What I Talk About

Each talk is tailored to your audience. These are starting points, not scripts. I also build custom CTFs and training programs from scratch.

01

How Attackers Use AI (And What Your Team Should Do About It)

AI is changing the speed and scale of attacks. I walk through real examples of AI-powered phishing, reconnaissance, and vulnerability discovery, drawing on my background in AI security research and the tools I build and use daily.

For: CISOs, Security Teams, Executive Leadership
02

AI-Powered Red Teaming: The New Offensive Playbook

How AI tools change the pen testing workflow. From automated recon to AI-assisted exploit development. Live demos of tools I've built and use in real engagements, informed by hundreds of pen tests across every assessment type.

For: Security Conferences, Red Teams, Pen Testers
03

Supply Chain Security: Open Source, AI, and What's Next

How attackers compromise the software you trust before it ever reaches your environment. I cover real supply chain attacks, the growing role of AI in both attacking and defending the pipeline, and what your team should be watching for.

For: DevSecOps, Engineering Leadership, CISOs
04

When the Pen Test Goes Sideways

The elevator that locked me between floors. The badge clone that worked a little too well. 20 years of breaking into companies means 20 years of things not going to plan. Your audience will laugh, cringe, and leave thinking differently about their own security.

For: All-Hands, Security Awareness, Company Events
05

Social Engineering: The Human Attack Surface

Phishing, pretexting, physical infiltration. I've cloned badges, talked my way past front desks, and built phishing campaigns that bypassed every technical control. I show your audience exactly how it works and what makes people fall for it.

For: Security Teams, HR, Company Events
06

Privacy at Scale: Offensive Testing for Platforms

What happens when you test privacy controls at massive scale. Offensive privacy testing methodologies, the gaps most companies don't know they have, and what it takes to find them before regulators do.

For: Privacy Teams, Compliance, DPOs

How I Explain Things

Your CEO and your SOC analyst should both walk away understanding exactly what happened and what to do about it. That only works if you can tell the story right.

How I explain it

Your company has an internal system that hands out temporary passes to employees so they can access different services. We asked for one of those passes, took it home, and figured out the password it was based on. That password belonged to an account with the keys to the entire building. We used it to make a copy of every employee's credentials in the company. The fix is straightforward: stronger passwords on service accounts and disabling the outdated encryption that made the pass easy to crack.
