They often treat vendor count as the metric, when the real issue is whether authority is coherent. A smaller stack does not automatically mean better governance if service accounts, human admins, and secrets are still scattered across disconnected processes. The goal is fewer control gaps, not simply fewer contracts.
Why This Matters for Security Teams
Reducing vendor count can help, but only if it also reduces duplicated authority, inconsistent access paths, and unmanaged secrets. The common mistake is to equate consolidation with control, when the actual risk sits in how identities, approvals, and monitoring are distributed across the environment. A cleaner procurement picture can still hide fragmented service accounts, shadow integrations, and stale API keys.
That distinction matters because NHIs already outnumber human identities by 25x to 50x in modern enterprises, and the operational burden rises quickly when each vendor brings its own token model, log format, and privilege model. The NIST Cybersecurity Framework 2.0 emphasizes coherent governance across assets and access decisions, not just fewer tools in the stack. NHI Management Group’s research on Ultimate Guide to NHIs — The NHI Market shows why that matters: 97% of NHIs carry excessive privileges, and 71% are not rotated within recommended time frames.
In practice, many security teams discover vendor sprawl only after a token, service account, or third-party integration has already been abused rather than through intentional design review.
How It Works in Practice
The better question is not “How many vendors do we have?” but “How many distinct trust and control models are we running?” A smaller stack can still be unsafe if one platform handles scanning, another handles secrets, a third handles approvals, and none of them share a unified view of workload identity. For NHI governance, authority needs to be coherent across issuance, usage, rotation, and revocation.
Current guidance suggests mapping every security vendor to the control domain it actually owns. That means identifying whether it manages secrets, monitors access, enforces policy, or only reports on activity. The objective is to remove redundant controls, not to collapse everything into one console. The NIST Cybersecurity Framework 2.0 is useful here because it pushes organisations toward outcome-based governance, while NHI Management Group’s NHI market research highlights how often visibility gaps persist even when teams believe coverage is broad.
- Inventory which vendor owns each identity lifecycle step: discovery, issuance, rotation, storage, approval, and revocation.
- Check whether vendor boundaries create duplicate admin paths or separate approval chains for the same NHI.
- Verify that service accounts and API keys are governed centrally, even if telemetry or enforcement is distributed.
- Measure how many tools can actually see the same workload identity and secret state at the same time.
Security teams should also test whether a vendor reduction plan improves incident response. Fewer products do not help if revocation still requires manual ticketing, multiple consoles, or inconsistent ownership between cloud, CI/CD, and SaaS teams. The strongest consolidation efforts remove duplicated privilege models and unify policy enforcement, while leaving best-in-class functions in place where they materially reduce risk. These controls tend to break down in hybrid enterprises where each business unit retains separate identity workflows because the integration effort is larger than the perceived vendor savings.
Common Variations and Edge Cases
Tighter consolidation often increases migration risk and operational overhead, requiring organisations to balance simplicity against continuity. There is no universal standard for how many vendors is “too many,” because the right number depends on whether the remaining stack covers discovery, policy, rotation, and revocation without gaps.
Some environments legitimately need multiple vendors, especially when one tool is stronger at runtime enforcement and another is better at secrets governance or cloud-native discovery. The mistake is treating overlap as waste without checking whether the overlap is providing resilience, segmentation, or independent verification. In regulated or highly distributed environments, current guidance suggests preserving redundancy where it improves assurance, then removing only duplicated decision points and duplicate credential stores. The NIST Cybersecurity Framework 2.0 supports this kind of outcome-based rationalisation, while NHI Management Group’s Ultimate Guide to NHIs — The NHI Market reinforces that visibility and rotation failures are often the real problem, not vendor count alone.
The practical test is simple: if a vendor reduction does not shorten revocation time, improve workload identity visibility, or reduce excessive privilege, it is probably a procurement change rather than a security improvement.
