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.

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.

Welcome to another special crossover episode of The Defender’s and Disruptor’s Journal!

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…

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.

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.

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”.

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...

Welcome to Episode 34 of The Defender’s Journal!

This week, George Totev joins us - a CISO who has spent over 20 years operating at the intersection of regulation, product and real-world risk, building and scaling security and compliance functions across organisations like Goldman Sachs, Visa and Atlassian...

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.

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…

Welcome to Episode 33 of The Defender’s Journal.

This week, Sandeep Poonen joins us. From establishing VMware’s cloud security and enterprise cyber risk functions from the ground up to leading global compliance, fraud risk platforms and board-level cyber strategy, his career spans scale, regulation and high-stakes accountability...

In this episode, we explore what was forged early in his journey - moving countries at 17 and building under pressure - and how that shaped his philosophy on integrity, resilience and leadership. We unpack what it really means to “bowl the last over,” why preparation matters more than bravado, and how trust is built not through perfection, but through accountability.
