Penetration Testing Done Methodically

Reconnaissance, web app exploitation, network testing, post-exploitation, and writing reports clients actually read. Built on real methodology — PTES, OWASP, and the tools professionals use on actual engagements.

No videos. On purpose.

This is a text-first course that links out to the best supporting material on the internet instead of trying to replace it. The goal is to make this the best course on pentesting you can find — even without producing a single minute of custom video.

Practitioner-tested, not vendor marketing

This course is built by engineers who ship pentesting systems for a living. It reflects how these tools actually behave in production — not how the documentation describes them.

Code you can run, not demos to watch

Every day includes working code examples you can copy, run, and modify right now. The goal is understanding through doing, not passive reading.

Links to the canonical sources

Instead of re-explaining existing documentation, this course links to the definitive open-source implementations and the best reference material on pentesting available.

Completes in 5 one-hour sessions

Each day is designed to finish in about an hour of focused reading plus hands-on work. Do the whole course over a week of lunch breaks. No calendar commitment, no live classes.

The 5 Days

Each day stands alone. Read them in order for the full picture, or jump straight to the day that answers the question you have today.

The best external videos on this topic.

Instead of shooting our own videos, we link to the best deep-dives already on YouTube. Watch them alongside the course. All external, all free, all from builders who ship this stuff.

Read the source.

The best way to deepen understanding is to read the canonical open-source implementations. Clone them, trace the code, understand how the concepts in this course get applied in production.

Three kinds of people read this.

Security Engineers and Defenders

Understanding how attackers think and operate makes you a better defender. This course teaches the offensive techniques that drive defensive tool design.

Developers Who Want to Test Their Own Apps

The best time to find a SQL injection in your app is before an attacker does. This course teaches you to test your own code with professional-grade tools.

Anyone Pursuing Security Certifications

OSCP, CEH, and CompTIA PenTest+ all require hands-on exploitation knowledge. This course builds the practical foundation those exams test.
