In this episode of Security Matters, host David Puner welcomes back David Higgins, senior director in CyberArk’s Field Technology Office, for a timely conversation about the evolving cyber threat landscape. Higgins explains why today’s attackers aren’t breaking in—they’re logging in—using stolen credentials, AI-powered social engineering, and deepfakes to bypass traditional defenses and exploit trust.

The discussion explores how the rise of AI is eroding critical thinking, making it easier for even seasoned professionals to fall for convincing scams. Higgins and Puner break down the dangers of instant answers, the importance of “never trust, always verify,” and why zero standing privilege is essential for defending against insider threats. They also tackle the risks of shadow AI, the growing challenge of misinformation, and how organizations can build a culture of vigilance without creating a climate of mistrust.

Whether you’re a security leader, IT professional, or just curious about the future of digital trust, this episode delivers actionable insights on identity security, cyber hygiene, and the basics that matter more than ever in 2026 and beyond.

As enterprises embrace agentic AI, a new security risk equation emerges. In this episode of Security Matters, host David Puner sits down with Lavi Lazarovitz, VP of Cyber Research at CyberArk Labs, to unpack how AI agents and identity security are reshaping the threat landscape. Learn why privileged access is now the fault line of enterprise security, how attackers exploit overprivileged AI agents, and what security teams must rethink before scaling AI. Packed with real-world examples and actionable insights, this is a must-listen for anyone meeting the challenges of AI and cybersecurity.

Eric O’Neill, former FBI ghost and author of “Spies, Lies & Cybercrime,” joins host David Puner to take a deep dive into the mindset and tactics needed to defend against today’s sophisticated cyber threats. Drawing on O’Neill’s experience catching spies and investigating cybercriminals, the conversation explains how thinking like an attacker can help organizations and individuals stay ahead. The episode covers actionable frameworks, real-world stories, and practical advice for building cyber resilience in an age of AI-driven scams and industrialized ransomware.

In this episode of Security Matters, host David Puner sits down with Yuval Moss, CyberArk’s VP of Solutions for Global Strategic Partners, to explore the fast-evolving world of agentic AI and its impact on enterprise security. From rogue AI agents deleting production databases to the ethical blind spots of autonomous systems, the conversation dives deep into how identity and Zero Trust principles must evolve to keep pace. Yuval shares insights from his 25-year cybersecurity journey, including why AI agents behave more like humans than machines—and why that’s both exciting and dangerous. Whether you're a security leader, technologist or curious listener, this episode offers practical guidance on managing AI agent identities, reducing risk, and preparing for the next wave of autonomous innovation.

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.
