Modern digital supply chains are increasingly complex and vulnerable. In this episode of Security Matters, host David Puner is joined by Retsef Levi, professor of operations management at the MIT Sloan School of Management, to explore how organizations can “sense the signals” of hidden risks lurking within their software supply chains, from open source dependencies to third-party integrations and AI-driven automation.

Professor Levi, a leading expert in cyber resilience and complex systems, explains why traditional prevention isn’t enough and how attackers exploit unseen pathways to infiltrate even the most secure enterprises. The conversation covers the critical need for transparency, continuous monitoring, and rapid detection and recovery in an era where software is built from countless unknown components.

Key topics include:

• How to sense early warning signs of supply chain attacks
• The role of AI and automation in both risk and defense
• Best practices for mapping and securing your digital ecosystem
• Why resilience—not just prevention—must be at the core of your security strategy

Whether you’re a CISO, IT leader or security practitioner, this episode will help you rethink your approach to digital supply chain risk and prepare your organization for what’s next.

In this episode of Security Matters, host David Puner speaks with Andy Parsons, CyberArk’s Director of EMEA Financial Services and Insurance, whose career spans from the British Army to CISO and CTO roles in global financial institutions. Andy shares hard-earned lessons on leadership, risk management, and the evolving cybersecurity landscape in banking—from insider threats to machine identity governance and the rise of agentic AI.

Discover why “you can’t secure what you can’t see,” how manual processes fail at scale, and why treating machine identities as “first-class citizens” is no longer optional. Andy also explores the privileged access paradox, dynamic access management, and how AI is reshaping compliance, trading, and operational resilience.

Whether you're a security leader, technologist, or financial executive, this episode offers strategic insights and practical steps to future-proof your organization in an era of accelerating digital risk.

In this episode of Security Matters, host David Puner sits down with Matt Barker, CyberArk’s VP and Global Head of Workload Identity Architecture, for a deep dive into the exploding world of machine identities and the urgent need to rethink how to secure them. From his journey co-founding Jetstack and creating Cert Manager to leading CyberArk’s efforts in workload identity, Matt shares insights on why secrets-based security is no longer sustainable—and how open standards like SPIFFE are reshaping the future of cloud-native and AI-driven environments.

Discover how machine identities now outnumber humans 80 to 1, why leaked secrets are a "hacker’s buffet," and how workload identity is becoming a cornerstone of Zero Trust architecture. Whether you're a CISO, platform engineer, or just curious about the next frontier in cybersecurity, this episode offers actionable advice and a compelling vision for securing the age of AI agents.
