TL;DR: AI is simultaneously improving identity detection, access decisions, and lifecycle automation while expanding the attack surface through AI agents, over-broad permissions, and weak attribution, according to Veza. Existing IAM models were built for human-speed access and now struggle to govern machine-speed identities with wider blast radius.
Editorial analysis by NHI Mgmt Group, based on content published by Veza: “How AI Is Reshaping Identity Security: Opportunities and New Threats”.
By the numbers:
- In the 2025 Verizon DBIR, over 30% of reported breaches involved misuse of non-human or AI agent credentials.
- In most organisations, machine identities outnumber humans over 20:1.
- In large organisations, the ratio of machine identities to humans can reach 45:1.
Key questions
Q: How should IAM teams govern AI agent access differently from human developer access?
A: IAM teams should govern AI agents as runtime consumers of access, not as users with durable credentials.
Q: Why do AI agents make least privilege harder to enforce?
A: AI agents can move across multiple services, make autonomous decisions, and trigger several machine-to-machine actions in one task.
Q: When does AI agent access become a governance risk instead of an automation benefit?
A: AI agent access becomes a governance risk when the agent can act beyond a single task, reuse credentials, or reach systems that were never explicitly approved for that workflow.
Practitioner guidance
- Map AI agent identities before deployment Inventory every AI tool, assistant and agent, then document the permissions each one inherits across cloud, SaaS, data and on-premises systems.
- Right-size permissions at the data layer Move beyond system-level grants by tying access boundaries to data classifications, sensitive repositories and actual usage patterns.
- Separate agent accountability from user attribution Record which agent acted, which human initiated it, what authority was delegated and what downstream systems were touched.
Bottom line: AI agents are changing identity security from a review problem into a runtime governance problem.

AI agents turn access governance into runtime governance: Identity models that assume access can be granted, reviewed and certified on a human cadence no longer hold when an actor can execute at machine speed. The control problem shifts from reviewing entitlements after the fact to governing how permissions behave during execution. Practitioners should treat AI agents as identities whose behaviour can outpace traditional review loops.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should security teams prove who did what in AI systems?
A: Security teams should bind every meaningful AI action to a named identity, an authorization chain, and a timestamped record that survives audit review. The answer must be reconstructable from logs, not dependent on memory or manual explanation. Without that evidence chain, compliance will usually treat the action as untrusted and the deployment as incomplete.
