Manufacturing & Critical Infrastructure

Model the system before you touch the system.

Operational technology runs for decades, can't be taken down for a casual change, and increasingly connects to the IT systems around it. ThreatModeler^® Nexus™ lets you understand the design and its risk as a model, so you see where exposure lives without disturbing what's keeping the plant running.

Book a demo How it works

You can't pause the line to find out where the risk is.

The OT reality

Long-lived systems, converging with IT, that you can't simply rebuild.

Industrial environments were designed for uptime and safety, often before security was a first-class concern. As they connect to corporate networks, the trust boundaries shift, and the design was rarely written down anywhere current.

"These systems have been running for years. There's no current diagram, and no one wants to probe production to make one."

Build the model without disturbing operations. The System Mapping Agent infers the design from what's documented and deployed, and the Secure Design Graph grounds it in the real context, so you get a current model without testing against live equipment.

"As we connect OT to IT, the boundary between them keeps moving and we lose track of what trusts what."

See the trust boundaries. The model represents where operational and corporate systems meet, so the exposure created as they converge is visible in the design rather than discovered later.

"Scanning tools assume IT systems we can patch on demand. That's not how our plant floor works."

Find what's missing, design the fix. Because the model reasons about intended design, it surfaces the control that should protect a system you can't easily change, so you can plan mitigations around operational constraints.

Design-level understanding

Risk you can reason about, without touching production.

ThreatModeler Nexus is a threat modeling platform first: it shows what could go wrong in a system so you can mitigate it. For operational environments, that analysis happens in the model, away from the equipment that has to keep running.

Non-intrusive

Model, don't probe

Understand the design from artifacts and inferred structure, so analysis happens in the model instead of against live operational systems.

Boundary-aware

Where IT meets OT

The model represents the trust boundaries between corporate and operational systems, so convergence risk is visible by design.

Governed

Consistent and current

Versioning and a full audit trail keep the picture defensible, and a deterministic framework keeps the AI on your approved content.

Regulatory and framework coverage

Mapped to the standards your industrial systems must meet.

OT and critical infrastructure security operates under a distinct set of standards from IT, IEC 62443 defines security levels for industrial control systems; NIS2 extends essential-service obligations across Europe; NERC CIP covers bulk power systems; NIST 800-82 guides industrial control system security. ThreatModeler Nexus maps threat models to these frameworks automatically, so the controls your system implements are demonstrably tied to the standard that requires them.

Automotive programs under ISO/SAE 21434 and WP.29 TARA requirements are also supported: from the design phase through model updates across the vehicle lifecycle.

See the Graph Agent

✓

IEC 62443. The reference standard for industrial control system security. Controls mapped by Security Level (SL-1 through SL-4), with findings grounded in actual system architecture rather than assessments of present configurations.

✓

NIS2 Directive. Essential and important entity requirements for operational resilience, incident reporting, and supply chain security, mapped at the design level.

✓

NERC CIP. Bulk power system cybersecurity standards applied to the systems and assets in scope, with audit-ready evidence for each applicable requirement.

✓

ISO/SAE 21434 and WP.29 TARA. Automotive cybersecurity requirements from concept through production and field use, with threat analysis and risk assessment built into the design workflow.

✓

NIST CSF and 800-82. Critical infrastructure and ICS security frameworks, with cross-mapping to MITRE ATT&CK for ICS for attack-path analysis grounded in the model.

Industrial threat intelligence

Attack paths grounded in how industrial systems actually fail.

The Secure Design Graph includes curated threat libraries specific to industrial, embedded, and operational environments, not general IT threat lists applied to OT.

MITRE ATT&CK for ICS

Industrial attack paths

Threat findings align to MITRE ATT&CK for Industrial Control Systems: so attack scenarios map to how adversaries actually move through operational environments, not how they move through enterprise IT.

MITRE EMB3D

Embedded device threats

Threats for embedded and connected devices, mapped to IEC 62443 mitigations at three levels: Foundational, Intermediate, and Leading. Designed for devices that can't be patched on demand.
