ScanWRX by CompanyWRX

Know what is on the networkbefore you touch it

ScanWRX sweeps a subnet in seconds, identifies what it found and shows you why it thinks so, and tells you exactly what changed since last time. Built for the technician who has to explain the answer afterwards.

An example network. The last row reported nothing about itself, so ScanWRX names no manufacturer and no model rather than guessing one.

Measured on a real 80-device network: 80 devices in 8 seconds, a /24 over Wi-Fi, without administrator rights.

Why this one

Most scanners give you a list. This one gives you an argument you can check.

It never guesses out loud

Every identification carries a confidence label and the evidence behind it. A device that reported nothing about itself is shown as unknown — not as a plausible-looking model number you would have to disprove in front of a client.

A device is its MAC, not its address

When DHCP moves something, ScanWRX reports one change: it moved. Tools that key on the IP report a removal and an addition, and you spend the afternoon chasing a device that never left.

It does not need administrator

No driver, no packet capture, no elevation prompt, no antivirus argument. It uses the Windows networking APIs that are there for this, so it runs on a locked-down machine you were handed ten minutes ago.

From nothing to a document in four steps

There is no project to create, no agent to install and no inventory to seed first.

Point it at a network

It reads your adapter and offers the subnet you are on. Type a different one if you want. No configuration, no profile to build first.

Watch it fill in

ARP, ICMP, TCP, mDNS, SSDP, WS-Discovery and NetBIOS run together. Results appear as they arrive rather than after everything finishes.

Read the evidence

Open any device to see which probe said what. The identification is an argument you can check, not an answer you have to trust.

Leave something behind

Export CSV or JSON on the free tier. Pro produces a PDF with your details on it that a client can actually keep.

What it does

Six things, each done properly

All features

Network discovery

Sweep a subnet and see every device that answers, with latency and open services.

Device identification

What each device is, how confident that is, and the evidence behind it.

Change detection

Compare a visit against the last one. A device that moved is one change, not two.

Documentation and reports

PDF and CSV built for handing to a client, with your details on them.

Switch port mapping

Read a managed switch's own forwarding table over SNMP, using your credential.

Troubleshooting tools

Ping, traceroute, DNS, port checks and Find Device, in the same window.

The rule the product is built on

ScanWRX will tell you it does not know.

A scanner that always produces an answer is producing some answers it made up. That is fine until you put one in a document with your name on it.

So a model number appears only when the device reported that model itself. Anything inferred from a MAC prefix, an open port or a service banner is capped below “confirmed” and labelled with the evidence it came from. A randomised MAC is never attributed to a manufacturer. And when Find Device catches two disconnections at once, it names neither and shows you both.

How identification works

Confirmed

The device reported this model itself, over mDNS, SNMP or its own web interface.

High confidence

Several independent signals agree. Inference is capped at 85% no matter how many agree.

Likely

One signal, usually the MAC manufacturer plus an open port. Worth checking.

Unknown

It answered, and said nothing about itself. Shown as an address, with no invented name.

Pricing

The free tier is a real tool, not a demo

No trial clock, no device cap, no watermark across the results, no nag on launch. If you scan one network occasionally, ScanWRX Free is the whole product for you and you never need to create an account.
