How should executives evaluate identity security investments alongside other security priorities?

How Executives Should Compare Identity Security to Other Priorities

identity security investments should be judged on how much risk they remove from the organisation’s most exposed access paths, not on whether they are labelled as “identity” work. For executives, the useful question is which controls reduce likely compromise, limit blast radius, and improve recovery without creating disproportionate operational drag. NHIMG research shows that only 1.5 out of 10 organisations are highly confident in their ability to secure non-human identities, which is a strong signal that confidence often lags exposure.

That matters because identity is usually the control plane behind many other priorities: cloud security, third-party access, ransomware resilience, and AI workload governance all depend on it. A board-level investment case should compare identity programs against other security spend using the same lens: risk reduction, business enablement, implementation effort, and measurable outcomes. If identity work does not materially change the organisation’s ability to prevent misuse, detect abnormal access, or revoke access quickly, it should not be ranked ahead of more urgent gaps. The reverse is also true: when identity is the path that connects multiple systems, it often deserves priority over point fixes elsewhere. In practice, many executives discover the importance of identity only after access sprawl has already widened the impact of another security failure.

What Good Investment Decisions Look Like in Practice

Strong identity investment decisions start by mapping controls to the access relationships that create the most business exposure. That usually means understanding which identities can reach production systems, customer data, admin consoles, code pipelines, or AI tooling, and how quickly those privileges can be changed when risk appears. If an identity control shortens credential lifetime, narrows privilege, or improves detection and revocation, it often produces more durable risk reduction than another layer of perimeter tooling.

Executives should also compare identity spend against the organisation’s operating model. Some controls are low-friction and high-value because they reduce risk without slowing delivery, while others are effective but expensive to run at scale. The right investment framework asks whether the control can be adopted consistently across human and non-human identities, whether it is visible to audit and incident response, and whether it closes a gap that attackers can realistically exploit. For example, credential rotation, access review, and visibility into third-party or service-account connections usually matter more than abstract policy statements because they change the actual attack surface.

• Prioritise controls that reduce standing privilege and improve revocation speed.
• Score each investment by how many high-value systems it affects, not just by technical elegance.
• Measure whether the control improves visibility, not only whether it was deployed.
• Prefer spend that creates repeatable governance outcomes across environments.

For executive comparison, the most useful benchmark is whether the investment changes the organisation’s ability to contain misuse before it becomes material. Current guidance suggests that controls should be selected for observable risk reduction, not for the size of the technology category they belong to. The U.S. NIST control catalogue is useful here because it frames identity-related safeguards as operating controls rather than abstract security aspirations.

These controls tend to break down when identity ownership is unclear across cloud, engineering, and third-party teams because no one can reliably enforce the access changes the budget assumes.

Where Identity Spend Is Usually Underestimated

Tighter identity control often increases operational overhead, so organisations have to balance faster delivery against stronger access governance. That tradeoff is especially visible in environments with many service accounts, API keys, and automated workflows, where manual review alone does not scale.

One common mistake is funding a visible control initiative while leaving lifecycle management, monitoring, and offboarding weak. Another is treating human and non-human identity as separate budget conversations when the same failure patterns often apply to both. Identity security is also easy to underfund when the value is measured only in incidents avoided, because the benefit shows up as reduced blast radius, less incident time, and cleaner compliance evidence rather than a single headline win. Executives should therefore ask for outcome metrics such as fewer long-lived credentials, better coverage of privileged identities, and faster containment when access must be revoked.

Practitioner Guidance: Prioritise the identity investments that most clearly reduce standing access to critical systems, especially where credentials, third parties, or automation can amplify impact.

Decision rule: If an identity control does not measurably improve revocation speed, privilege reduction, or visibility, treat it as lower priority than controls that do.

What to verify: Confirm that the budgeted control covers both human and non-human identities, because many of the highest-impact access paths now sit in automation and service-to-service connections.

What good looks like: Executives can point to a smaller set of over-privileged identities, shorter credential lifetimes, and clearer reporting on who or what can reach the most sensitive assets.

Practitioner takeaway: Identity security deserves priority when it changes the organisation’s real attack surface, not merely when it improves policy posture or technical neatness.
