What SIGA OT Solutions does
SIGA OT Solutions (legal entity SIGA Data Security LTD.) is an Israel-based cybersecurity company founded in 2014 that provides process-oriented OT security for critical infrastructure operators. Its core proposition is monitoring raw electrical signals at Level 0 of the Purdue Model — the physical process layer beneath PLCs, HMIs, and SCADA networks — using an out-of-band hardware sensor (SigaGuard) to establish an uncompromised source of truth that remains trustworthy even when the upper layers of the control network are compromised. The accompanying SigaGuardX analytics software correlates this Level 0 data against Levels 1-4 reporting streams via "Parallel Reference Monitoring" to detect False Data Injection and other stealth cyber-physical attacks (Stuxnet-class) in under one second, while SigaPAS provides attack simulation and training. The platform is built on an unsupervised machine learning engine that establishes site-specific operational baselines without predefined system models.
The company sells to critical infrastructure operators across power & energy utilities, oil & gas, water & wastewater, data centers/BMS, manufacturing, and defense/HLS — with named customers including the New York Power Authority (validated at a 345kv substation), Israel Electric Corporation, IREN Group, Dalia Energy, Jordan Valley Water, Hagichon Water, and the Israeli National CERT. Revenue mechanics combine hardware sales (SigaGuard), annual software subscriptions with I/O token connector licensing (SigaGuardX), and professional services/training (SigaPAS). GTM is multi-channel: direct enterprise field sales, a three-tier global partner program (Certified, Business, Assembly) with distributors across Europe, North America, Asia, and Latin America, a Microsoft Azure Marketplace listing for cloud/hybrid procurement, and active conference presence at OT-cyber events. The company has raised approximately $11.6M in disclosed funding (Series A 2017, Series B 2021), is led by co-founders Amir Samoiloff (CEO) and Ilan Gendelman (CTO), and operates with a European subsidiary in Luxembourg to serve EU and global markets.

SIGA OT Solutions product offering
Product offeringCore offering
SIGA provides an OT anomaly detection solution by real-time monitoring the raw electric signals of critical industrial assets through its SigaML² suite. The offering combines Level 0 hardware sensors (SigaGuard) that passively capture electrical I/O signals with multi-level analytics software (SigaGuardX) and a process attack simulator (SigaPAS) for training, targeting critical infrastructure operators in power, oil & gas, water, data centers, manufacturing, and defense.
Product overview
SIGA OT Solutions offers a process-oriented OT cybersecurity platform called SigaML2, which comprises three integrated products: SigaGuard (Level 0 hardware sensor capturing raw electrical signals from the physical layer), SigaGuardX (multi-level analytics software correlating Purdue Model Levels 0-4 data to detect False Data Injection and stealth attacks), and SigaPAS (Process Attack Simulator for team training and readiness). The platform is designed for critical infrastructure operators to detect cyber-physical manipulation during the expression phase of an attack, providing incident response decision support when traditional tools are blinded.

Products and services
- SigaML² SigaML² is the overarching OT cybersecurity suite that combines hardware and software to provide process-oriented cyber resilience. It applies Machine Learning across ICS Levels 0-4 and supports the full lifecycle of the NIST SP 800-82 Incident Response Framework, serving critical infrastructure operators.
- SigaGuard SigaGuard is a Level 0 hardware sensor that captures raw electrical signals directly from sensors and actuators. It provides an out-of-band, uncompromised source of physical truth independent of PLCs, HMIs, or networks, enabling earliest detection of cyber-physical manipulation for critical infrastructure operators.
- SigaGuardX SigaGuardX is an advanced multi-level analytics software that correlates data from Purdue Model Levels 0-4 to identify False Data Injection and stealth attacks in real-time. It validates reporting data against Level 0 physical truth to distinguish genuine cyber incidents from operational faults for critical infrastructure operators.
- SigaPAS SigaPAS (Process Attack Simulator) is a SaaS training and simulation tool that safely injects software-based anomalies to prepare teams for real-world cyber incidents. It provides realistic attack scenario training without risk to live equipment and includes tabletop training capabilities for end-to-end exercises, targeting OT security and operations teams at critical infrastructure operators.

SIGA OT Solutions competitors and assessment
Company assessmentDirect peers
- Nozomi Networks: OT and IoT security vendor with strong presence in power utilities, oil & gas, and manufacturing. Direct competitor using network-based anomaly detection and asset visibility approaches, in contrast to SIGA's Level 0 electrical signal monitoring, but competing for the same enterprise budget.
- Claroty: Leading OT/ICS cybersecurity platform serving critical infrastructure operators with network-based monitoring, asset discovery, and vulnerability management. Direct competitor for the same critical infrastructure CISO budget that SIGA targets, with a much broader platform and larger installed base.
- Dragos: Industrial cybersecurity vendor specializing in ICS/SCADA environments with focus on power, water, and oil & gas. Direct competitor targeting similar critical infrastructure operators with comparable enterprise sales motion, incident response offerings, and threat intelligence positioning.
- Radiflow: Israeli OT cybersecurity vendor focused on critical infrastructure network monitoring and industrial threat detection. Direct peer also serving Israeli and European utilities and industrial sites, and notably a current SIGA channel partner — both compete and collaborate.
- SCADAfence: OT/ICS security platform now part of Honeywell following its 2024 acquisition. Direct competitor in OT network monitoring for critical infrastructure, with comparable enterprise sales motion and customer profiles; now backed by Honeywell's industrial automation scale.
Broad incumbents
- Honeywell Forge Cybersecurity: Industrial conglomerate's cybersecurity portfolio (now including acquired SCADAfence) offering broad OT security across process industries. Broad incumbent with deep installed base in industrial automation and direct customer relationships that overlap SIGA's target buyers.
- Forescout: Network security vendor with significant OT/IoT security capabilities via its eyeSegment and SilentDefense platforms. Broad incumbent competing in OT security buying cycles with broader network visibility and asset management positioning rather than Level 0 signal monitoring.
- Tenable OT Security: Tenable's OT security offering (via the Indegy acquisition) provides asset discovery, vulnerability management, and threat detection for industrial environments. Broad incumbent offering adjacent capabilities to SIGA's process-level monitoring from a much larger IT/OT security platform.
Emerging players
- OTORIO: Israeli OT security startup now part of Hitachi Energy, providing OT security posture management for industrial environments. Emerging peer with overlapping Israeli innovation ecosystem roots and critical infrastructure focus, but a different technical approach (risk management vs. Level 0 signal monitoring).
- Mission Secure: OT cybersecurity company focused on industrial control system protection with services-led and platform approach. Smaller competitor serving overlapping critical infrastructure customers with a broader cybersecurity services portfolio and plant-floor presence.
