A hands-on course where you write a working security tool in every lesson. It runs in your browser and installs on your phone, no setup, no environment hell. Every lesson is a mission: clear the checks, earn XP, and rank up from Recruit to Architect. Built to win the fight against your phone, not lose it.
# count failed logins per IP, alert past the threshold from collections import Counter fails = re.findall(r"Failed password .* from (\d+\.\d+\.\d+\.\d+)", log) for ip, n in Counter(fails).most_common(): if n >= THRESHOLD: print(f"[ALERT] brute force from {ip} ({n} fails)") >>> [ALERT] brute force from 45.33.12.1 (14 fails) PASS // +150 XP · rank up: OPERATOR
Generic courses teach syntax in a vacuum. You grind through variables and loops with examples that have nothing to do with the work you actually want to do. By the time anything feels relevant, the momentum is gone and the tab is closed.
Security work does not look like a calculator app. It looks like parsing a messy log, fingerprinting a file, flagging a brute-force attempt, pulling threat intel on an IP, and breaking weak crypto. So that is what you build here, from the very first module.
You learn the concept, then immediately use it to build something a security analyst would actually run. No filler projects.
The whole course is a live Python environment in your browser. Hit Run, see output. Add it to your home screen and it works like an app.
Every exercise runs your code and returns PASS or FAIL, the way real tests do. You always know if you got it right.
The path goes from print() to a working triage engine and a cloud security pipeline, security-first the whole way. By the end you have written:
The runtime loads once through WebAssembly. You are running genuine Python, not a watered-down simulation.
Open the link, add to home screen on iPhone or Android, and it launches full screen and works offline.
Completed lessons and exercises are tracked on your device, so you can pick up where you left off.
Buy once. New lessons and fixes land at no extra cost.
Most learning apps lose to the group chat and the feed. This one borrows the same loops that keep you scrolling and points them at something useful. Clear a lesson, watch the XP land, climb the ranks. You are not grinding through a course, you are running ops.
Pass a check, earn XP. First-try clears pay more. Your rank climbs as your skill does, from Recruit all the way to Architect.
Come back, keep the chain alive. Ten focused minutes a day beats one heroic session you never repeat.
Unlock badges for real milestones: first blood, clean first-try runs, clearing the crypto and detection ops.
Finish the course and earn a shareable certificate stamped with your callsign and final rank. Proof you built it, not watched it.
Built by Zach Marcy. Two decades in IT, six years in cybersecurity, working as a senior security architect. He teaches cloud, AI, and API security through real projects at HackWithZach. The teaching method here is the same one he uses on real systems: build it small, secure it, then break it yourself.
This is the on-ramp, not the whole journey. Once you can write tools in Python, the next step is securing the systems everyone is now building on AI. That is what the AI Security Engineer course covers, and Python for Security is where it starts.
