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.
Quick start
One curl. Then run it.
curl -fsSL https://32north.ai/dl/mss-macos-arm64 -o mss && chmod +x mss
./mss scan --target 192.168.1.0/24Prebuilt binaries for macOS and Linux; Windows via WSL2. Full install lines for every platform, plus checksums, are on the download page.
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.
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.
