Penetration Testing: Protecting an Energy Enterprise Against Chained Attack Paths
Find out how we mapped exploitable attack paths, validated defences and prioritised remediation for a large refining and fuel retail enterprise.
The Challenge
The organisation ran a converged environment spanning refinery operations, logistics, dealer networks & digital payments. Leadership needed proof of how attackers could chain weaknesses into real operational impact & an adversary-style view of those paths.
Our Approach
We implemented a risk-based annual penetration testing programme covering external applications, internal networks, cloud identity, forecourt payment systems and plant network boundaries.
Key Results
- Identified exploitable attack paths across external assets
- Reduced critical findings after retesting cycle
- Improved IT and plant network segmentation
- Faster remediation through risk-based finding prioritisation
- Strengthened forecourt and payment system resilience
Service Highlights
- Established a risk-based scope covering external applications, corporate networks, cloud tenants and plant boundaries.
- Tracked exposed assets, leaked credentials and misconfigured cloud services through reconnaissance before exploitation.
- Simulated credential theft, session abuse and privilege escalation against enterprise and dealer-facing portals.
- Enabled testing of forecourt controllers, payment terminals and fleet loyalty applications with strict safeguards.
- Validated every finding manually to remove false positives and confirm real exploitability.
- Delivered live alerts to security teams when critical issues emerged during testing.
- Provided executive and technical reports with attack narratives and remediation priorities.
Client Gains
- Greater confidence in operational continuity
- Stronger board-level visibility of cyber risk
- Clearer evidence for regulatory audit reviews
- Safer dealer and vendor connectivity
- Repeatable security assurance year on year
Client Testimonial
“I now see how separate weaknesses combine into real attack paths, and my teams know what to fix first. Every annual cycle gives us dependable evidence of progress that leadership and regulators can trust.”
