They should prioritise it before broad deployment, because the first wave of AI usage often creates the largest blind spots. If the identity model, approval path, and review cadence are not defined early, the organisation inherits shadow usage and excess access that are harder to unwind later. Governance should precede scale.
Why This Matters for Security Teams
For agentic AI, the decision point is not whether an AI system is useful, but whether its identity, authority, and revocation model exist before it touches production. That matters because autonomous tools do not behave like static applications: they can chain actions, call other services, and expand their footprint faster than manual review can keep up. Current guidance increasingly points to identity-first governance as the safer default, especially when teams are still defining workload identity, NIST Cybersecurity Framework 2.0, and the control boundaries of agentic systems.
NHIMG research shows the scale of the risk: in the 2026 Infrastructure Identity Survey, 70% of organisations grant AI systems more access than a human doing the same job, while only 44% have any policies for managing AI agents. That gap is exactly why governance should precede rollout, not follow it. Without early guardrails, teams discover over-privilege after the first incident, not during design.
In practice, many security teams encounter the identity problem only after AI has already been given standing access, rather than through intentional governance design.
How It Works in Practice
Prioritising AI identity governance means defining who or what the agent is, what it may do, and under which conditions it may do it before deployment expands. For autonomous systems, static RBAC alone is usually too blunt because an agent’s actions are task-driven and context-dependent. A better pattern is workload identity plus real-time authorisation, where the agent proves its identity cryptographically and receives only the minimum access needed for the current task. That is consistent with emerging guidance in NIST Cyber AI Profile (IR 8596) and with the lifecycle and governance principles described in the Ultimate Guide to NHIs.
In operational terms, security teams should align approvals, policy, and telemetry around the agent’s task boundary rather than the deployment date. That usually includes:
- Issuing short-lived, task-scoped credentials through JIT workflows instead of embedding static secrets in pipelines or code.
- Using workload identity as the primary trust anchor, so the system can authenticate the agent, not just a token it presents.
- Applying intent-based or context-aware authorisation at runtime, so policy is evaluated against the requested action, target resource, and risk context.
- Setting explicit review cadences for permissions, because autonomous tools can drift from their original use case quickly.
- Logging every privileged action with enough context to support incident response and audit.
The case for doing this early is reinforced by NHIMG data: only 5.7% of organisations have full visibility into service accounts, and 79% have experienced secrets leaks. Those figures make it clear that weak identity hygiene is not a theoretical weakness; it is the normal failure mode. These controls tend to break down when agents are allowed to act across multiple toolchains with shared credentials because attribution, revocation, and blast-radius containment all become harder at once.
Common Variations and Edge Cases
Tighter AI identity governance often increases delivery overhead, requiring organisations to balance deployment speed against the risk of uncontrolled privilege. That tradeoff is real, especially in environments where product teams want rapid experimentation, but current best practice is evolving toward short-lived access and policy-as-code rather than broad standing access. There is no universal standard for this yet, which is why many organisations use NIST Cybersecurity Framework 2.0 for governance structure and the Ultimate Guide to NHIs — Regulatory and Audit Perspectives for audit-friendly control design.
Edge cases appear when agents are embedded in customer-facing workflows, multi-agent pipelines, or infrastructure automation. In those settings, one agent may hold a valid task token while another needs to inherit or request access, and that handoff must be governed explicitly. The most reliable approach is to define separate identities for separate functions, avoid credential reuse, and treat each handoff as a new authorisation event. For deeper identity risk patterns, the 52 NHI Breaches Analysis and the Top 10 NHI Issues show how quickly unchecked access turns into exposure.
Where organisations defer governance until after deployment, they often end up retrofitting controls around already-expanded access paths, which is slower, noisier, and more expensive than setting the model first.
