Build your own
agentic defense.
Learn agentic security engineering: how to integrate an
agentic layer into a defensive security system.
Then build it for your own environment.
One intrusion, raw telemetry to grounded report — and you build every part of the system that hunts it.
What you leave with isn't a tool or a vendor's stack: it's a way of thinking you apply to your own environment — including the judgment of where an agentic layer doesn't belong.
Build Your Own
Agentic Defense
One complete agentic defense system, built end to end on a single intrusion — from raw telemetry to a grounded, evidence-cited report, through the interface that feeds it data, the skills that shape its judgment, and the graph that gives it memory.
Faan Rossouw
Faan has taught thousands of defenders how to find adversaries in network and endpoint telemetry. He sees the agentic era as a genuine inflection point for security — and built AionSec to give defenders the discipline to meet it.
One of the best training classes I've taken in years. As someone who has been using Agentic AI on a daily basis since late last year, I can confidently say this class is for all levels. The labs have a great flow. I paid for this class myself and I'm glad that I did.
Faan's in-depth knowledge and his amazing way of explaining things in the KISS format makes complex topics genuinely accessible. I highly recommend his trainings and will definitely be attending more sessions.
I've attended all of Faan's workshops, and you can tell he's passionate about what he's talking about. I'd participate in any of Faan's trainings with my eyes closed.
It's a rare pleasure to encounter a teacher with the alacrity, patience, and capacity to package such dense subject matter in such an accessible format as Faan.
The course is clear, well-structured, and presented with a strong, confident grasp of the material. If you want to learn agentic AI and apply it to security in a methodical and hands-on way, he's someone who can genuinely help you deepen your understanding and elevate your practice.
Each lesson is well designed to bring students of all levels up to speed and make complex concepts digestible. His experience and passion impart a contagious desire for learning—fun and thoughtful while maintaining lightheartedness through high-level technical material.
Very well presented. I would sign up for any future courses by Faan in a heartbeat.
Your passion for this is obvious, and it made the practical stuff actually stick. Thanks, Faan.
Start building.
The discipline of building AI-driven defensive systems properly: deterministic code where the work is mechanical, an agentic layer where judgment is needed, and the human above both. We make the full argument in Agentic Security Engineering.
The craft half of it. A harness is the deliberate orchestration of three collaborators — human judgment, agentic reasoning, and deterministic code — each used only where it is strongest. Applied harness engineering is designing and building that orchestration for your own environment, and it's the skill the course teaches.
Threat hunters, SOC analysts, detection engineers, and security leads who would rather build their own agentic layer than adopt whatever a vendor ships.
One flagship course — Build Your Own Agentic Defense. Seventeen modules, one complete agentic defense system built end to end, and a repository that's yours to keep. Around it: a private community, monthly live Q&A, and lifetime access with every future update.
