As the number of AI agents and non-human identities is set to surpass 45 billion by the end of 2025 — more than 12 times the global workforce — enterprises face an urgent need to modernize identity and access management (IAM). Traditional IAM models, built for static human roles, are no longer adequate for managing the ephemeral, autonomous, and non-deterministic behavior of AI agents, according to a recent analysis from the World Economic Forum and industry experts.
Unlike predictable applications, AI agents exhibit dynamic decision-making — performing tasks differently each time based on context and data. This unpredictability makes pre-assigned permissions impractical and risky. Experts argue that identity systems must evolve from deterministic to adaptive models, using real-time, just-in-time authorization to grant ultra-short-lived access tokens. These tokens should expire within seconds, enforcing least privilege at machine speed and minimizing potential security breaches.
Key principles for securing the AI identity ecosystem include:
-
Dynamic and automated identity lifecycle management: Agents should be provisioned, monitored, and retired automatically.
-
Zero-trust for agents: Every agent-to-agent interaction must be authenticated, authorized, and logged — eliminating implicit trust.
-
Dual persona verification: Systems must recognize both the agent’s and human’s roles in a transaction to prevent misuse.
-
Continuous auditability: Every action must leave a verifiable trail for compliance and incident response.
The report warns that the traditional IAM scaffolding will collapse if enterprises fail to adapt. The future of security lies in machine-speed governance, where automated identity control, contextual awareness, and telemetry-driven feedback loops define trust. As businesses unleash fleets of AI agents to drive innovation, extending zero-trust frameworks and adopting dynamic permissions will be essential to balancing speed, resilience, and accountability in the AI age.
