The Defender's Journal Episode 38 - Ashwin Mithra

Welcome to Episode 38 of The Defender’s Journal! This week, Ashwin Mithra joins us - Global Head of Information Security at CloudBees, where his team sits at the intersection of software delivery, cloud operations and AI-driven development at scale. In this episode, we explore why security can no longer survive as a checkpoint in the pipeline. Ashwin breaks down why developers route around friction, why “death by screenshot” governance doesn’t work when AI is shipping thousands of changes a day, and why the future of secure delivery depends on making security automatic, inherited and ambient - not something teams learn reluctantly at the end. + Interested in joining us on the show?

The Defender's Journal Episode 37 - Bashar Abouseido

Welcome to Episode 37 of The Defender’s Journal! This week, Bashar Abouseido joins us - President of Cybersecurity at TENEX.AI and former long-serving CISO at Charles Schwab, where cyber decisions carried consequences beyond systems and into markets, trust and business continuity… In this episode, we explore why the traditional security model of adding more analysts, more tools and more process has reached its limit. Bashar breaks down why “you can’t out-hire a machine”, why culture can eat your threat model, and why the next generation of security operations will be defined by AI-native scale, context engineering and human-led decision-making at machine speed. + Interested in joining us on the show?

The Defender's Journal Episode 36 - Kevin Fielder

Welcome to Episode 36 of The Defender’s Journal! This week, Kevin Fielder joins us - CISO at NatWest Boxed, operating at the intersection of embedded finance, cloud-native banking and real-world security trade-offs... In this episode, we explore what it takes to secure a banking platform that sits behind major consumer brands, why “yes, but safely” beats defaulting to no, and how AI is changing the way teams need to think about trust, verification and risk. Kevin also shares why great security leadership is rarely about fixing everything at once - it’s about understanding what matters most, and moving the business forward without losing control. + Interested in joining us on the show?

This week, Lee Rossey joins us - CTO and Co-Founder of SimSpace, a company helping organisations prove whether their teams, tools and AI agents can perform under real-world pressure. In this episode, we explore why cyber readiness can no longer rely on assumptions, vendor claims or controlled lab results. Lee breaks down the value of high-fidelity cyber ranges, AI proving grounds and digital twin-style environments - and why the future of security may depend on testing machine-speed responses before they ever reach production… + Want to be part of the journey?

A Defender's x Disruptor's Journal Crossover - Matt Moynahan

Welcome to another special crossover episode of The Defender’s and Disruptor’s Journal! This week, Matt Moynahan joins us - CEO of GetReal and a leader focused on one of the most urgent questions in security: what happens when identity itself can be fabricated in real time? In this episode, we explore why traditional security stacks were never designed for a world of synthetic media, deepfake detection and forensic verification. Matt breaks down where enterprise failures are already emerging - from candidate fraud and account takeover to executive impersonation - and why the next decade of security may depend on restoring trust to digital communication itself. + Want to be part of the journey?

A Defender's x Disruptor's Journal Crossover - Rick Caccia

Welcome to another special crossover episode of The Defender’s and Disruptors’ Journal. This week, Rick Caccia joins us - CEO of WitnessAI and former CMO at companies including Palo Alto Networks and Google Cloud. Having spent three decades shaping how major technology markets are understood, Rick is now building in one of the fastest-moving spaces of all: safe enterprise AI adoption. In this episode, we explore why most organisations are still struggling to understand how AI is really being used, why “blocking everything” creates a false sense of control, and how WitnessAI shifted from a fear-led security message to solving the far less glamorous - but far more urgent - problem of AI compliance, visibility and governance. + Want to be part of the journey?

The Defender's Journal Episode 35 - Omkhar Arasaratnam

Welcome to Episode 35 of The Defender’s Journal! This week, Omkhar Arasaratnam joins us - a Distinguished Engineer at LinkedIn whose career has taken him from factory work and DJ’ing to leading cyber and engineering functions across IBM, Deutsche Bank, Credit Suisse, JPMorgan and Google. In this episode, we explore why careers are rarely ladders, the difference between advisors and operators, and what changes when you build security into systems serving millions of users. Omkhar also reflects on analysis paralysis, mentorship, and the mindset that turns every day into a “bonus round”.

A Defender's x Disruptor's Journal Crossover - Damon Kachur

Welcome to another special crossover episode of The Defender’s and Disruptors’ Journal. Today’s guest is Damon Kachur , CEO of SecureG - a leader who has spent over two decades building the invisible infrastructure that digital trust depends on, from issuing billions of device identities to securing the networks behind telecom, IoT and critical systems. In this episode, we explore what it really means to build trust at scale - from the early days of PKI and stopping large-scale fraud, to the future of quantum-resistant cryptography and machine identity. Damon also shares his mindset as a leader under pressure, why trust infrastructure is still misunderstood at board level, and how the next wave of AI and connected systems will redefine identity entirely... + Want to be part of the journey?

The Defender's Journal Episode 34 - George Totev

Welcome to Episode 34 of The Defender’s Journal!

In this episode, we explore how security leaders should think about trade-offs at scale - from balancing prevention vs reaction, to understanding diminishing returns in security investment, and why incident management is ultimately the last line of defence. George also touches on how to communicate risk effectively to boards - not through theory, but through cost, consequence and real-world impact. + Interested in joining us on the show?

A Defender's x Disruptor's Journal Crossover - Abhi Sharma

Welcome to another crossover episode of The Defender’s Journal. Today’s guest is Abhi Sharma , co-founder and CEO of Relyance AI - a company rethinking how organisations secure data in the age of AI. Rather than treating data as something static, his team is building an AI-native approach to privacy, governance and security that focuses on the movement of data itself. In this episode, we explore how Abhi’s early experiences shaped his leadership philosophy, why “unreasonable hospitality” has become a defining cultural pillar at Relyance AI, and what many organisations still misunderstand about building trust in AI-driven systems… + Want to be part of the journey?
