Recorded live at RSA Conference 2026, this episode of The Segment features a compelling conversation between host Raghu Nandakumara and Theresa Payton—the first female White House Chief Information Officer and a leading voice on cybersecurity, AI, and digital risk. They tackle a critical question: If organizations are spending more than ever on cybersecurity, why are outcomes getting worse? Drawing from her experience protecting some of the most sensitive systems in the world, Theresa challenges conventional thinking around security frameworks, compliance, and the industry’s overreliance on checklists. The conversation dives into: human user Theresa also shares behind-the-scenes insights from her time at the White House, including a surprising story that highlights just how personal—and nuanced—cybersecurity can be. At its core, this episode is a call to action: to move beyond compliance, rethink outdated approaches, and build a more human-centered, resilient future for cybersecurity.

Social engineering attacks may evolve with new technology, but the core tactic hasn’t changed in decades: exploiting human trust. In this episode of The Segment, host Raghu Nandakumara sits down with Timothy Kromphardt, Senior Threat Researcher at Proofpoint to explore how modern scams actually work behind the scenes. Tim spends his days engaging directly with threat actors—sometimes for months at a time—to understand how fraud campaigns operate, how scammers build trust, and how they ultimately convince victims to hand over money or sensitive information. Together, they unpack the mechanics of today’s most common scams, including TOAD (telephone-oriented attack delivery) attacks, business email compromise, and the increasingly sophisticated “pig butchering” investment scams that can drain victims’ life savings after months of relationship-building. Together, Raghu and Tim unpack: If you’ve ever wondered how scammers actually operate—or why even highly successful professionals sometimes fall victim—this episode offers a rare inside look at the human side of cybercrime.

As a zero trust thought leader, co-lead of the Cloud Security Alliance Zero Trust Working Group, and author of Agentic AI + Zero Trust, Josh shares why AI isn’t just another tools-led transformation—it’s a fundamental re-engineering of how work gets done. Together, Raghu and Josh unpack: If you’re a business leader, technologist, or security professional grappling with how to move fast on AI without breaking trust, this episode offers a clear, practical, and grounded roadmap for doing AI right—securely, responsibly, and at scale.

What separates organizations that pass audits from those that survive real incidents? In this episode of The Segment, host Raghu Nandakumara sits down with Phil Park, global cybersecurity and risk leader at IBM. With more than 25 years advising financial institutions across the U.S., Europe, and Asia-Pacific, Phil brings a practical perspective on how supervision is rapidly evolving from compliance checklists to real-world operational readiness. Together, Raghu and Phil unpack the industry’s biggest mindset shift: regulators no longer ask “Are you protected?” — they ask “Can you operate through disruption?” They explore why prevention alone is no longer enough, why containment and recovery now define security maturity, and how CISOs are moving from siloed operators to enterprise-wide risk leaders accountable to boards and regulators alike. The conversation also dives into: This episode is a must-listen for security leaders and executives navigating a world where passing the audit is no longer the goal — proving you can withstand disruption is.
