In a recent interview, Walmart’s CISO, Jerry R. Geisler III, shared four critical lessons for enterprise AI security: addressing the novel threats posed by autonomous (agentic) AI; redesigning identity and access systems with a start‑from‑scratch, Zero Trust mindset; achieving “velocity with governance” to speed AI innovation while maintaining rigorous oversight; and deploying AI‑vs‑AI defense strategies to identify and mitigate threats in real time

Key Takeaways
– Walmart emphasizes securing agentic AI, recognizing new attack vectors like autonomous misuse and cross-agent collusion.
– The company reboots identity access via modern protocols (MCP/A2A) within a Zero Trust framework and a startup-mindset re-architecture.
– “Velocity with governance” and AI-vs-AI defense reflect Walmart’s drive to accelerate AI deployment responsibly, embedding security into innovation cycles.
In-Depth
Walmart’s approach to AI security is smart and grounded—built not around hype, but around real, evolving risks. First, they’re taking on agentic AI head-on. These systems operate on their own and can do things we never explicitly told them to—but that also makes them unpredictable. So Walmart’s laying down fresh defenses that go beyond the old rules.
Second, they’re rebooting identity access like a startup would—scrapping decades of complexity to build from scratch. With modern protocols like MCP and A2A, they insist that every agent, tool, or request prove it belongs where it is before it gains access. That’s classic “never trust, always verify.” It’s Zero Trust, but shaped by today’s needs, not yesterday’s infrastructure.
Third, they’ve coined a great phrase: “velocity with governance.” The goal? Move fast on AI deployment without sacrificing oversight. That balance is often tricky, but Walmart’s determined to embed compliance, trust, and risk management into every step—so innovation doesn’t outpace control.
Finally, Walmart is exploring AI-vs-AI defense: letting AI fight AI. By using AI to spot and neutralize threats in real time, they’re effectively turning the tables on attackers. It’s forward-looking, and it scales in ways humans alone can’t keep up with.
In all, Walmart’s playbook is cool headed: proactive with agentic risks, rebuilding identity cleanly, accelerating smartly, and innovating defensively. It’s not flashy, but it’s effective—and that’s conservation of resources in action.
