How should MSPs reduce identity and device management sprawl without losing control?

Why This Matters for Security Teams

For MSPs, identity and device sprawl is rarely a tooling problem alone. It is an operating-model problem that turns into inconsistent onboarding, messy offboarding, duplicated policy logic, and client-by-client exceptions that are hard to audit. The result is fragmented control over MFA, endpoint posture, application access, and privileged access, even when each tool is “working” on its own. That fragmentation matters because it weakens the chain of trust across every managed environment.

Current guidance in the NIST Cybersecurity Framework 2.0 points teams toward clearer governance, but MSPs still need a practical consolidation strategy that preserves evidence and policy consistency. The risk is not just inefficiency. Identity overlap can obscure who approved access, which device was trusted, and whether revocation actually happened after a client change or incident. NHI Management Group’s Ultimate Guide to NHIs notes that only 5.7% of organisations have full visibility into their service accounts, which is a useful reminder that visibility gaps usually accompany control sprawl.

In practice, many security teams encounter a failed deprovisioning only after a client audit, account compromise, or offboarding dispute has already exposed the gap.

How It Works in Practice

The cleanest way to reduce sprawl is to define a source of truth for each control plane before consolidating anything. MSPs should map four distinct ownership domains: identity lifecycle, device posture, MFA enforcement, and application access. If one platform owns every decision, the model becomes simpler, but if multiple platforms are retained, the handoffs between them must be explicit, logged, and reversible. That is the real governance test.

A workable pattern is to consolidate by function rather than by vendor count. For example, identity should flow from a central directory or identity provider, device trust should come from a single endpoint posture system, and application permissions should be driven by policy rather than ad hoc ticket approvals. Offboarding should be triggered from a single event so that account disablement, token revocation, device unenrolment, and privileged access removal happen together. The NIST guidance on Zero Trust Architecture supports this approach by treating access as continuously evaluated, not permanently granted.

• Keep one authoritative identity record per client environment.
• Use one device trust decision path, even if multiple endpoint tools remain in place.
• Apply MFA policy centrally, with exceptions time-boxed and logged.
• Automate offboarding so revocation does not depend on manual follow-up.

For NHI-related workloads, the same logic applies to service identities, where lifecycle controls and visibility matter just as much as user access. NHI Management Group’s Lifecycle Processes for Managing NHIs reinforces that governance fails when ownership is unclear or rotation is inconsistent. These controls tend to break down when an MSP inherits multiple client directories with conflicting policy models because the integrations create more exceptions than the team can govern.

Common Variations and Edge Cases

Tighter consolidation often increases migration risk and operational overhead, requiring organisations to balance simplification against client-specific constraints. In multi-tenant MSP environments, a single global control stack may not be realistic if clients have different compliance obligations, device populations, or legacy authentication schemes. In those cases, current guidance suggests standardising the decision model first, then integrating the tools underneath it.

The main edge case is partial consolidation. Best practice is evolving here, and there is no universal standard for this yet. An MSP may keep separate endpoint and identity platforms while still enforcing one offboarding workflow and one audit trail. That can be acceptable if the control boundaries are clear and if exceptions are documented, but it becomes risky when duplicate systems each claim authority over the same access decision. Another common pitfall is over-centralising too quickly, which can create a single point of failure across all clients.

When the environment includes service accounts, API keys, or other non-human identities, the governance model should also account for secrets lifecycle and privileged access review. The broader NHI guidance in Top 10 NHI Issues is especially relevant where access is machine-to-machine rather than user-driven, because sprawl in those areas is often harder to detect than endpoint drift.
