TL;DR: Traditional IAM does not fit AI agents because agents authenticate through tokens, MCP handshakes, and workload identity, then request tool-level authorization at runtime, according to Cakewalk. The governing assumption collapses because access can be delegated, evaluated, and retired inside a single task, not a quarterly review cycle.
Editorial analysis by NHI Mgmt Group, based on content published by Cakewalk: “Top 8 Identity and Access Management Tools for AI Agents in 2026”.
Key questions
Q: What breaks when AI agents are treated like standard human users?
A: You lose visibility into effective permissions, expected behaviour, and real blast radius.
Q: Why do AI agents need separate runtime authentication and authorisation controls?
A: Because agent governance answers who approved the agent and what it should do, while runtime controls decide whether the agent can actually act in a specific system.
Q: What are the signs that identity governance is failing across SaaS and AI agent environments?
A: Identity governance is failing when local accounts, service accounts, API keys, and OAuth grants exist outside the directory, especially if they have no owner, no expiry, or survive offboarding.
Practitioner guidance
- Audit delegation paths for agent actions Map where AI agents act on behalf of humans, which tools they call, and which systems record the delegation chain.
- Replace standing agent access with task-scoped policy Require runtime policy decisions for each tool call and bind credentials to a single task or objective.
- Inventory agent authentication methods Document every agent path that uses OAuth, MCP server handshakes, service tokens, or workload identity assertions so governance covers the real authentication surface instead of only the IdP.
Bottom line: AI agent IAM is not just a new product category, it is a governance reset that exposes how much traditional IAM depends on stable human roles.

Access review cadence is the wrong control plane for AI agents. Access reviews were designed for identities that persist long enough to be observed, certified, and recertified. That assumption fails when an agent can appear, obtain task-scoped access, and complete work inside one session. The implication is not just faster review, but a different governance object: runtime delegation rather than accumulated entitlement.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: Should organisations unify human IAM and AI agent governance?
A: If agents routinely act on behalf of people, separate systems create gaps in attribution, approval, and auditability. A unified model is easier to reason about when you need to prove who initiated an action, what the agent was allowed to do, and which policy controlled it across the full delegation chain.
