How it works

Read. Do. Keep.

Every module runs the same rhythm — you're never just reading. The depth comes from the bridge, the lab, and the automation you build and own.

STEP_01

Read the bridge

Original prose builds the mental model and the practitioner translation — then a curated, time-boxed Learn path to the best existing explanations. We curate the basics; we write the judgment.

STEP_02

Do the lab

A one-command environment — git clone + make up. Attack a real target, build a real detection, carve a real disk. Then Automate & own it: turn the manual work into a script you can reproduce by hand.

STEP_03

Keep the artifact

No paywalled exam — your portfolio is the credential. Each lab ends in an artifact you commit to your own repo, with a make check you run yourself to prove your fix works. Every track ends in a capstone worth showing.

Career paths

Pick the job.
We'll order the tracks.

Every path starts at Foundations and ends in capstones you can put in front of a hiring manager. Tracks stand alone — this is a recommended order, not a gate.

Learning Tracks

Pick your path.
Own the domain.

Structured, hands-on paths from zero to job-ready. Every track uses the real tools you'll use on the job — open source first — with AI woven through as the force multiplier. All 13 tracks are live — 178 modules, every one with a validated lab environment.
