The Segment

AI is moving faster than any technology shift we’ve seen before—but security is still being treated as an afterthought. In this episode of The Segment, host Raghu Nandakumara sits down with Joshua Woodruff, Founder & CEO of Massive Scale AI, to explore what it really takes to adopt AI, especially agentic AI, without putting your business at risk. Josh brings nearly 30 years of experience across security, cloud, and IT transformation, advising organizations from startups to Fortune 100 enterprises. 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.
