Agentic AI systems act autonomously across enterprise environments, making traditional perimeter-based security ineffective. Zero Trust treats AI agents as independent actors with identities, enforcing continuous verification, least-privilege access, and contextual controls across APIs, systems, and data.

When done right, it enables organizations to scale autonomous AI safely—without sacrificing speed, innovation, or trust.
