client’s compliance and Security Operations Center (SOC) teams helped refine detections, analytics, and operational insights.
Notable outcomes
The integration of deep Splunk expertise within a managed service model allowed this oil and gas leader to confidently achieve PCI compliance with enhanced efficiency and visibility. Key outcomes included sustained PCI compliance with continuous monitoring and reporting, ensuring complete regional compliance visibility. The platform experienced zero unplanned downtime thanks to stability and proactive maintenance, keeping critical systems functional.
Expert supervision by certified engineers alleviated the internal teams' workload, enabling them to concentrate on developing insights and detection use cases. The consistent, validated data ingestion and accuracy of detections strengthened readiness for audits, instilling confidence in the compliance posture.
