Art Gilliland, Delinea
This discussion at Black Hat 2026 examines securing artificial intelligence, AI agents and evolving identity controls. Art Gilliland of Delinea, chief executive officer, discusses Delinea’s approach to protecting sensitive assets as AI agents become operational actors. Krista Case of theCUBE Research, principal analyst and practice lead for cyber resilience and security, hosts the conversation covering agent behavior, differences between human and machine identities, just-in-time credentialing and the need for in-path authorization to preserve productivity while maintaining controls. Gilliland emphasizes that traditional identity and privileged access models must evolve for autonomous AI and that runtime just-in-time authorization should govern actions rather than static access. They stress differentiating agent versus human interaction, protecting critical assets and logging every call for auditability. Case underscores theCUBE Research finding of a confidence paradox in which organizations report high readiness despite limited agent controls, and they highlight the practical steps security teams can take to improve identity governance and runtime authorization for AI agents.
