From limited visibility to full control.

Oil & gas leader achieves real-time IT/OT visibility and resilience.

// Client overview

A premier oil and gas organization operating in India, spanning exploration, drilling, extraction, refining and distribution across upstream, midstream and downstream activities. The organization operates more than 32 data centers across India, connected through a wide area network (WAN), along with several standalone facilities supporting critical field operations.

Business functions rely extensively on IT systems. In the oil and gas sector, exploration is driven by geological, geophysical and other data across Acquisition, Processing and Interpretation phases, supported by specialized IT platforms; reserve estimation and reservoir studies depend on advanced systems for complex data analysis, and SCADA systems monitor and manage production for real-time oversight and operational control. As the organization expanded its digital infrastructure across multiple operational sites and data centers, it faced increasing challenges in managing security across distributed environments.

// Key challenges

Limited visibility across IT and OT environments - most critically at remote operational sites.

Lack of centralized monitoring and correlation of security events across the distributed systems.

Absence of a comprehensive asset inventory, making it difficult to monitor field-level devices and industrial control systems.

Trouble rapidly detecting, isolating and responding to cyber threats targeting critical infrastructure.

Without integrated monitoring across enterprise IT and industrial environments, assessing overall security posture and quickly detecting, isolating, preventing and remediating attacks became increasingly difficult.

Converged IT and OT networks with limited segmentation, increasing exposure to lateral cyber threats.

Unsecured OT network zones and weak access-control mechanisms.

Presence of unauthorized software on OT-connected systems.

Use of workgroup-based systems without centralized security enforcement.

Limited staff awareness of OT cybersecurity policies and operational security practices, with no structured OT cybersecurity training programs.

Inadequately reviewed and documented OT network security policies.

Increased operational risk from potential cyberattacks capable of manipulating industrial systems and algorithms, with safety concerns where certain attacks could trigger physical damage or life-threatening incidents.

// The solution · highlights

Evaluated cyber risks across both IT and operational environments, then designed an end-to-end cybersecurity monitoring framework with advanced analytics and intelligent threat detection to enhance visibility, strengthen detection and improve cyber resilience.

Established an on-premise 24×7 Information Security Operations Center (ISOC) for continuous monitoring and management of security incidents and vulnerabilities - providing broader org-wide security support, early incident detection, defense of websites, applications, databases, data centers, servers, networks, endpoints and desktops, reduced regulatory/compliance risk, and comprehensive reporting and analytics.

Phase 1 - IT Infrastructure Security Integration: integrated and monitored servers, endpoints, network devices and security appliances into a next-gen SIEM and Big Data analytics platform, with DAM, Packet Capture (PCAP), SOAR and IT-GRC. Completed and in operation.

Phase 2 - OT Security Visibility: extended visibility into OT with Deep Packet Inspection (DPI) for the ICS environment, integrated with the enterprise analytics platform; a POC was run with Nozomi Networks and is under discussion following successful validation.

Deployed SCADA-qualified cybersecurity engineers trained to IEC 62443 inside the SOC, delivering log correlation and actionable alerts, real-time detection and reporting of critical incidents, forensic investigation and root-cause analysis, and on-demand external/internal penetration testing.

Ran continuous vulnerability assessments across networks, servers, databases and applications, with remediation strategies, continuous risk assessment across distributed data centers, and threat intelligence drawn from OEM, cloud and government sources.

Aligned network segregation and layered controls with the Purdue Enterprise Reference Architecture.

// Outcome & benefits

Real-time operational visibility across IT and OT environments.

Enhanced cybersecurity posture for critical infrastructure.

Rapid detection and mitigation of threats targeting industrial control systems.

Improved protection of process reliability and operational safety.

Creation of a global, automated asset inventory with detailed device intelligence.

Better threat intelligence and proactive risk mitigation.

Strengthened compliance and reporting capabilities.

// By the numbers · ROI

Automation lowered the cost per incident handled and deferred hiring of additional L1 analysts.

Time saved meant more value-added work, reduced burnout and improved job satisfaction.

Avoidance of major incident costs - potentially USD 100,000 to USD 1 million per breach - through proactive detection and response.
