What should IAM teams prioritise first in a modern identity strategy?

Why This Matters for Security Teams

Modern identity strategy usually fails at the edges first: service accounts, API keys, workload tokens, and temporary access paths. Those are the identities that keep pipelines, cloud services, and automation running, so they are also the easiest place for exposure to spread. NHI Management Group’s Ultimate Guide to NHIs shows why this matters: NHIs outnumber human identities by 25x to 50x in modern enterprises, and 80% of identity breaches involved compromised non-human identities such as service accounts and API keys.

Security teams often focus first on directory cleanup or SSO polishing, but fragmented identity data makes every downstream control inconsistent. A strong foundation means the same identity can be traced across HR, directory, cloud, and SaaS systems, with lifecycle events governed centrally rather than by ad hoc exceptions. That baseline also supports higher-value controls such as entitlement review, offboarding, and temporary access expiry. The NIST Cybersecurity Framework 2.0 reinforces this sequencing by tying identity governance to broader protect and detect outcomes.

In practice, many security teams encounter identity sprawl only after a leaked credential, failed offboarding, or privilege review has already exposed the gap.

How It Works in Practice

The first priority is to establish a unified identity foundation that can answer three questions consistently: who or what the identity is, what it can access, and when that access should expire. For human identities, that usually means synchronising HR, directory, and SaaS records. For non-human identities, the same logic must extend to secrets managers, CI/CD systems, cloud IAM, and workload identity platforms. The operational goal is not just inventory, but authoritative linkage between identity, ownership, and lifecycle state.

Once that foundation exists, teams can automate the highest-risk lifecycle events. Offboarding should revoke access from human and non-human identities as a matter of policy, not manual ticketing. Temporary access should be time-bound by default, with just-in-time access for elevated tasks and automatic expiry. Entitlement discovery then becomes credible because the source data is cleaner and duplicates are reduced.

• Standardise identity sources of record before tuning access policies.
• Map service accounts, API keys, and workload identities to named owners.
• Automate termination, rotation, and expiry for the riskiest access paths first.
• Use inventory and classification to distinguish active identities from stale ones.

NHIMG research highlights the scale of the problem in The 2024 Non-Human Identity Security Report: 88.5% of organisations say their non-human IAM practices lag behind or are merely on par with human IAM, and only 19.6% express strong confidence in managing workload identities securely. That gap is why maturity starts with unified visibility, not with advanced policy logic. Current guidance suggests aligning this work with NIST CSF 2.0 identity outcomes, then hardening non-human lifecycle controls with the broader lessons documented in the Top 10 NHI Issues.

These controls tend to break down when identity ownership is split across business units and cloud teams because no single system can reliably revoke or attest to access state.

Common Variations and Edge Cases

Tighter identity control often increases operational overhead, requiring organisations to balance speed of delivery against stronger governance. That tradeoff is especially visible in cloud-native environments, where teams want rapid provisioning and short-lived credentials, but still need auditable ownership and consistent expiry rules.

There is no universal standard for this yet across every stack, so current guidance suggests prioritising the identities that create the highest blast radius. In practice, that usually means production service accounts, API keys embedded in automation, and external-facing integrations before lower-risk user entitlements. Hybrid and multi-cloud environments also complicate sequencing because access data may be duplicated across providers, making reconciliation as important as remediation. NHIMG’s 52 NHI Breaches Analysis is useful here because it shows how often one stale credential or excessive entitlement becomes a broader compromise path.

For organisations already deep into Zero Trust, the practical move is to treat identity consolidation as the prerequisite for policy enforcement, not the by-product of it. The biggest mistake is assuming access governance can be made consistent before identity data is consistent.
