Most security breakthroughs don't come from new technology, they come from finally getting the basics right. As AI accelerates both attacks and the pace of vulnerability disclosure, the organizations that fare best aren't the ones chasing the next big thing, but the ones with the visibility, governance, and segmentation to absorb the shock.
In this episode, Raghu Nandakumara sits down with Jason Garbis, founder and CEO of Number Line Security and co-chair of the Zero Trust Working Group at the Cloud Security Alliance, to explore what Zero Trust looks like when threats evolve at machine speed.
Jason draws on his path from early software-defined perimeter work to leading Zero Trust strategy at the Cloud Security Alliance, sharing why "right-sizing" a Zero Trust initiative matters more than chasing sweeping transformation, and why even a well-built security capability fails without genuine buy-in from the business.
The conversation then turns to AI's effect on the threat landscape: the surge of vulnerabilities and patches enterprises now have to absorb, the widening gap between attacker speed and defender response, and why segmentation remains one of the most effective ways to shrink the blast radius of an attack.
Raghu and Jason discuss:
How to right-size a Zero Trust initiative for an organization's actual readiness
Why "build it and they will come" doesn't work for security adoption
Tying Zero Trust investments to business priorities like AI adoption, M&A, and compliance
What's genuinely new — and what isn't — about securing AI systems and agents
How accelerating vulnerability disclosures are reshaping patch management
Why segmentation reduces blast radius even when patching can't keep pace
A simple analogy for explaining zero trust to non-security stakeholders
Jason closes with his go-to way of explaining Zero Trust to non-technical stakeholders: an analogy involving brakes, oil, and seat belts that reframes security as a shared responsibility rather than a roadblock.

AI is giving attackers new ways to move faster, scale attacks, and explore every possible path through an environment. But does that mean defenders need an entirely new security strategy? In this special episode of The Segment, Raghu Nandakumara is joined by John Kindervag, creator of Zero Trust and Chief Evangelist at Illumio; Rich Mogull, Chief Analyst at the Cloud Security Alliance; and Don Yeske, longtime federal cybersecurity leader and Senior Solutions Architect and Enablement Lead at Virtru, to celebrate the launch of their new book, Cyber Resilience at Machine Speed: The Zero Trust Model for the AI Era. Together, they explore why Zero Trust remains critical in the age of AI, how organizations can identify and secure their most important protect surfaces, and why trying to defend everything at once is often a recipe for failure.

AI may be the latest technology transformation, but for security teams, the challenges feel familiar. In this episode of The Segment, Raghu Nandakumara sits down with Ashish Rajan, CISO of TechRiot, host of the Cloud Security Podcast and AI Security Podcast, and author of AI Security Engineering, to explore what the cloud era can teach us about securing AI. They discuss how AI is reshaping cloud security, why the shared responsibility model gets even murkier with AI, and what changes when security teams have to protect agents whose behavior and intent aren’t always predictable. Ashish also shares how organizations can start building practical AI security programs today, why continuous evals and human oversight matter, and the AI skills security practitioners will need for what comes next. https://www.aisecuritypodcast.com/ https://www.cloudsecuritypodcast.tv/ https://www.amazon.com/dp/1394387687?lv=shuf&channelId=500&plpRedirect=mhFallback
