Welcome to a special crossover episode between ‘The Defender’s Journal’ and our new sister series focussed on ‘The Disruptors’ where we shift the lens from what needs defending to what we’re building next...

Our guest is Harry Wetherald - a founder with one foot in venture capital, the other in technical scale. As co-founder and CEO of Maze, he’s raised over $30 million and is reimagining vulnerability management through an AI-native lens - building systems that anticipate, recommend, and act, rather than wait for direction.

We dig into the mindset behind Maze’s mission, and explore what marketing in cyber gets wrong, what AI-native actually means in practice, and why clarity is a more powerful moat than complexity!

Welcome to another hard-hitting spin-off of The Defender’s Journal.

Today’s guest is Ryan Lindley - CEO of Aegis Cyber and one of the industry’s clearest thinkers when it comes to security leadership. From crashing school networks as a teen hacker to rebuilding billion-dollar organisations post-breach, Ryan brings sharp insight, zero fluff, and hard-earned lessons to this conversation.

In this episode, we dive into what separates tactical firefighting from real security strategy - and what most companies still get wrong about cyber maturity. We also explore how Ryan’s Military Academy experience shaped his mindset, why influence beats authority, and why he refuses to work with organisations that won’t take fundamentals seriously.

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?
