Compare them by governance coverage, not interface depth. A tool that manages M365 well can still leave gaps if it does not discover shadow SaaS, support access reviews across the wider app estate, and enforce offboarding end to end. The right question is whether it can preserve a complete entitlement record across systems, not whether it is strong inside one tenant.
Why This Matters for Security Teams
Microsoft 365 admin tools are valuable inside the tenant, but identity risk rarely stays inside one tenant. Security teams need to know whether a platform can govern the full entitlement lifecycle across SaaS, third-party apps, and privileged service accounts, not just mailboxes and users. That distinction matters because shadow access and stale permissions often sit outside the Microsoft control plane, where local admin tooling cannot see or remediate them. NIST CSF 2.0 frames this as a governance and inventory problem, not a console problem, and NHIMG research shows why that matters: only 5.7% of organisations have full visibility into their service accounts, and 80% of identity breaches involved compromised non-human identities such as service accounts and API keys. See also the Ultimate Guide to NHIs and NIST Cybersecurity Framework 2.0 for the governance lens. In practice, many security teams discover the gap only after an offboarding failure or third-party compromise has already exposed it.
How It Works in Practice
Compare the tools by asking what they can discover, govern, and revoke across the entire identity estate. Microsoft 365 admin tooling is usually strongest for native objects such as users, groups, licenses, Exchange, SharePoint, Teams, and tenant-specific settings. A broader identity governance platform should extend beyond that boundary and maintain a complete entitlement record across cloud apps, on-prem systems, business applications, and connected NHIs. That includes access reviews, joiner-mover-leaver workflows, privileged role governance, and evidence trails that survive audits.
A practical evaluation usually covers five questions:
- Can it discover and normalize entitlements outside Microsoft 365, including shadow SaaS and delegated access?
- Can it orchestrate offboarding end to end, including revocation of tokens, API keys, app consents, and service accounts?
- Can it enforce periodic access reviews across both human and non-human identities?
- Can it preserve lineage, ownership, and approval history for each entitlement?
- Can it trigger compensating controls when a connected app cannot be fully governed?
That broader view matters because NHIMG research shows 92% of organisations expose NHIs to third parties, and only 20% have formal processes for offboarding and revoking API keys. The State of Non-Human Identity Security and the Lifecycle Processes for Managing NHIs section show why lifecycle control is the real test, not interface depth. Identity governance platforms also tend to align better with NIST-style lifecycle controls and audit evidence because they can demonstrate who had access, why, and for how long. These controls tend to break down when organisations rely on Microsoft-only administration in hybrid estates with multiple IdPs, unmanaged SaaS, and machine identities that never pass through the M365 control plane.
Common Variations and Edge Cases
Tighter governance often increases deployment and integration overhead, requiring organisations to balance breadth of coverage against implementation speed. A Microsoft-first approach can be sufficient in a tightly standardized tenant with limited external apps, but that is an operational exception, not the norm. Best practice is evolving on how much of the identity estate should be managed by one platform versus federated across multiple systems, so teams should label that decision explicitly rather than assume parity.
Some edge cases deserve special attention. If the question is only about basic M365 lifecycle tasks, native admin tools may be faster and cheaper. If the environment includes mergers, shadow IT, contractors, or machine access to shared resources, broader governance is usually the safer default. For audit-heavy environments, the deciding factor is often whether the platform can produce a single entitlement record and a complete revocation trail across systems. If not, the organisation may have good control over Microsoft 365 while still carrying unresolved access risk elsewhere. The Top 10 NHI Issues is useful here because it highlights how visibility, rotation, and offboarding failures frequently coexist rather than appear in isolation.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0 and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | ID.AM-01 | Identity asset inventory is central to comparing tenant tools with wider governance. |
| OWASP Non-Human Identity Top 10 | NHI-01 | NHI discovery and lifecycle coverage are key gaps in Microsoft-only administration. |
| NIST AI RMF | Governance and accountability apply when access spans multiple identity systems. |
