・Lecture Summary Certificate lifecycles are tightening, device deployment is accelerating, and AI-driven systems are emerging inside every organization. These shifts are placing new demands on identity infrastructure that legacy PKI and certificate management tools were not designed to address. This session introduces a practical approach to modernizing identity across certificates, connected devices, and Agentic AI. We will discuss current industry pressures — including the operational impact of shorter certificate validity — and how organizations can meet increasing demand through automation, scalable architectures, and zero-trust principles. Attendees will learn how to strengthen operational resilience, reduce identity-related risk, and prepare for the next decade of security challenges.
