Try It
Real Terminal in Your Browser
No setup, no VM. Practice Linux commands directly on the platform.
Scenarios
Guided incident & pipeline drills
Short story-driven paths layered on the core curriculum—the same rhythm: briefing, hands-on terminal work, and checked steps.
SecOps incident mini-flow
Catch a signal, triage with guidance, write it up—practice detect → triage → document without a production war room.
CI/CD pipeline drill
Follow one thread: rescue a pipeline from lint through tests to a sandboxed deploy—so the course feels like a single fix-it mission.
