TL;DR: AI is pushing identity security beyond human users, as enterprises now manage machine identities, AI agents, APIs, workloads, and service accounts that authenticate autonomously and expand the attack surface, according to BigID. The core shift is that governance must connect identity, activity, and data access, because static IAM controls were built for interactive human behaviour, not continuous machine execution.
Editorial analysis by NHI Mgmt Group, based on content published by BigID: “Human vs Non-Human Identity Security: Why AI Is Reshaping Identity Risk”.
Key questions
Q: How should security teams govern sensitive data used by AI systems?
A: Security teams should treat AI as a data consumer that needs policy boundaries, not just authentication.
Q: Why do service accounts and AI agents need different controls from human users?
A: Service accounts and AI agents authenticate and act without the predictable patterns that human identity systems expect.
Q: What are the signs that machine identity governance is no longer keeping up?
A: Common signs include surprise certificate expirations, repeated manual renewals, inconsistent policy enforcement, and teams that cannot answer who owns a given key or trust anchor.
Practitioner guidance
- Define a machine-identity inventory Catalogue service accounts, API keys, workloads, bots, and AI agents as governed identities, with owners, purpose, and expiry conditions.
- Map AI workflows to data access paths Trace which AI agents and automation flows can reach sensitive data, which credentials they use, and which systems they can trigger.
- Reduce inherited machine privilege Review service accounts and workflow credentials for permissions that exceed the minimum needed for each task or integration.
Bottom line: AI-driven systems have pushed identity governance beyond human users and into machine identities that act continuously and at scale.

Human-centric identity governance is no longer a complete operating model. BigID’s central argument is that identity programmes built for people cannot fully govern systems that authenticate automatically, act continuously, and scale by design. The old model assumes access is tied to a human session and can be understood through login behaviour. That assumption no longer holds once workloads, APIs, and AI agents become primary actors in the access chain. Practitioners should treat machine execution as a distinct governance plane, not as a human user with a different label.
A few things that frame the scale:
- 43% of security professionals are concerned about AI systems learning and reproducing sensitive information patterns from codebases, according to the State of Secrets in AppSec.
- 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: What should organisations do when identity reviews do not cover AI workflows?
A: They should extend reviews to the workflows themselves, not just the underlying accounts. That means checking which AI systems are using which credentials, what data they can reach, and whether their access still matches the intended business process. Human-style recertification alone is not enough for autonomous machine access.
