Ron Dilley
Field CISO, Reflex Security
I build cybersecurity programs and the systems they run on, then I pressure-test them until the results are defensible. I’m a CISSP, IANS Research Faculty, and I’ve led security at scale across complex enterprise environments (including CISO responsibility).
Over the last few years, a growing slice of my work has pulled into AI in and around security, not just “AI strategy”, but the real mechanics: how models fail, how teams misuse them, how agents go sideways, and how to put guardrails in place that actually hold. I build and evaluate AI-driven systems because if you can’t measure it, you’re just vibing in production.
Today I partner with CISOs and security teams to strengthen incident response readiness using AI-driven crisis simulations that deliver real-time adaptive scenarios, actionable after-action insights, and audit-ready reporting.
Focus areas:
- AI Security & GenAI Governance (risk, controls, safe adoption)/li>
- AI Red Teaming / Prompt Injection / Agent misuse scenarios (practical failure modes)/li>
- Deception + Detection Engineering + SecOps transformation/li>
- High-scale telemetry and analysis: parsing, correlation, visualization, and “make the signal show up” systems
If you want AI in security that survives contact with real operations, that’s my lane.
