OT Digital Twin Security

Simulate Before You Execute. Every Time.

Simara builds physics-accurate digital twins of industrial facilities on NVIDIA Omniverse with PhysX. Before Quellra Edge isolates a PLC, Simara answers the question every OT security team needs: what breaks downstream?

Core Capabilities

Consequence-Aware OT Security

No OT security vendor — not Claroty, Dragos, or Nozomi — offers physics-based digital twin simulation. Simara creates a new category: security that understands what the attack will do to the physical world before you act on it.

Omniverse Digital Twin

Import facility CAD models from Siemens NX, Autodesk, or SolidWorks into NVIDIA Omniverse. Map every PLC, RTU, HMI, sensor, and actuator to a 3D twin object. Real-time telemetry sync from Quellra Edge keeps the twin state current.

PhysX Consequence Engine

NVIDIA PhysX accelerates fluid dynamics, thermal modeling, and electrical load simulation 100x faster than CPU rendering. GPU physics shaders trace cascading failure chains across 10,000+ interconnected devices in real time.

Attack Consequence Simulation

Inject simulated attacks into the digital twin: PLC logic tampering, sensor spoofing, HMI command injection, protocol fuzzing. The consequence engine propagates impact across the facility and visualizes the failure chain in 3D.

Containment Policy Testing

Test every proposed Quellra Edge containment action in simulation before deploying it to live equipment. Each action receives a safe/unsafe classification and an optimal mitigation sequence — with estimated production impact.

ICS Protocol Modeling

Deep protocol simulation covers Modbus TCP/RTU, DNP3, OPC-UA, Profinet, EtherNet/IP, IEC 61850, and BACnet. Protocol-aware attack injection generates the exact function-code manipulation an adversary would use on live equipment.

Synthetic Training Data

Generate ICS protocol attack sequences — Modbus function code manipulation, DNP3 command spoofing, OPC-UA read/write attacks — for Quellra Edge model retraining. Fills gaps where real-world attack samples are scarce.

Technical Demo

Know the Consequences Before You Act

When Quellra Edge detects a threat to PLC-07, it sends the proposed containment action to Simara. Simara loads the facility digital twin, runs PhysX consequence propagation, and returns a safe/unsafe verdict with a recommended action sequence — all before a single command reaches live equipment.

  • Verdict delivery under 30 seconds for typical facility scale
  • Optimal mitigation sequence generated with step-by-step timing
  • Probability scoring: 87% cascading failure prediction accuracy
  • All simulation results logged as audit evidence for regulators

Quellra Ecosystem

The Physical Reality Layer for the Entire Platform

Every Quellra product feeds Simara. Quellra Edge streams live OT telemetry to keep twin state current. Vendex alerts flow in when compromised packages are detected in OT firmware. Core incidents trigger Simara consequence checks before containment executes. Simara's synthetic training data flows back out to sharpen Edge detection models for attack classes that have never happened in the wild.
