The company describes a process-focused design that combines a physical-layer sensor, software analysis, and attack simulation; the available launch coverage and product page do not establish independent performance results.
What is SIGA SigaML²?
SigaML²—written as SigaML2 on SIGA’s current product page—is SIGA’s OT cybersecurity suite. SecurityWeek reported its launch on October 23, 2024, at the ICS Cybersecurity Conference in Atlanta. SIGA presents it as a multi-level approach spanning Levels 0–4, with components for visibility into physical processes, process-anomaly analysis, and simulation-based readiness.
The distinction matters: the product is positioned not simply as a network-monitoring tool, but as decision support that uses process-related information alongside other data. The descriptions below reflect SIGA’s product claims and SecurityWeek’s launch report, not independent validation.
How do SigaGuard and SigaGuardX differ?
| Component | Role described by SIGA | Deployment or function described |
|---|---|---|
| SigaGuard | Physical-process visibility at Level 0 | Hardware sensor installed on selected electrical I/Os; passively gathers raw signal data. |
| SigaGuardX | Process-oriented cybersecurity guardian for Levels 1–4 | SaaS offering that SIGA says provides real-time process-anomaly detection and decision support. SecurityWeek describes its analysis as AI/ML-based and drawing on data from various sources to surface information about potential OT breaches. |
| S-PAS | Attack-scenario simulation and training | SaaS add-on for real-time attack simulation and team readiness, according to SIGA. |
The labels describe SIGA’s product architecture; they do not demonstrate that every facility, control system, or electrical configuration is supported. The reviewed descriptions do not specify compatible hardware, installation prerequisites, integrations, or operational impact.

How does SIGA detect OT attacks at Level 0?
SIGA says SigaGuard is installed on selected electrical inputs and outputs and passively collects raw signals from the physical process. That is the basis of the company’s Level 0 visibility claim: the sensor is intended to observe process signals rather than relying only on conventional network telemetry.
For Levels 1–4, SIGA describes SigaGuardX as a SaaS process guardian that analyzes process anomalies and supports decisions in real time. SecurityWeek’s launch account says the analysis uses AI/ML and data from various sources. Neither source provides technical detail on the algorithms, alert thresholds, sensor coverage, false-positive rates, response automation, or independent test results. “Detection” should therefore be understood as the vendor’s stated capability, not a reported benchmark.
Does SIGA include OT incident-response training?
Yes. SIGA includes incident-response decision support in the suite’s positioning, and S-PAS is described as its attack-scenario simulation and training tool. SIGA calls S-PAS a SaaS add-on intended to help teams rehearse attacks and improve readiness. The sources do not detail scenario libraries, exercise design, supported environments, or how training outcomes are measured.
SIGA CEO Amir Samoiloff described the offering to SecurityWeek as an “OT Decision Support System (OT_DSS)” for managing cyberattacks with an embedded attack simulator. This is the company’s characterization of the product, rather than an independent assessment of its response effectiveness.

Which industries does SIGA target?
SIGA lists energy, oil and gas, defense and homeland security, water and wastewater, data centers and building management systems, and manufacturing as target sectors. This list identifies intended markets; it does not establish deployment at any particular organization or suitability for every facility in those sectors.
What does SIGA say about compliance reporting?
SIGA says its platform can help generate process data and event confirmation for NERC, NIS2, and CIRCIA reporting. That is a vendor claim about potential reporting support. The available sources do not establish that using the product results in compliance, satisfies a specific legal obligation, or provides legally sufficient evidence. Organizations should assess applicable requirements with their compliance and legal teams.

What should an OT team verify before evaluating the suite?
The launch report and current product page do not state pricing, detailed deployment prerequisites, supported electrical configurations, integration options, service-level terms, or independent comparative efficacy results. A technical evaluation should establish these points for the specific site rather than infer them from the product’s level labels or broad sector list.
