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.
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.
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. 250+ protocols, each decoded to full depth, on a 427-rule classification engine.
Passive. Never a risk to the process.
No agents on controllers. Passive by default - WireTrace connects to a SPAN or tap and reads only, live from the first packet. Active discovery is strictly opt-in, allow-listed and rate-limited, so it never reaches a controller you have not cleared. Nothing injected on the wire, no cloud dependency, air-gap friendly - safe for the most fragile industrial network.
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.
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, correlated to known CVEs for the OS and software each device actually runs, and rolled into one prioritised risk score.
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. Purpose-built detectors catch adversary-in-the-middle attacks - TCP reset injection, DNS manipulation and TLS interception - the moment they appear. Everything correlates into one detection view, mapped to MITRE ATT&CK for ICS.
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. Every result is cryptographically signed at the point of capture, so the evidence is tamper-evident and defensible. Investigation in minutes, not days.
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 (ISA/IEC 62443), NCA OTCC, NERC CIP, ISO/IEC 27001 and the NIST Cybersecurity Framework (CSF).
Proven in production at a national electricity distribution company.
