OT / ICS · Critical infrastructure

Secure the plant floor.
Without touching it.

You can’t put an agent on a PLC, and an active scan can take a process down. WireTrace listens to the OT traffic already on your network - passively, on-premises - and turns it into a complete asset inventory, deep protocol visibility and continuous IEC 62443 and NCA OTCC evidence.

Visibility

Every controller, seen.

PLCs, RTUs, HMIs, SCADA servers, drives, safety systems and field sensors - discovered and classified into one live inventory, automatically, from the traffic they already send. No agents, no scans, no plant walk-downs.

Protocol Intelligence

We speak the plant floor.

Modbus, DNP3, S7comm, EtherNet/IP, PROFINET, OPC UA, IEC 60870-5-104 and BACnet decoded at the wire. Not port numbers - the actual register values, function codes and commands, across a 411-rule engine and 272 protocol parsers.

Safe by design

Passive. Never a risk to the process.

No agents on controllers. No active scanning that could disrupt a live process. Nothing injected on the wire, no cloud dependency, air-gap friendly. WireTrace connects to a SPAN or tap and reads only - safe for the most fragile industrial network, live from the first packet.

Segmentation & Policy

Enforce the Purdue model.

Prove IT and OT stay separated and that each Purdue zone is isolated - validated live, not assumed. Codify the communications each zone is meant to have and be alerted the moment a cross-zone flow or unexpected conversation appears.

Exposure

Find real OT exposure.

Cleartext credentials, unauthenticated industrial protocols, exposed engineering and management interfaces, weak crypto and rogue remote access - surfaced passively from observed traffic and rolled into one prioritised risk score.

Threat Detection

Catch unauthorized commands.

Per-device behavioural baselines flag what should not be there: rogue flows, new assets, cross-zone violations, unauthorized PLC writes and logic downloads, and ransomware behaviour - mapped to MITRE ATT&CK for ICS.

Forensics

Command-level evidence, immediately.

Reconstruct which commands hit a PLC, which logic was downloaded, which certificates were negotiated and which devices communicated - before, during and after an event. Investigation in minutes, not days.

Compliance

IEC 62443 & NCA OTCC, continuously.

Audit-ready evidence generated from live traffic instead of manual assessments: asset inventory, zone segmentation proof, access control and exposure. Mapped to IEC 62443, NCA OTCC, NERC CIP, ISO 27001 and NIST CSF.
