Agentic Security Engineering · for defenders

Master Agents for
Defensive Security

Security work is changing, and defenders need more reach. Learn to use agents to amplify your own abilities and systems, with your judgment at the center.

How we teach

The instructor

Faan Rossouw

Faan Rossouw

Founder

I’ve taught thousands of defenders how to find adversaries in network and endpoint telemetry.

I see the agentic era as a genuine turning point for security. I built AionSec to help you understand these systems, make informed decisions about them, and build with them.

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.
