Notes that became guides.
Mavrixanix is a small, independent publisher of PDF guides to cybersecurity. We don't have a course platform, a certificate, or a community forum — just guides, written to be read once and kept as reference.
Where this started
The first guide we wrote was for two analysts joining a small security team without a formal training budget. Most courses we found either stayed abstract or handed over tools without explaining what they did. We wrote something more concrete instead, and kept doing that as the topics got harder.
What we actually sell
Ten PDF guides, priced individually, covering cybersecurity from networking fundamentals through to a full, authorized penetration testing methodology. Nothing is bundled behind a subscription, and nothing is sold on urgency — the catalogue looks the same today as it will next month.
What we don't promise
We don't promise a job, a certification, or a salary figure. What each guide promises is narrower and more honest: a specific set of topics, explained clearly, with labs you can run yourself in an environment you control.
On ethics and legality
Guides that cover offensive techniques — vulnerability testing, malware analysis, penetration testing — are written explicitly for isolated labs and authorized, permitted engagements. We say so plainly inside those guides, not as a disclaimer buried in fine print.
How the guides are written
Every guide starts as a working lab, not prose. We build and test each exercise first, then write the explanation around it. If a lab doesn't run cleanly on current, freely available tools, it doesn't go in the guide.
