Critical Infrastructure & Utilities

Your operational network has run for decades.
Your internal trust has never been governed.

Critical infrastructure operators – electric utilities, water systems, oil and gas pipelines, transmission operators – run some of the most consequential networks in existence. Networks that were built for reliability and control, not security. Networks where OT and IT have converged over years of incremental connectivity, leaving behind a sprawling internal environment where SCADA systems, ICS platforms, PLCs, and enterprise IT communicate constantly – and almost none of those relationships are continuously validated. The consequences of getting this wrong aren’t measured in data loss. They’re measured in outages, public safety incidents, and national security implications. Enigma AI changes that. Agentless. Non-disruptive. Built for the operational realities of critical infrastructure networks.

The risk hidden inside critical infrastructure networks

Critical infrastructure is the most targeted sector by nation-state actors and sophisticated threat groups. The goal isn’t data theft – it’s disruption. And the path to disruption runs directly through the ungoverned internal trust relationships between OT and IT systems that have accumulated over decades of network evolution. In our pilots, critical infrastructure operators consistently discover:

  • SCADA and ICS systems communicating with enterprise IT in ways that were never formally authorized or reviewed
  • Engineering workstations with trust relationships to live operational systems that far exceed what their function requires
  • Remote access paths – vendor connections, jump hosts, maintenance windows – that were opened years ago and never properly closed
  • Legacy control systems and field devices with broad internal network access across flat OT segments
  • IT/OT boundary crossings that bypass intended segmentation and expose operational systems to lateral movement from the corporate network

A successful cyberattack on a critical infrastructure operator doesn’t just cost money – it can trigger cascading failures across interconnected systems, regulatory investigations, and federal incident reporting obligations. The 2021 Oldsmar water treatment attack and Colonial Pipeline incident demonstrated that even partial compromise of operational systems creates consequences that take weeks to contain. Governing internal trust is the control layer that closes the lateral movement paths those attacks exploited.

Internal Trust Governance for critical infrastructure networks

Enigma AI deploys passively using lightweight network sensors – no agents, no changes to OT device configurations, no impact on operational continuity. It works across the environments where critical infrastructure security problems actually live, including legacy protocols and architectures that conventional security tools were never designed to handle.

  • Discover every asset across IT, OT, and ICS environments – including legacy field devices and control systems that other tools cannot inventory
  • Map communication relationships between operational and enterprise systems and identify trust paths inconsistent with system intent
  • Generate segmentation policy based on how systems actually communicate – the foundation for IT/OT boundary enforcement that holds up under operational scrutiny
  • Monitor continuously for trust drift as vendor connections, remote access paths, and system configurations change

Enigma AI works across electric utilities, water and wastewater operators, oil and gas pipeline operators, transmission system operators, and critical manufacturing environments navigating the convergence of decades-old OT infrastructure with modern enterprise IT.

Compliance & regulatory alignment

Critical infrastructure operators face some of the most prescriptive and rapidly evolving regulatory requirements of any industry – and regulators are becoming explicitly more specific about internal network governance. Enigma AI supports audit readiness across the frameworks that matter most:

NERC CIP (Critical Infrastructure Protection)

mandatory reliability standards for bulk electric system operators with specific requirements for electronic security perimeters, system access controls, and configuration monitoring that internal trust governance directly supports

CISA guidance and ICS-CERT advisories

federal guidance consistently emphasizes network segmentation, east-west traffic visibility, and internal communication monitoring as foundational controls for critical infrastructure operators

NIS2 Directive

EU requirements for operators of essential services mandate risk management measures, incident reporting, and internal network security controls for organizations operating in European markets

TSA Security Directives

pipeline and surface transportation operators face mandatory cybersecurity requirements including network segmentation and access control measures introduced following recent high-profile incidents

NIST SP 800-82

the definitive guide to industrial control system security, widely referenced by regulators and used as the baseline framework for OT security programs across critical infrastructure sectors

Enigma AI helps organizations meet these expectations by providing continuous visibility into OT and IT network communications and enabling segmentation strategies aligned with federal and international frameworks.

See your internal trust surface in 30 days

Most critical infrastructure security teams have never seen a complete map of system-to-system trust relationships across their OT and IT environments. Our 30-day pilot delivers exactly that — a full Internal Risk Index across your operational and enterprise network, with no agents and no disruption to operational continuity.
