TL;DR: Machine identities now outnumber human identities and often outlive the reviews meant to govern them, according to Fischer Identity’s blog on machine identity governance. The real issue is not volume alone, but the assumption that identity can be managed on human timelines when workloads, tokens, and agents operate at machine speed.
Editorial analysis by NHI Mgmt Group, based on content published by Fischer Identity: “Machine Identity at Scale: How Fischer Identity Governs Non-Human Identities Without Slowing the Business”.
Key questions
Q: What breaks when quarterly access reviews are used for non-human identities?
A: Quarterly access reviews break when applied to non-human identities because the control assumes stable identities, known ownership, and slow entitlement change.
Q: What problem does ownership attribution solve for service accounts and API keys?
A: It closes the gap between exposure detection and accountable remediation.
Q: How do teams know if machine identity governance is actually working?
A: Look for evidence that each service account has a current owner, a narrow purpose, a short credential lifetime, and a clear retirement path.
Practitioner guidance
- Inventory every non-human identity Create a complete register of service accounts, API keys, workload identities and AI-agent credentials, then classify each by owner, purpose, environment, scope and expiry.
- Make owner attribution mandatory Block activation until each machine identity has a named accountable owner or team, with approval paths for sensitive entitlements tied to that owner.
- Replace periodic reviews with event-driven governance Trigger lifecycle controls from pipeline runs, deployment events and termination events so provisioning, renewal and decommissioning happen at the same speed as the workload.
Bottom line: Machine identities create a governance problem that human-centric IAM models were never designed to absorb.

Machine identity governance fails when review cadences assume access persists long enough to be reviewed: that premise was designed for human-paced administration, not ephemeral workloads, tokens and agents. When identities are created, used and retired inside short automation windows, quarterly certification cannot observe the full lifecycle. The implication is that governance must move from review-based administration to event-based control.
A few things that frame the scale:
- NHIs outnumber human identities by 25x to 50x in modern enterprises, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should security teams govern machine identities differently from human users?
A: Security teams should govern machine identities with lifecycle, context, and runtime controls, not human approval workflows. That means separate ownership, purpose-based entitlement, expiry, and revocation for service accounts, bots, and agents. Human IAM can inform the model, but machine access needs faster review, tighter scoping, and automated enforcement.
