Oil and Gas Cybersecurity
Protect your production, people, and reputation with integrated, OT-aware security
Top cybersecurity challenges facing oil and gas
For the oil and gas industry, a cyber breach is no longer limited to data loss. It can create operational disruption, safety exposure, environmental risk, and broader national energy security concerns. With ransomware activity against the sector rising sharply and industrial downtime carrying significant financial and operational impact, oil and gas leaders need a resilient cybersecurity strategy that protects both enterprise IT and mission-critical operational technology (OT).
Limited visibility across IT and OT environments
Security teams often lack a unified view of endpoints, networks, cloud, field assets, and industrial control systems.
Operational downtime risk
Ransomware or cyber incidents can disrupt wells, pipelines, refineries, terminals, and offshore operations.
Legacy OT systems and insecure protocols
Many industrial systems were not designed with modern cybersecurity controls, making them harder to monitor, patch, and protect.
Weak segmentation between IT and OT
Poor separation increases the risk of an IT-side compromise spreading into production environments.
Regulatory and compliance demands
Customers must meet stricter requirements around resilience, incident response, data protection, and critical infrastructure security.

Fortifying the full oil and gas value chain
Trellix helps secure and enforce compliance across the entire digital operating environment, from enterprise IT to critical OT systems supporting wells, pipelines, terminals, refineries, control rooms, and field operations. Our integrated cybersecurity spans endpoint, network, and data security, threat intelligence, consulting, and security operations. Backed by industry-validated solutions, strategic partnerships, and decades of expertise, we help protect both legacy and modern OT infrastructure, whether deployed in isolated OT environments or across converged IT/OT architectures.
Protecting critical oil and gas data
Across upstream, midstream, and downstream operations, Trellix Data Loss Prevention and Database Security help protect the sensitive data that powers the oil and gas business. This includes seismic data, well data, production records, pipeline telemetry, refinery data, engineering designs, trading information, commercial contracts, and regulated information.
Upstream: Securing the intelligent edge
Trellix helps protect remote exploration and production environments, from offshore platforms and field endpoints to engineering workstations, contractor access, wellhead sensor data, and cloud-connected analytics. With resilient endpoint protection, detection, and response capabilities, Trellix helps secure the data flows that support exploration, production, and decision-making in low-bandwidth and remote operating environments.
Midstream: Enforcing pipeline integrity
Trellix helps safeguard distributed pipeline, terminal, compression, and pumping station environments by improving visibility across SCADA-connected and OT-adjacent networks. Network detection and response, endpoint protection, and threat intelligence help identify suspicious activity, unauthorized access attempts, lateral movement, and threats targeting critical transportation and storage infrastructure.
Downstream: Driving safety-first refinery protection
In refineries, depot centers, and petrochemical plants, uptime, safety, and process continuity are paramount. Trellix integrates directly with industrial control systems (ICSes) to monitor for anomalies that signal sabotage or operational failure, aligning your cybersecurity with your health, safety, and environment (HSE) goals. Our Trellix Wise AI capabilities help understaffed SOC teams prioritize the alerts that matter most to production.
Partner for critical infrastructure resilience
OEM partners integrate embedded Trellix security controls such as endpoint access control, encrypted data transfer capabilities, and more to help ensure the safety of ICSes, maintain operational integrity, and enforce compliance with industry regulations.
