Dethernety documentation

Guides for the platform, its modules, the Dethereal plugin and the BYODt cloud — from your first model to running it on your own infrastructure.

Your first threat finding in minutes

Run the platform on your own machine, draw a small model and see the threats on the routes to your data.

01Install with one command
02Draw four elements and their flows
03Open the Threat Report

You need Linux or macOS (Windows: WSL), Docker or Podman with more than 4 GB for its VM, and Node.js 18+ for the installer (without it, get-byodt.sh). The first install downloads a few GB: allow 30–60 minutes, mostly unattended. Drawing the model and reading its first finding then takes about 10 minutes.
