Use case
Real-Time Process Integrity Monitoring
Industry: Power Plants (Thermal & Nuclear)
Ensuring Real-Time Process Integrity in Thermal & Nuclear Power Plants
Modern power generation depends on deterministic control systems -PLCs, DCS, SCADA, HMIs, field RTUs and an increasing number of IIoT sensors -working reliably across complex industrial networks. For thermal and nuclear plants, where process deviations can create catastrophic safety, environmental or financial consequences, continuous assurance of process integrity is not optional. Shieldworkz delivers an enterprise-grade, OT-native Real-Time Process Integrity Monitoring solution designed specifically for the unique risk profile of Power Plants (Thermal & Nuclear).
Industry challenges
Power generation environments face converging pressures:
Legacy control equipment (older PLC/DCS firmware, proprietary protocols) connected to modern networks for efficiency and remote monitoring.
Increased IIoT telemetry and vendor remote access expanding the attack surface.
Strict regulatory/compliance regimes and zero-tolerance for unplanned outages or safety incidents.
Complex interdependencies between safety-instrumented systems (SIS), protection relays and control loops where even small command anomalies can escalate.
Limited OT staff availability and the need for non-disruptive monitoring that preserves deterministic control traffic
The OT/IIoT Risk Landscape: Threats to Instrumentation
Thermal and nuclear plants are targeted by both opportunistic and highly resourced actors. Common threat vectors include:
Protocol abuse and command injection (Modbus, DNP3, IEC 61850, OPC-UA) to alter setpoints or actuator states.
Sensor/telemetry spoofing and replay attacks causing control loops to operate on false data.
Lateral movement from IT to OT via vendor access, maintenance laptops or misconfigured jump hosts.
Unauthorized configuration or logic changes to PLC/DCS programs and firmware tampering.
Insider or third-party misuse of privileged HMI/engineering workstations. These threats undermine the integrity of process measurements and control actions -the core risk that our monitoring addresses
Regulatory & compliance considerations
Power Plants must align to a mix of safety and cybersecurity mandates (e.g., NERC CIP variants for generation, IEC 62443 lifecycle requirements, national nuclear regulatory cybersecurity guidance). Auditors require demonstrable detection, logging, change control and incident response capabilities for control-system integrity. Shieldworkz helps operationalize compliance through continuous evidence collection, tamper-proof logs and role-based controls mapped to regulatory controls.
How Shieldworkz solves these challenges
Shieldworkz combines OT-native monitoring, deterministic baselining and industrial-physics awareness to protect process integrity in real time
Protocol-aware deep inspection for Modbus, DNP3, IEC 61850, IEC 60870-5-104, OPC-UA and vendor-proprietary protocols -enabling semantic detection of malicious or out-of-policy commands
Agentless asset discovery & deterministic baselining that produces a trusted inventory of PLCs, RTUs, HMI sessions and IIoT endpoints with behavioral baselines tied to normal control sequences.
Process model correlation -cross-validates control commands against expected physical responses and multi-sensor redundancies to detect spoofing and sensor drift without touching the control logic
Real-time anomaly scoring & prioritized alerts aligned to safety impact (e.g., potential for trip, thermal excursion, radiological release risk in nuclear contexts) so OT teams focus on what matters.
Forensic logging & immutable audit trails suitable for incident response and regulatory review, including signed event chains and session recordings
Integrated OT MDR & IR services -Shieldworkz provides 24/7 monitoring, threat hunting, runbook-led incident response and ICS forensics performed by certified OT analysts.
Platform capabilities & professional services
Shieldworkz offers a complete delivery stack:
Platform: passive taps & inline sensors, protocol DPI, deterministic baselining engine, process modeling, alert orchestration, compliance reporting and APIs for SIEM/SOAR.
