- Cybersecurity learners and network defenders
- Worth noticing
- Defender view hides the attack timeline; it shows only activity recorded by the scenario’s configured sensors.
Field notes
Build mode exposes editable nodes, links, boundaries, sensors, and attack steps; node positions can also be entered as coordinates rather than dragged. The AI-assisted drafting flow uses a prompt copied into an AI service the user already uses, then checks the pasted reply, so the page says nothing is sent from the simulator. Changes restart the scenario and require JSON copy or download to preserve the draft.
