Inspired by Phil Venables’ Good CISO / Bad CISO framework, this piece explores the mental models that distinguish effective security leaders from those trapped in reactive cycles.

I’ve spent the past decade working across cloud, application, and enterprise security. I currently serve as an Information Security Lead and Deputy CISO.

My work centers on advising executives on risk, resilience, and security strategy while ensuring that security aligns with broader business priorities.

Cyber threats aren’t just evolving — they’re outpacing traditional defenses at alarming speed.

From weak passwords protecting sensitive AI systems to phishing attacks that now bypass MFA, today’s adversaries are more creative, persistent, and unpredictable than ever.

To survive this landscape, frameworks alone won’t cut it. You need sharper thinking.

That’s where mental models come in — cognitive tools used by elite cybersecurity leaders, red teamers, and incident commanders to filter out noise, think clearly under pressure, and execute fast.
