The Math Doesn’t Math: Why Cybersecurity Is Broken | Theresa Payton

Episode Notes

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:

• Why the current cybersecurity model is fundamentally broken—and what needs to change
• The growing gap between security spending and real-world outcomes
• How AI is reshaping the threat landscape as both a powerful tool and a potential insider risk
• Why designing for the human user—not just the buyer—is key to better security
• The overlooked importance of data classification in a post-quantum future
• Practical ways teams can begin “reimagining” security, even with limited time and resources

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At its core, this episode is a call to action: to move beyond compliance, rethink outdated approaches, and build a more human-centered, resilient future for cybersecurity.
