See what's on your network,
and what it's exposing.
NetVane finds the devices on your network — phones, laptops, cameras, smart‑home gadgets — and draws it as a live map: what each device is, how it connects, and what it's exposing, with plain‑language fixes. 100% local: your network data stays on your machine.
Windows installer (per‑user, no admin) or portable · no dependencies · opens a dashboard at 127.0.0.1:8787
Everything a scanner should do — without the complexity
No cloud, no account, no agent. One app, one dashboard, everything on your machine.
Discover & map
Finds your devices, identifies each one's type, vendor and OS, fingerprints open ports, and draws a live topology map. A built‑in engine needs nothing installed; nmap is optional for deeper detail.
Score & fix exposure
Flags reachable services, matches their versions against a bundled NVD + CISA‑KEV database offline (known‑exploited first, then ranked by real‑world exploit probability), confirms which exposures are real, and gives step‑by‑step fixes with the version to upgrade to.
Track change over time
Shows what exposures opened or resolved, which devices arrived or left, and how your security score moved — network‑wide and per device.
See it in action
Sixty seconds, no sign-up: a scan, the score, the map, and a finding opened to its fix. Recorded against demo data — no real network.
risk:high.
Signed, and checkable
The installer and the app are code-signed as GRCSAC, so Windows names the publisher. Check it yourself in Properties → Digital Signatures.
14 days of everything
Every install runs with full capability for 14 days — no account, no card, nothing to cancel. After that it stays free forever for a single network.
Buy it once, or not at all
Free is a real edition, not a trial. Pro and Business are one-time purchases, never subscriptions. See the editions.
Three steps to a safer network
Run it
Launch NetVane — it opens a dashboard in its own app window. No sign‑up, no config files.
Scan
Point it at your network and pick a depth. Devices, ports and OS appear as they're found.
Fix
Review your score and work the ranked, plain‑English fix list. Re‑scan to confirm.
Your network map never leaves the building
No cloud, no account, no telemetry, no analytics. NetVane runs entirely on your machine — and it proves it: the dashboard shows a live ledger of every outbound request the app makes, so you can verify the privacy claim instead of trusting it.
Read the output before you install it
NetVane produces documents you act on and hand to other people. Both samples below are real output, generated from the demo network.
The security report
A ranked priority action plan, exposures by device, accepted risks and the full inventory — in every edition, free included.
Compliance evidence · Business
Scope, findings, accepted risks with reasons, every change with its audit trail, and an integrity hash — for assessments and client work.
