Hack and secure systems like a professional — a hands-on, lab-driven journey from networking and Linux fundamentals to recon, exploitation, web and OWASP Top 10, privilege escalation, Active Directory, cloud, and blue-team defense.

This is a complete, hands-on ethical hacking bootcamp that takes you from the fundamentals to professional-level offensive and defensive security — entirely through practical, lab-based work. You will build a safe, isolated lab and then run the full penetration-testing lifecycle the way real assessors do: reconnaissance, scanning and enumeration, vulnerability analysis, controlled exploitation, privilege escalation, and clear professional reporting.
Every offensive technique is demonstrated against intentionally vulnerable, isolated lab targets, and every lesson pairs concepts with a terminal-driven, hands-on task, a real-world case study, and a knowledge check. The course balances red-team offense with blue-team defense so you understand both how attacks work and how to detect and stop them.
For authorized, educational use only. You will only test systems you own or have explicit written authorization to test. Unauthorized access to computer systems is a crime.
Aspiring penetration testers, security analysts, IT professionals, and developers who want to understand attacks deeply enough to defend against them. Networking and Linux basics are taught from the ground up, so motivated beginners can follow — but the course goes all the way to advanced, professional techniques.

Kai has spent 12 years on the offensive side of security — running red-team engagements, chaining recon into exploitation, and writing the reports that actually get vulnerabilities fixed. He lives on the Linux command line, automating tradecraft in Bash, and teaches security the way it is really practised: hands-on, methodical, and strictly ethical, so you understand the attacker mindset well enough to defend against it.
Enjoyed it a lot. Practical and easy to follow — just wished a couple of topics went deeper.
A reliable, well-made course. Lost half a star for a couple of audio/example hiccups, but still recommended.
The best money I have spent on learning this year. Clear, modern, and no fluff.
An okay starting point. Clear enough, just not as comprehensive as I was hoping.
