Solution Brief
Industrial / OT Security

Passive Protocol Intelligence for Industrial Networks

WireTrace reads the actual commands flowing between PLCs, RTUs, HMIs, and SCADA systems - not just traffic metadata. Security and operations teams gain continuous visibility into what industrial controllers are doing, who is communicating with them, and whether that activity is authorized. Deployed passively with zero impact on safety-critical operations.

The Challenge

Industrial Assets Operating in the Dark

Legacy PLCs and RTUs were never designed to be inventoried by IT tools. Many have been running for years without appearing in any asset register. Shadow connections between Purdue levels go unnoticed until an incident exposes them.

Port-Level Tools Cannot Read Industrial Commands

Generic security tools see "traffic on port 502" but cannot distinguish a routine register read from an unauthorized write to a safety-critical setpoint. Without protocol-level context, real OT threats are invisible.

Active Scanning Disrupts Industrial Operations

Active network discovery tools have caused PLC faults, safety system trips, and production outages. In OT environments where uptime is measured in years, active interrogation is an unacceptable risk. Visibility must be entirely passive.

How WireTrace Solves It

Command-Level Protocol Dissection

272 DPI parsers decode Modbus function codes and register values, S7Comm PLC parameters, DNP3 control commands, EtherNet/IP CIP messages, and IEC 104 telecontrol sequences. Security teams see the actual operations being performed on controllers - not abstractions.

Passive + Active Industrial Asset Discovery

Every PLC, RTU, HMI, engineering workstation, and protocol gateway is identified from observed traffic. Optional SNMP polling (all versions supported) with per-device credentials enriches assets with hardware model, serial number, firmware version, and device identity fields. 411 classification rules across 68 device types.

AI Intelligence & Change Management

Built-in AI agent with 21 query tools answers natural language questions from real OT data in under 200ms. Ask Your Environment: "Which PLCs changed firmware this week?" Streaming reports generate progressively. Conversation memory for follow-up questions. Full change tracking with before/after audit trail. No GPU or cloud needed.

Ransomware Kill Chain & OT Isolation Detection

12 detection rules covering the full ransomware kill chain: port scanning, network enumeration, RDP spray, SMB enumeration, OT isolation violations, credential exposure, mass file operations, and data exfiltration. Kill chain correlation scores multiple indicators per asset for high-confidence alerts. MITRE ATT&CK mapped. Purdue Swim Lane View with device-type icons. Automatic gateway detection discovers hidden devices.

S7Comm

PLC model identification (S7-300/400/1200/1500), programming activity detection, diagnostic access, vendor and firmware extraction.

DNP3

Master/outstation role identification, control relay commands, analog and binary monitoring data, unsolicited responses, outstation addressing.

Industry Applications

Energy & Utilities

Continuous SCADA visibility across substations, distribution networks, and generation facilities. DNP3, IEC 104, and GOOSE/SV protocol intelligence for power grid operations. Detect unauthorized control commands and generate IEC 62443 and NERC CIP evidence from observed traffic.

Manufacturing

Monitor PLC communications across production lines and robotic cells. 12 ransomware kill chain detection rules identify reconnaissance, lateral movement, OT isolation violations, and active encryption before damage occurs. Detect unauthorized programming, firmware changes, and file operations across network shares. Track file activity across SMB and other protocols for forensic investigation.

Oil & Gas

Pipeline SCADA, refinery DCS, and offshore platform monitoring with Modbus, HART-IP, and FF-HSE protocol visibility. Identify unauthorized access to safety instrumented systems and maintain operational awareness across geographically distributed sites.

Water & Wastewater

Treatment plant and distribution network visibility with DNP3 and Modbus command-level inspection. Detect unauthorized setpoint changes to pumps, valves, and chemical dosing systems - the kind of activity that active scanning tools cannot distinguish from normal operations.

Compliance & Audit Evidence

WireTrace generates continuous compliance evidence from observed OT network traffic. Asset inventories, zone boundary communications, access control validation, and protocol usage documentation are always current - replacing periodic manual assessments that go stale between audits.

IEC 62443

Zone and conduit mapping from observed traffic. Access control evidence and communication flow documentation generated continuously.

NCA OTCC

Saudi OT Cybersecurity Controls. Asset inventory, continuous monitoring, and incident detection evidence from wire-level observations.

ISO 27001

Information security controls applied to industrial environments. Asset management, network security, and operational evidence.

Deployment

A single WireTrace sensor on a SPAN port or network TAP captures all OT traffic in a zone. The sensor is 100% passive - it never transmits on the monitored network. Multiple sensors cover multiple segments and report to a centralized server. Optional active enrichment (SNMP polling, network topology discovery with switch port mapping) adds hardware-level detail. Fully air-gap deployable. Server deploys in under 10 minutes. Platform images build in under 60 seconds for rapid updates. Adaptive storage retention keeps data as long as disk allows. First industrial assets classified in under 30 seconds.
