UNDERSTAND BY
SEEING IT HAPPEN.

Reading about SQL injection doesn't make it real. Watching it happen in a live simulation does. Every lesson walks you through the attacker's perspective first — then shows you exactly how to stop it.

Then it shows you how to build the defence — with real, production-grade code patterns.

01 — ATTACK
Run the exploit yourself. See exactly what breaks and why.
02 — UNDERSTAND
Live code previews and visualizations explain the root cause.
03 — DEFEND
Implement the fix. Test that your payload no longer works.
