Every device on a network announces itself continuously. It negotiates certificates, answers discovery requests, identifies its vendor and firmware, and issues commands that describe exactly what it does for a living. That information is already crossing the wire, in the clear, every second of every day.
Most security tools skim it. They record that two addresses exchanged traffic on a port and move on. WireTrace reads what was actually said, and turns it into an inventory you can trust, exposure you can act on, and evidence you can hand to an auditor.
The devices that carry the most risk are the ones your existing tools cannot reach. A protection relay will not run an agent. An infusion pump will not accept one. A twelve-year-old PLC running a production line will fault if you scan it, and the plant manager is right to refuse. So the estate splits in two: the part that is managed and visible, and the part that is neither, which is usually where an incident starts.
Asking those devices what they are is the wrong move, and in safety-critical environments it is a dangerous one. They are already saying it. The question is whether anything on the network is listening closely enough to understand.
WireTrace connects to a SPAN port or a network TAP and observes. It transmits nothing onto the monitored network, installs nothing on any device, and asks no device any question. From that vantage point it reads protocol conversations in depth and builds a continuously updated picture of the environment: what each device is, who made it, what firmware it runs, what it talks to, what it is being told to do, and whether any of that has changed.
Vendor, model, role, firmware and identity established from what devices say on the wire, including the unmanaged and undocumented ones nobody put in the CMDB.
Which device actually talks to which, over what protocol, in which direction. The map of the network as it behaves, rather than as the design document claims.
Cleartext credentials, weak certificates, exposed management paths and unprotected industrial protocols, found because they were seen, not because a scanner guessed.
Control evidence assembled continuously from observed communications, so an audit becomes a report to review rather than a project to staff.
PLCs, RTUs, drives, protection relays, historians and engineering workstations, watched without touching the process.
Servers, endpoints, network infrastructure and the shadow systems that never made it onto anyone's list.
Cameras, access control, building management, printers and the long tail of connected equipment nobody owns.
Infusion pumps, imaging systems, patient monitors and diagnostics, where a scan is a clinical risk.
The value of reading protocols properly shows up in questions that are normally hard to answer, and that WireTrace answers from traffic alone.
Make, model and firmware version established from how a device identifies itself in its own protocols, on equipment that would fault under a scan and will never run an agent.
Not that a port is open, but which commands are being issued, to which device, by whom, and whether that pattern is what it was yesterday.
Zones are enforced on paper and eroded in practice. Observed traffic shows which boundaries are real and which have quietly been crossed.
Control evidence drawn from what the network actually did during the assessment window, with the observation behind every statement.
Rumi, the WireTrace assistant, runs entirely within the customer environment. No cloud service, no external call, no data leaving the boundary.
Contractor equipment, forgotten test rigs, replaced hardware still connected. If it speaks on the network, it appears in the inventory.
There is no active mode to leave switched on by accident. WireTrace observes; it does not interrogate. That is what makes it safe on a production line and on a clinical network.
Fully self-contained. No cloud dependency and no data leaving the network, which is what regulated, national and defence environments require before a conversation can even start.
Designed to run in isolated networks with no outbound path, including the analytics and the AI assistant. Isolation does not have to mean going without modern tooling.
Connect to a SPAN port or TAP and assets begin appearing and classifying within minutes. No agent rollout, no scan window, no change freeze to negotiate.
| You need to | WireTrace gives you |
|---|---|
| Know what is on the network | A live inventory built from observed behaviour, including everything agents and scanners cannot reach. |
| Reduce real exposure | Weaknesses that were observed in traffic, prioritised by what is actually reachable and actually running. |
| Satisfy a regulator | Continuous control evidence drawn from communications, mapped to the frameworks you are assessed against. |
| Detect what does not belong | Changes in device behaviour and communication relationships, with the protocol context needed to judge them. |
| Understand your estate physically | Where devices actually sit, how they are connected, and what a path between two of them really traverses. |
The fastest way to judge WireTrace is to point it at a live segment of your network and look at what comes back within the hour. We will show you the inventory it builds, the exposure it finds, and the evidence it produces, using your environment rather than a demonstration dataset.
