Utilities · Marine Security Scanner

Scan your boat's network from your laptop.

The Marine Security Scanner runs over the boat's network from any laptop on the same LAN. It identifies every device, checks it against 32°N's advisory corpus, and tells you which ones have known issues. Five minutes, no install on the boat.

Download the CLI

Quick start

One curl. Then run it.

curl -fsSL https://32north.ai/dl/mss-macos-arm64 -o mss && chmod +x mss
./mss scan --target 192.168.1.0/24

Prebuilt binaries for macOS and Linux; Windows via WSL2. Every build and its checksum is listed below.

What it scans for

Marine-specific, not generic.

The scanner uses 32°N's own signature pack, driven by the published advisory corpus — SignalK plugin issues, OpenCPN binary problems, NMEA-2000 gateway exposures, common bridge and AIS misconfigurations. It's not a generic network scanner wearing a marine sticker.

Download

Every build, and its checksum.

Static binaries, no runtime to install. Verify the checksum before you run it — the whole point of the tool is not trusting things you did not check.

BuildBinaryChecksum
macOS · Apple siliconmss-macos-arm64.sha256
macOS · Intelmss-macos-x64.sha256
Linux · x86-64mss-linux-x64.sha256

Windows runs it under WSL2 using the Linux build.

Why it's separate

A binary, not an account.

This is the tool I run against my own boat's network before I plug anything new in. It's a single static binary — no 32°N account, no install on the boat itself — open source under MIT, same as the rest of 32°N.
