Process-oriented OT Cybersecurity for Critical Infrastructure
Multi-Level OT Cybersecurity
REQUEST SOLUTION DEMOMulti-Level Machine Learning For OT Resilience
Uninterrupted processes are the core of every critical operation.
SigaML² provides early alerts and real-time decision support during the "expression phase" of an attack, when traditional tools are often blinded.
The Core of the Solution
Automated Process Baselining
SigaML² continuously learns the normal behavior of critical OT processes to automatically detect malicious process manipulations designed to cause shutdowns or physical damage.
Cross-Level Data Comparison
By comparing raw Level 0 electrical signals with reporting data from Levels 1–4, the platform instantly catches discrepancies.
Our comprehensive, multi-level OT cybersecurity suite, comprising three standalone cybersecurity solutions:
The physical foundation. An out-of-band hardware sensor that captures raw electrical signals to establish uncompromised "Physical Truth".
The analytical engine. Advanced software that correlates Level 0-4 data to identify False Data Injection and stealth attacks in real-time.
A simulator that safely injects software-based anomalies to train teams on real attack patterns without risking live equipment.
Key Benefits
Early Threat Detection
Detects physical impact during the exploitation phase, before processes are compromised.
High-Certainty Insights
Distinguishes genuine cyber incidents from operational faults using physical validation.
Regulatory Compliance
Provides the forensic evidence needed for NERC, NIS2, and CIRCIA reporting.
Zero Operational Risk
Fully non-intrusive, out-of-band architecture with no impact on live equipment.
Incident Response Lifecycle (NIST Framework)
- Readiness: Train teams using Siga-PAS to simulate realistic attack scenarios and build shared operational playbooks without affecting live equipment.
- Safety: Identify security gaps through full-scale simulations in a controlled, software-only environment.
- Visibility: SigaGuard captures the "physical truth" at Level 0, detecting the earliest expressions of an attack via raw electrical signals.
- Verification: SigaGuardX uses ML to immediately expose False Data Injection by comparing reported HMI data against physical behavior.
- Decisive Action: Provides the real-time assessment needed to safely decide whether to shut down, disconnect, or continue operations.
- Intelligence: Identifies the exact attack vector and spread, enabling surgical eradication of the threat.
- Validation: Use unfiltered Level 0 data to verify the process has safely returned to a stable state.
- Evidence: Maintain forensics-ready records with high-resolution sampling (10–100 Hz) to reconstruct how and where an attack occurred.
Core Standards Support
For organizations facing increasing regulatory pressure, the SigaML² suite provides a verifiable physical evidence base to support global governance requirements. By monitoring the "physical truth" at Level 0, SIGA helps asset owners bridge the gap between technical reality and mandatory reporting mandates.
Regulatory Compliance & Global Standards Alignment
NIS2 Directive (EU)
Delivers continuous process integrity evidence required for European regulatory reporting and internal assurance. SigaGuardX provides high-resolution forensic records to meet strict 24-72 hour incident notification clocks.
NERC CIP
Supports grid reliability and mandatory field I/O monitoring for critical power infrastructure. It provides real-time validation to detect incorrect data in SCADA systems, aligning with current reliability standards.
U.S. CIRCIA / TSA
Enables mandatory impact verification and reporting compliance through validated Level 0 data. This ensures that even "blinded" SCADA systems do not prevent accurate forensic reconstruction of a cyber event for federal reporting.
