Welcome to Episode 31 of The Defender’s Journal.

This week, we’re joined by Matt Presson - a product-driven, context-obsessed security leader currently serving as CISO (Americas) at Bullish. From code reviews at FedEx to building global security functions across EY, B1, and now a regulated digital asset firm, Matt has seen cybersecurity from every angle.

We explore the three defining questions behind his leadership style: Why is context so important and can it mislead you? How do you embed security without creating resentment? And... what changes when you stop trying to do it all yourself?

Welcome to Episode 30 of The Defender’s Journal. 

This week, we sit down with Cezary Piekarski - a global cybersecurity leader with decades of experience across the financial sector, national advisory roles, and the highest levels of organisational leadership!

In this conversation, Cezary unpacks the three steepest climbs in his leadership journey = from managing a team for the first time, to leading leaders, to becoming accountable for a distinct security domain.

Welcome to a special spin-off episode of The Defender’s Journal.

This week, we sit down with Meg Anderson - a longtime security executive whose career spans nearly 40 years in one of the most tightly regulated environments in the industry...

We explore what longevity really takes, how leadership evolves over decades, and what she might need to unlearn if she swapped it all tomorrow for a disruptive, fast-moving startup. Meg also reflects on legacy, burnout, and the unseen patterns that define great CISOs - whether their name is on the resume or not!

Welcome to a bonus episode of The Defender’s Journal.

This week, we welcome back Ted Harrington - ethical hacker, author, and co-founder of IoT Village - to explore the mindset behind his new book "The Inner Hacker".

We dig into what hacker thinking really means (even in a world of audits, regulation, and surface-level compliance). Ted shares how to spot opportunities others miss and explains why minimum standards are dangerous. We also explore how cultural contexts can shape (or resist) innovation - and how any leader, technical or not, can start “hacking” their own blind spots today...
