Defense and HLS operations depend on mission-critical facilities that form the backbone of national security and readiness.
Standard network security lacks the visibility to detect the physical progression of a cyberattack or guide the necessary response.
SIGA provides an uncompromised source of truth and step-by-step playbooks to verify the physical state of the site and accelerate incident recovery.
Legacy Challenge
Attack Scenarios
SIGA monitors raw electrical signals at Level 0 to provide an unfiltered view of the physical process.
By analyzing data directly from the source, it identifies malicious manipulation of PLC logic or sensor values – including false data injections – even when the HMI is spoofed.
01 |
Attack Vector
Malicious manipulation of port access control systems.
02 |
Consequence
Physical barriers are forced open while the security console falsely reports them locked.
03 |
impact
Severe breach of border control integrity, enabling unauthorized entry at maritime ports.
The solution suite provides the earliest alerts during the expression phase of an evolving OT cyber-attack.
It supports the entire Incident Response process by offering process attack simulation for team preparation, real-time threat detection and classification, and critical decision support for containment and recovery.
Multi-Level Operational Resilience for the Defense / HLS Sector
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.

Frequently Asked Questions
Defense installations often operate on "islands" of legacy technology that cannot be patched or replaced without massive operational disruption. These systems were built on the assumption of a "trusted perimeter," meaning they lack the ability to verify if a command (such as opening a breaker or stopping a cooling pump) is from a legitimate operator or a nation-state actor.
SIGA secures these legacy assets by monitoring Level 0 of the Purdue Model. Instead of analyzing network packets, SIGA monitors the raw electrical signals (I/O) traveling between the controller and the physical machine. This creates a "Source of Truth" that is physically impossible to spoof from a remote network. Even if an adversary has gained "God Mode" access to the SCADA network, they cannot change the laws of physics that SIGA is monitoring.
In a high-stakes HLS environment, mistaking a cyberattack for a simple hardware failure can lead to catastrophic delays in response. SIGA uses machine learning to establish the "Physical Baseline" of your mission-critical equipment.
Hardware Fault: The physical signal and the SCADA reporting both show a deviation (e.g., a motor burning out).
Cyberattack (The "Invisible" Attack): The physical signal indicates a dangerous state (e.g., a turbine overspeeding), but the SCADA display has been "frozen" or manipulated to show normal operations.
By comparing the Physical Reality (Level 0) against the Reported Reality (Level 2/3), SIGA identifies the "Expression Phase" of an attack, allowing Commanders to differentiate between a maintenance issue and active sabotage.
No. To achieve comprehensive process visibility and situational awareness, only a strategic subset of critical signals (typically just 3–10% of total I/O) needs to be monitored. This focused approach ensures the protection of the most vital infrastructure components while maintaining a robust security posture without excessive data overhead.
Most Zero Trust initiatives stop at the network level (identities and endpoints). SIGA extends Zero Trust to the Physical Layer. We operate under the assumption that the network will be compromised. By providing an out-of-band, unidirectional monitoring solution, SIGA ensures that your most critical physical processes are verified independently of the IT/OT network's integrity.
