How should organisations govern non-human identities across their environment?

Why This Matters for Security Teams

Governance fails when non-human identities are treated as background plumbing instead of accountable actors. Service accounts, API keys, certificates, and workload tokens often outnumber human users by a wide margin, so even a small control gap creates outsized exposure. NHI Mgmt Group research shows that 97% of NHIs carry excessive privileges, which turns routine drift into a standing access problem. The practical lesson is that ownership, purpose, and review cadence matter as much as the credential itself.

Security teams usually inherit fragmented ownership, hidden secrets, and inconsistent lifecycle practices. That is why the Top 10 NHI Issues and the Ultimate Guide to NHIs — Regulatory and Audit Perspectives are useful references for mapping governance to auditability, while NIST Cybersecurity Framework 2.0 helps teams anchor the work in asset management, access control, and continuous improvement. In practice, many security teams encounter NHI abuse only after a stale credential is used in a breach rather than through intentional review.

How It Works in Practice

Effective governance starts with a complete inventory of NHIs across code, CI/CD pipelines, cloud services, SaaS integrations, and runtime workloads. Each identity should have a human owner, a documented business purpose, and a defined expiry or review date. The operating model should also separate authentication from authorisation: authentication proves the workload is what it claims to be, while authorisation decides what it may do at that moment. For many organisations, the Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs is the clearest path from discovery to offboarding.

Best practice is to combine least privilege with time-bounded access. That means using PAM where elevated access is unavoidable, but preferring JIT issuance, short-lived secrets, and automated revocation over long-lived static credentials. Where modern platforms allow it, workload identity should replace shared secrets so the system can prove identity with cryptographic tokens rather than reusable passwords or keys. Guidance increasingly points to policy-as-code and continuous evaluation so access is decided at request time, not by a static role that was granted months ago.

• Inventory every NHI and classify it by workload, environment, and business service.
• Assign a human owner who can approve, review, and revoke access.
• Rotate or expire secrets on a fixed schedule, with immediate revocation on offboarding.
• Prefer workload identity and JIT credentials for services that support it.
• Review entitlements against actual usage and remove dormant privileges.

These controls tend to break down in legacy estates where shared service accounts, embedded credentials, and opaque third-party integrations make ownership and revocation difficult.

Common Variations and Edge Cases

Tighter governance often increases operational overhead, requiring organisations to balance stronger control with deployment speed and platform complexity. That tradeoff is especially visible in environments with many ephemeral workloads, multi-cloud pipelines, or vendor-managed integrations. There is no universal standard for this yet, but current guidance suggests treating short-lived runtime access differently from persistent administrative access.

For agentic systems and autonomous workloads, the problem becomes more dynamic because the identity may act in ways that are not fully predictable at design time. In those cases, static RBAC alone is often too blunt, because the agent’s task, context, and tool chain can change during execution. A more robust pattern is intent-based or context-aware authorisation, backed by real-time policy evaluation. The same principle appears in security research like the JetBrains GitHub plugin token exposure, where exposed tokens and over-permissioned access show how quickly a single secret can become a broad compromise path. For organisations formalising this work, NIST Cybersecurity Framework 2.0 and the NHI lifecycle guidance provide a practical baseline, but the best practice is still evolving for autonomous agents and multi-agent pipelines. In practice, the weakest point is usually not the policy model, but the first legacy system that cannot issue, scope, or revoke access cleanly.
