The rapid rise of AI agents—Agentic AI—has created a hidden identity problem for enterprises. Each AI agent needs a non-human identity (NHI) to authenticate with systems, and scaling from one to hundreds of agents introduces significant security and operational complexity.

Key insights:

• One Agent, One Identity Isn’t Simple: Even a single AI agent requires authentication. Most AI platforms still rely on static API keys, which are hard to rotate and easy to misuse.

• Non-Human Identity Systems Are Critical: Production-ready NHI solutions create unique identities with audit trails, cryptographic security, and permission controls, reducing risk compared to shared API keys.

• Monitoring AI Agents Adds More Identities: Synthetic monitoring and real-time quality checks require additional agent identities. Hundreds of AI agents can quickly multiply into thousands of identities, each needing governance.

• Risk Scales with Complexity: More identities mean more attack surfaces, compliance requirements, and management overhead. Enterprises must plan for lifecycle management, auditing, and access controls for every NHI.

Bottom line: The power of AI agents comes with hidden complexity. To secure, monitor, and manage AI deployments effectively, organizations must treat every agent as a first-class non-human identity, with robust governance and security controls.
