TL;DR: As enterprises accelerate digital transformation, unmanaged identities, orphaned accounts, and sprawl across hybrid environments are creating a blind spot that SSO and MFA cannot cover, according to SPHERE. Non-human identities now outnumber human identities 82 to 1, making upstream hygiene and continuous evidence-driven monitoring central to IAM and PAM governance.
NHIMG editorial — based on content published by SPHERE Technology Solutions: the VMblog Q&A on identity hygiene and non-human identity sprawl
By the numbers:
- In the article, non-human identities outnumber human identities 82 to 1.
Questions worth separating out
Q: How should security teams govern non-human identities in hybrid environments?
A: They should treat non-human identities as a governed population with ownership, lifecycle, and entitlement controls, not as an by-product of application delivery.
Q: Why do SSO and MFA fail to control NHI risk?
A: SSO and MFA mainly protect human authentication flows.
Q: When should organisations move from point-in-time reviews to continuous identity monitoring?
A: They should move when identity state changes faster than their review cycle can meaningfully observe.
Practitioner guidance
- Inventory non-human identities continuously Build a living inventory of service accounts, API keys, certificates, and other machine identities across hybrid platforms, and assign an owner to every record.
- Reconcile privileged access before PAM expansion Clean stale accounts, orphaned entitlements, and inherited AD groups before extending privileged access workflows into new environments.
- Shift compliance from snapshots to evidence streams Collect current proof of ownership, rotation status, and usage for each identity so auditors can verify control health continuously rather than quarterly.

- How the vendor frames upstream hygiene for Active Directory modernisation and identity clean-up.
- The practical link between identity hygiene and PAM programme value in hybrid environments.
- Why compliance is moving from point-in-time assessment toward continuous evidence collection.
- How the article connects current identity risk to M&A consolidation and agentic AI automation.

Identity hygiene has become the missing control plane for hybrid IAM. SSO and MFA are necessary, but they do not solve discovery, ownership, or entitlement drift for service accounts and other machine identities. The real problem is that enterprises still treat identity as a login event instead of a continuously changing asset inventory. That leaves boards with a false sense of coverage. Practitioners should treat hygiene as a governing layer, not an afterthought.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to Ultimate Guide to NHIs.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
A question worth separating out:
Q: What does upstream hygiene mean for PAM programmes?
A: Upstream hygiene means cleaning identity records, ownership data, and entitlement mappings before privileged access controls try to enforce them. If source data is stale or polluted, PAM simply manages inherited risk more efficiently. Teams should use it to reduce privilege sprawl at the identity layer first, then harden privileged workflows on top.
