Discover the top managed detection and response (MDR) companies for energy and critical infrastructure sectors, and learn how to defend power grids, refineries and pipelines from cyber threats.
The energy industry powers modern life, from electricity grids and oil refineries to gas pipelines. Yet these systems are increasingly digitized and interconnected, making them prime targets for criminal gangs and nation‑state adversaries.
A 2025 overview from ClearNetwork notes that attacks on energy systems can threaten public safety, disrupt essential services and even weaken national security.
To guard against ransomware, insider threats and supply‑chain exploits, many energy companies turn to managed detection and response (MDR) providers with expertise in operational technology (OT) and industrial control systems.

Why the Energy Sector Needs MDR
Critical infrastructure operators face a unique mix of threats:
- Ransomware attacks: Criminals target utilities with ransomware to extort high payouts, knowing downtime is extremely costly.
- State‑sponsored intrusions: Nation‑state actors probe power grids and pipelines to gain strategic advantages or destabilize rivals.
- Insider threats and supply‑chain compromises: Employees, contractors or third‑party vendors may unintentionally or deliberately expose systems.
- Advanced persistent threats (APTs): Long‑term intrusions remain undetected while gathering intelligence or setting the stage for sabotage.
Given these risks, continuous monitoring and rapid response are essential. MDR services provide 24/7 visibility, threat hunting and incident remediation across IT and OT environments, enabling utilities to stay ahead of attackers.

| Fortra (Alert Logic) | Delivers proactive threat hunting, automated responses and rapid detection; includes real‑time dashboards and SOC experts. | Useful for utilities that need automated remediation and visibility across IT and OT networks. |
| Arctic Wolf | Concierge Delivery Model provides 24/7 threat monitoring, root cause analysis and guided remediation. | Ideal for energy organizations seeking personalized service and incident root-cause analysis. |
Best Practices for Securing Critical Infrastructure
Defending the energy sector requires layered defenses across technology, processes and people. Key practices include:
- Network segmentation: Separate IT and OT environments to prevent lateral movement and isolate critical systems.
- Managed firewall/IPS: Deploy intrusion prevention and deep packet inspection to block malicious traffic, especially on legacy systems that cannot be patched regularly.
- Continuous monitoring: Use SIEM and MDR tools to detect unusual traffic or unauthorized access in real time.
- Regular vulnerability assessments: Test both IT and OT systems to identify weaknesses and apply compensating controls.
- Incident response planning: Develop and rehearse response protocols, including communication with regulators and customers.
- Compliance frameworks: Align with standards like NERC CIP to maintain security baselines and foster accountability.
Choosing an MDR Provider for Energy
When selecting an MDR partner, consider:
- OT expertise: Does the provider monitor industrial control systems and understand protocols like DNP3 or Modbus? Forescout excels at OT visibility.
- Threat intelligence & context: Look for AI‑driven analysis and context‑aware prioritization. Netenrich’s SecLM integration provides this capability.
- Response speed & automation: Evaluate mean time to detect and respond. Providers like Fortra and Rapid7 emphasize automated responses and real‑time detection.
- Regulatory alignment: Ensure the MDR partner can support compliance with NERC CIP, ISO/IEC 27001 and other standards.
Conclusion
Energy and utility providers face high‑stakes threats that demand specialized defenses. MDR services tailored for critical infrastructure offer continuous monitoring, AI‑driven analytics and expert response across IT and OT systems.
By partnering with vendors such as Netenrich, Forescout, eSentire, Rapid7, Sophos, Fortra and Arctic Wolf, energy companies can strengthen resilience and maintain the availability of power, oil and gas services that underpin modern society.
