What should organisations prioritise first in identity governance?

Organisations should prioritise the highest-cost access problems first: orphaned accounts, excessive privilege, and manual review bottlenecks. Those issues generate both breach risk and operating cost. Start where access cannot be explained cleanly, because unexplained access is usually where governance work, audit delay, and incident scope expand fastest.

Why This Matters for Security Teams

Identity governance gets expensive fastest where access is hard to explain: orphaned accounts, privileged service identities, stale secrets, and manual approvals that never keep pace with change. That is why the first priority is not broad policy redesign, but removing the access conditions that create unknown exposure and audit friction. NHI Management Group’s Ultimate Guide to NHIs notes that 97% of NHIs carry excessive privileges, and 80% of identity breaches involved compromised non-human identities such as service accounts and API keys.

Those numbers matter because governance failures compound. Once excessive privilege and poor lifecycle controls are present, reviewers spend time validating exceptions instead of reducing risk. The right starting point is the set of identities that can already move data, call APIs, or bypass normal approval paths. That aligns with the NIST Cybersecurity Framework 2.0’s emphasis on asset visibility, access control, and continuous risk management, rather than one-time access cleanup. In practice, many security teams encounter the real blast radius only after an audit, outage, or secrets leak has already exposed how much access was never fully owned or reviewed.

How It Works in Practice

Effective identity governance starts with a triage model. First, inventory every identity type, then rank them by business reach, privilege, and turnover. Human users matter, but non-human identities usually deserve earlier treatment because they scale faster, rotate less predictably, and are easier to overlook. The most actionable first wave is usually orphaned accounts, privileged service accounts, long-lived API keys, and access paths that depend on manual review queues.

From there, teams should reduce governance load by focusing on controls that shorten exposure windows and clarify ownership:

• Assign each identity to a named system owner and business purpose.
• Remove unused and duplicate access before tuning approval workflows.
• Replace standing privilege with just-in-time access where feasible.
• Rotate secrets on a schedule tied to risk, not convenience.
• Use policy-as-code and automated evidence collection to cut manual review bottlenecks.

For NHIs, the lifecycle view in Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs is especially useful because it frames onboarding, rotation, and offboarding as operational controls, not periodic paperwork. NIST guidance also supports this sequencing: govern the identities that can create the largest operational and security impact first, then expand coverage once ownership and visibility are in place. Organisations that do this well usually pair access review with monitoring so they can verify whether high-risk identities are actually used as expected. These controls tend to break down in environments with many ephemeral workloads and unmanaged third-party integrations because ownership and access drift faster than review cycles.

Common Variations and Edge Cases

Tighter identity governance often increases operational overhead at first, requiring organisations to balance risk reduction against delivery speed and support burden. That tradeoff is real, especially where engineering teams rely on shared automation accounts, legacy batch jobs, or third-party OAuth connections.

The first priority is not always the same control in every environment. Current guidance suggests choosing the highest-cost access problem first: if secrets are leaking in code, fix secret handling before expanding certification campaigns; if service accounts are over-privileged, reduce standing access before adding more approvals. For third-party access, NHI Management Group’s The State of Non-Human Identity Security shows how visibility gaps can hide risk, which means governance cannot rely only on annual reviews.

There is no universal standard for this yet, but best practice is evolving toward prioritisation by exposure, not by org chart. That means choosing identities with the widest blast radius, the weakest ownership, and the least reliable rotation first. Teams that start with low-risk user access often improve paperwork without materially reducing breach likelihood.
