One line
NetVane is a private, local-first network scanner for Windows: it finds every device, shows what each one is exposing, and helps fix it, and nothing about your network leaves your machine.
Short
NetVane maps every device on a home or small-business network, identifies what each one is, and explains what it is exposing in plain language, then helps fix it, with consent, undo and an audit log. Vulnerability matching runs against a bundled NVD + CISA-KEV database entirely offline, ranked by real-world exploit probability. There is no cloud, no account and no agent, and an in-app egress ledger proves the “nothing leaves your machine” claim rather than asserting it. Free for one network forever; Pro is $19 once, Business $99 once.
Long
NetVane is a Windows network scanner and security monitor built on a contrarian premise: security software should not require surrendering your network's data to a cloud. Everything, discovery, device identification, vulnerability matching, scoring, history, runs on the user's own machine, and a live egress ledger in the app shows exactly how many outbound requests were made (“0 internet requests” during a scan) so the privacy claim is auditable rather than rhetorical.
A scan discovers every device, names it (“Ring doorbell”, “Sonos speaker”) using an offline fingerprint table, and surfaces exposures with plain-language explanations and step-by-step fixes. Detected service versions are matched against a bundled NVD + CISA-KEV database, known-exploited issues first, then ranked by exploit probability (EPSS). Findings can be actively validated with non-destructive probes, and a class of exposures can be fixed with one click, every action consented, snapshotted, undoable and logged. Paid editions add unattended monitoring: scheduled scans, new-device and change alerts, and, in Business, a compliance evidence report and an evidence pack with an integrity checksum for consultants and small businesses. Pricing is one-time ($19 Pro / $99 Business); the free edition covers knowing your network, permanently, with no account.
Claims you can verify yourself
- “Nothing about your network leaves your machine”, watch the in-app Local-only panel's egress ledger during a scan; it counts every outbound request the app can make.
- Offline vulnerability matching, disconnect from the internet and scan; CVE/KEV results still appear (the database is bundled).
- Under 25 MB, signed, check the installer's size and its Authenticode signature (publisher: GRCSAC) in Properties → Digital Signatures.
- No admin rights, the per-user installer never triggers UAC.
- Licences verify offline, activation works on a machine with no internet connection.
What NetVane is not
Honest scoping beats a takedown of your review. NetVane is not an enterprise vulnerability-management platform, not a penetration-testing tool, and not feature parity with Nessus, our own comparison page says where Nessus is stronger. It is the useful core, exposure, vulnerability intelligence, prioritisation, remediation, for the networks that will never buy a $4,790/year scanner.
