TL;DR: Traditional IAM was designed for people, applications, and service accounts, but TruFoundry argues that AI agents, MCP tools, and autonomous workflows now need distinct identities, task-scoped authorization, and auditability. The core issue is that static roles and shared accounts do not map cleanly to runtime agent behaviour, especially when access is dynamic and action timing is machine-driven.
NHIMG editorial — based on content published by TruFoundry: What Is Identity and Access Management? A Complete Enterprise Guide for 2026
By the numbers:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
- Only 5.7% of organisations have full visibility into their service accounts.
- NHIs outnumber human identities by 25x to 50x in modern enterprises.
Questions worth separating out
Q: How should security teams govern AI agents that call APIs instead of using a UI?
A: Security teams should govern AI agents by treating each callable action as a scoped entitlement, not as a general application login.
Q: Why do shared service accounts create risk for AI agents?
A: Shared service accounts hide which agent made a request, so they collapse accountability and make incident response slower.
Q: What breaks when IAM is still designed around human lifecycle events?
A: It becomes misaligned with workloads that execute continuously or change permissions at runtime.
Practitioner guidance
- Assign unique identities to every AI agent Create separate identities, scopes, and lifecycle ownership for each agent instead of reusing shared service accounts across workflows.
- Scope permissions by task and tool Limit each agent to the minimum tool set required for the current workflow, and re-evaluate that scope whenever the agent’s use case changes.
- Log every agent action inside the environment Record identity, resource, action, policy outcome, and context for every invocation so audit teams can reconstruct the sequence without stitching together partial logs from different systems.
What's in the full article
TruFoundry's full guide covers the operational detail this post intentionally leaves for the source:
- Concrete examples of how to map IAM concepts to AI agents, service accounts, and machine identities in production environments.
- The specific access-control patterns used to enforce OAuth scoping, RBAC, and MCP controls before agent execution.
- Practical guidance on audit logging, lifecycle administration, and policy enforcement across AI workloads and enterprise systems.
- The article’s walkthrough of how to think about IAM architecture when human and non-human identities share the same environment.

AI agent governance collapses if IAM still assumes access is static. Traditional IAM programmes are built around identities that join, change role, and leave on a human timescale. AI agents can create and consume access across a single task window, which means static entitlement models do not describe the actual behaviour being governed. The implication is that identity governance has to move closer to runtime execution instead of relying on periodic review alone.
A few things that frame the scale:
- NHIs outnumber human identities by 25x to 50x in modern enterprises, according to Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which is why identity sprawl keeps outpacing governance.
A question worth separating out:
Q: Who is accountable when an AI agent acts outside its intended scope?
A: The organisation is accountable, but operational responsibility should sit with a named owner and a governance process that can explain the agent’s purpose, access, and recorded actions. Without that, autonomous behaviour becomes unassignable risk rather than managed automation.
