Zero Trust for AI Agents: Why Separate Identity Alone Is Not Enough
Denis Korbakov, CTO of Smart-Soft, explains why traditional IAM approaches fail to secure autonomous AI agents that dynamically select tools, change context, and delegate authority. Only 21.9% of teams treat agents as distinct identity-bearing entities, while 45.6% rely on shared API keys and 44.4% use generic tokens. Research from Gravitee, Cloud Security Alliance, and Aembit shows that 68% of organizations cannot distinguish AI agent actions from human actions, 74% grant excessive privileges, and 52% allow rights inheritance. The article maps NIST SP 800-207 Zero Trust principles—explicit verification, least privilege, and assume breach—to agent workloads using short-lived scoped tokens, SPIFFE/SPIRE credentials, and layered policy enforcement points. A concrete ticket-diagnosis scenario illustrates how prompt injection can be contained through per-task authorization, dedicated network segments, and independent telemetry from NGFW and SIEM. The piece concludes with an open question on sub-agent delegation chains and offers reference OPA/Rego policies plus runbooks for pilot implementations.
