How should security teams respond when identity sprawl starts driving negative productivity?

Why This Matters for Security Teams

Identity sprawl stops being a hygiene issue once the overhead of issuing, reviewing, rotating, and revoking access begins to outrun the team’s ability to govern it. At that point, productivity drops because every new directory, policy layer, and automation tool adds another place where access must be reconciled. NHI Management Group’s Ultimate Guide to NHIs notes that NHIs outnumber human identities by 25x to 50x in modern enterprises, which is why duplication can scale into operational drag very quickly.

This is not solved by adding more manual review. The better framing is architectural: reduce duplicate control planes, centralize authority where possible, and align governance to the systems that actually create access. That matches the direction of the NIST Cybersecurity Framework 2.0, which emphasises repeatable risk management over ad hoc process accumulation. In practice, many security teams encounter negative productivity only after auditors, incident responders, and platform teams are already compensating for overlapping identity tools.

How It Works in Practice

The first step is inventorying where identity decisions are being made. In sprawl-heavy environments, that usually includes human directories, cloud IAM, PAM, CI/CD credential stores, device management tools, and policy engines that each claim a slice of authority. Map those overlaps by asking three questions: who issues the identity, who approves the access, and who can revoke it. When the answers differ across platforms, the environment has likely accumulated avoidable complexity.

From there, teams should collapse the highest-friction duplicates first. A common pattern is to keep one authoritative directory for workforce identity, one workload identity system for services and agents, and one policy layer for request-time authorization. For non-human identities, the operational goal is to reduce static secrets and move toward short-lived credentials, because long-lived keys create more review burden than security value. The Ultimate Guide to NHIs — Key Challenges and Risks highlights how excessive privilege and weak visibility compound this problem.

• Consolidate duplicate approval paths so one policy engine governs the same class of access.
• Use one source of truth for inventory, even if multiple tools still enforce controls.
• Rotate and revoke credentials from the system that can actually prove ownership of the identity.
• Remove shadow workflows in ticketing, scripts, and CI/CD jobs that bypass governance.

For implementation guidance, teams should look for policy-as-code patterns that support consistent evaluation at request time, as well as Zero Trust principles that avoid implicit trust in any single control plane. The NIST Cybersecurity Framework 2.0 is useful here because it pushes teams to measure whether controls reduce risk, not just whether they exist. These controls tend to break down when identity tooling is embedded in legacy application release processes, because revocation and policy changes then depend on release cadence instead of security need.

Common Variations and Edge Cases

Tighter consolidation often increases migration effort, requiring organisations to balance reduced governance drag against short-term disruption. That tradeoff is real in M&A environments, regulated sectors, and hybrid estates where a single identity plane is not immediately feasible. Current guidance suggests prioritizing the identities that create the most operational load first, especially service accounts, API keys, and machine identities that are difficult to audit at scale.

There is no universal standard for how many identity systems is “too many,” so the practical test is whether each additional platform adds unique control value or just another review queue. When the answer is duplication, negative productivity usually shows up as delayed access approvals, broken offboarding, and more time spent reconciling logs than reducing risk. For that reason, the priority should be simplification with governance continuity, not simplification for its own sake. The broader market evidence in the The NHI and Secrets Risk Report shows how quickly unmanaged identities scale beyond manual oversight.
