A unified OT intrusion detection system and cyber-physical systems IDS platform that combines deep protocol intelligence, behavioral detection, and federated architecture to protect critical infrastructure at any scale.
Seven core capabilities working together to deliver comprehensive OT and CPS intrusion detection
Analyze traffic at the protocol level across 30+ industrial protocols including Modbus, DNP3, IEC 104, OPC UA, and S7comm.
Machine learning models trained on industrial baselines detect anomalies, misconfigurations, and zero-day threats in real time.
High-performance packet processing built on customized Suricata with OT-specific rulesets and signature matching.
Passively discovers every device on your network, classifies it, and maps it to the Purdue Model without sending a single packet.
Define, deploy, and enforce security policies across distributed sensor networks from a single management plane.
Deploy sensors across sites and regions with centralized management. Each node operates autonomously during connectivity loss.
Passively identified assets are matched against ICS-CERT, NVD, and vendor advisories with OT-context risk scoring that factors in Purdue level, process criticality, and compensating controls.

+ additional protocols added regularly based on customer environments
A structured deployment process designed around operational safety and zero disruption
Install passive network sensors on SPAN/mirror ports. No inline placement, no network changes, no risk to operations.
Within minutes, NETRUDER maps every device, connection, and protocol on your network without sending any traffic.
AI models learn normal operational patterns specific to your environment over a 2-week training period.
Full detection, alerting, and compliance reporting goes live with policies tuned to your operational context.
NETRUDER connects to the tools your security team already uses. Forward alerts, enrich tickets, and trigger response workflows without changing your operations playbook.
Bi-directional SIEM integration with alert enrichment
REST API for custom integrations and automation
Syslog and CEF for legacy tool compatibility
SOAR playbook triggers for automated response
NETRUDER identifies every device on your network by analyzing traffic patterns, protocol behaviors, and metadata — without sending a single packet. No active scanning. No operational risk.
Identifies devices by analyzing unique protocol behavior patterns — Modbus function code sequences, S7comm CPU identification handshakes, DNP3 object variations, and IEC 104 ASDU type distributions.
Extracts device identity from passive network characteristics including TCP window sizes, TTL values, MAC OUI resolution, packet timing intervals, and connection establishment patterns.
Parses application-layer payloads to extract firmware versions, model identifiers, configuration parameters, and module inventory without sending any queries to the device.
Our multi-layered fingerprinting pipeline combines protocol analysis, network heuristics, and application metadata to achieve industry-leading accuracy across diverse OT environments.

Active scanners send probes that can crash legacy PLCs and disrupt safety controllers. NETRUDER achieves comparable or better identification accuracy using only observed traffic. Read our full passive vs. active asset discovery decision framework.
NETRUDER Passive | Traditional Active Scan | |
|---|---|---|
| Network Impact | Zero packets sent | Generates scan traffic |
| OT Safety | No risk to operations | Can crash legacy PLCs |
| Device Identification | 98.5% classification accuracy | ~90% with banner grabs |
| Firmware Detection | Extracted from traffic metadata | Requires direct queries |
| Coverage | Every communicating device | Only IP-addressable devices |
| Deployment | SPAN port — minutes | Agent or scanner — days |
Not just "CVE-2024-XXXX affects this IP" — NETRUDER tells you "CVE-2024-XXXX affects this Siemens S7-1500 running firmware v2.9 on your chemical dosing loop at Purdue Level 1, and it is reachable from the DMZ."
Passive identification extracts device type, vendor, model, firmware version, and Purdue level from observed traffic.
Fingerprints are matched against ICS-CERT, NVD, and vendor-specific advisory databases (Siemens ProductCERT, Rockwell, Schneider).
Each vulnerability is enriched with operational context: Purdue level, process criticality, network exposure, and compensating controls.
A composite risk score factors in exploitability, operational impact, blast radius, and existing mitigations to drive focused remediation.
NETRUDER continuously ingests vulnerability intelligence from authoritative OT/ICS advisory sources to ensure complete coverage.
Risk scores incorporate operational context that generic CVSS cannot capture. A low-CVSS vulnerability on a safety controller may score higher than a critical CVE on a non-essential historian.
A vulnerable device at Level 1 controlling a safety function is scored higher than the same CVE at Level 4.
Vulnerabilities on devices controlling chemical dosing, turbine governors, or safety interlocks receive elevated priority.
Risk is weighted by whether the vulnerable asset is reachable from the IT/OT boundary, external VPN, or only the local control network.
Existing mitigations — firewall rules, VLAN segmentation, access restrictions — are factored in to reduce the effective risk score.
Unlike quarterly vulnerability assessments, NETRUDER correlates CVEs against your live asset inventory in real time. When a new advisory drops, every affected asset is flagged within minutes — with full operational context already attached.
NETRUDER goes beyond framework logos. Every alert and asset is continuously evaluated against specific regulatory controls, with automated evidence collection, gap tracking, and export-ready audit packages.
NETRUDER continuously captures audit-relevant data — asset inventories, access logs, configuration snapshots, alert histories, and network topology changes — without manual effort.
Every event and asset state is automatically mapped to specific controls within IEC 62443, NIST 800-82, NERC CIP, and NIS2. See exactly which controls are satisfied and which have gaps.
Identify unmet controls, assign remediation owners, track progress, and receive alerts when compliance posture degrades or drift is detected.
Generate comprehensive compliance reports in PDF and CSV formats with full evidence trails, ready for regulatory submission or third-party audit review.
Dual-tier storage architecture designed for the realities of industrial deployments — maximizing hardware lifespan while keeping critical data instantly accessible.
High-speed, low-latency — current operational data
High-capacity archival — historical and compliance data
OT and ICS deployments demand hardware that survives. Tiered storage keeps the IDS running longer with fewer hardware interventions — whether you're on a factory floor or a remote substation.
By offloading aged data to HDD, write cycles on the SSD are dramatically reduced — critical for hardware longevity in OT environments.
Industrial control system environments expose hardware to vibration, heat, and dust. Tiered storage reduces mechanical and thermal stress on active drives.
Recent traffic, live alarms, and OS state remain on SSD for sub-millisecond retrieval — keeping detection and response latency minimal.
Define how long data stays on hot storage before automatic migration. Balance performance, capacity, and compliance requirements per deployment.
Performance claims backed by controlled lab testing and real-world customer deployments
