Multi-Level OT Cybersecurity with Process Intelligence

Advanced Multi-Level analytics for cyberattack detection and investigation across OT operations based on trusted process-level insight.

REQUEST SOLUTION DEMO

SigaGuardX is a software solution that instantly alerts on cyberattacks that exploit the physical layer to force process shutdowns or damage critical machinery - with or without Level 0 hardware.

The platform utilizes Machine Learning to learn the normal behavior of the process by collecting its full process data from Levels 1-4 and detecting subsequent anomalies.

When combined with SigaGuard hardware, it elevates this defense by validating that Level 1-4 data against an unalterable, out-of-band physical reference.

Key Benefits

Detection of False Data Injection (FDI)

Detection of False Data Injection (FDI)

SigaGuardX excels at identifying "stealth" attacks (similar to Stuxnet) where an attacker manipulates the process while sending false "normal" data to operators.

High-Certainty Insights

High-Certainty Insights

By scoring and prioritizing alerts based on cross-level evidence, it distinguishes genuine cyber incidents from simple operational faults.

Full Stack Visibility

Full Stack Visibility

Provides a single operational view that verifies activity across Levels 0–4, ensuring there are no blind spots in the ICS environment.

SigaGuardX at a Glance

SigaGuardX Dashboard Installation Map Cyber Event Summary

The SigaGuardX Dashboard provides a centralized operational view. It displays the 'Levels Data' graph, which visually overlays Level 0, HMI, and OPC data to highlight discrepancies, alongside a 'Parallel Reference Monitoring' status to ensure all I/O pairs are being accurately validated.

Key differentiators

The only Process-Level OT Cybersecurity solution in the market.

Direct visibility into the physical layer to support safety, reliability, and operational continuity.

CHALLENGE
Undetected Control Network Intrusion
Persistent Alert Fatigue
Falsified Software Telemetry and Logs
Spoofed HMI Screens
DIFFERENTIATOR
Traditional network monitoring tools only analyze data traffic. SigaGuardX software unifies your security architecture by continuously aggregating and correlating digital reporting states across Purdue Levels 1–4 with the unalterable, out-of-band physical reality captured by SigaGuard hardware at Level 0.
Cyber alerts typically lack physical context. SigaGuardX software utilizes unsupervised machine learning to track process baselines and prioritize alerts. By correlating cross-level evidence, it automatically separates serious cyber incidents from simple operational faults
Standard software tools and event logs can be blinded or manipulated during a breach. SigaGuardX software continuously cross-references digital reporting layers with a separate, isolated stream of raw Level 0 physical signals captured via out-of-band SigaGuard hardware.
Hacked control systems can display false, "normal" data to operators during an attack. SigaGuardX software visually overlays SCADA and HMI data with raw physical signals from SigaGuard hardware to instantly expose discrepancies and hidden process manipulation.
OUTCOME
Full Stack Visibility 
Operational Fault detection
Process Trustworthiness
Detection of FalsE Data Injection (FDI)
CHALLENGE
PROCESS-LEVEL DETECTION
DIFFERENTIATOR
Network monitoring tools only analyze data traffic. SIGA captures raw electrical signals directly at the process level to prevent downtime during the early expression phase.
OUTCOME
DOWNTIME PREVENTION
CHALLENGE
CYBER AND OPERATIONAL INSIGHTS
DIFFERENTIATOR
Cyber alerts typically lack physical context. SIGA provides independent process verification, enabling Incident Response teams to maintain stable, continuous operations safely.
OUTCOME
OPERATIONAL CONTINUITY
CHALLENGE
UN-HACKABLE DATA INTEGRITY
DIFFERENTIATOR
Standard security tools can be blinded during a breach. SIGA operates completely out-of-band, isolating monitoring from vulnerable networks to deliver trusted data during a crisis.
OUTCOME
TRUE RESILIENCE
CHALLENGE
FDI PREVENTION
DIFFERENTIATOR
Hacked control systems can display false HMI readings. SIGA cross-references SCADA software data with raw physics to instantly expose false data injection attacks.
OUTCOME
RELIABILITY & TRUST

Frequently Asked Questions

How does SigaGuardX detect attacks that upper-layer tools miss?
A core component of SigaGuardX is Parallel Reference Monitoring. It continuously compares reporting data from Levels 1-4 (PLCs, HMIs, historians) with the trusted, unfiltered Level 0 data captured by SigaGuard hardware. This allows it to immediately identify discrepancies caused by False Data Injection - where an attacker manipulates the process while sending "normal" values to the operators.
Can SigaGuardX work without installing SigaGuard hardware?
Yes. SigaGuardX software can be applied to Level 1–4 data alone. However, to achieve full Level 0 visibility and definitive protection against False Data Injection (Stuxnet-like) attacks, it must be connected to the SigaGuard physical sensors.
How does SigaGuardX integrate with my existing OT infrastructure?
It is a software solution that supports multiple connectors, enabling it to pull communication from PLCs using various protocols, as well as HMIs, SQL databases, OPC servers, and BI solutions.
What is the pricing model for SigaGuardX?
The base product is offered through an annual subscription. On top of the base subscription, customers purchase yearly licenses for "I/O token connectors" for each specific digital or physical data point connected to the system.
