TL;DR: Non-human identity risk can be reduced without deleting credentials or modifying infrastructure by using deny-based quarantine, because NHIs are often invisible, overprivileged, and deeply embedded in production systems, according to Apono. The underlying governance problem is that revocation is treated as the only remediation path, even though many identity controls assume access can be removed without breaking service continuity.
Editorial analysis by NHI Mgmt Group, based on content published by Apono: “Why Reducing Risk from Non-Human Identities Shouldn’t Break Your Infrastructure”.
By the numbers:
- The ratio of NHIs to humans has jumped to 45:1.
Key questions
Q: What breaks when organisations remove NHI access without understanding dependencies?
A: Service accounts, automation tokens, and CI/CD integrations can fail immediately when permissions are removed without mapping downstream dependencies.
Q: Why do service accounts and API tokens make application exploits worse?
A: Service accounts and API tokens extend a host compromise into other systems because they carry machine authority beyond the vulnerable process.
Q: How should security teams reduce NHI risk without breaking production systems?
A: Start by identifying which machine identities are actually embedded in live workflows, then apply the least disruptive control that reduces exposure.
Practitioner guidance
- Build a complete NHI inventory Discover service accounts, API tokens, CI/CD integrations, and other machine credentials across cloud, infrastructure, and SaaS environments.
- Quarantine before revoking access Use deny policies to block risky or dormant NHIs first when their downstream dependencies are unclear.
- Prioritise high-blast-radius identities Focus first on privileged NHIs, dormant identities, and accounts that span multiple environments.
Bottom line: NHI risk management fails when teams assume revocation is the only safe response to excess privilege, because many machine identities are embedded in production workflows.

NHI blast-radius control is becoming more important than access removal. The article shows that the real operational constraint is not whether a risky identity should lose access, but whether a control can reduce exposure without breaking production dependencies. That shifts governance from a revocation-first mindset to one that recognises dependency-aware containment as a legitimate state. For practitioners, the key question is how to reduce blast radius without forcing infrastructure change.
A few things that frame the scale:
- 59% of organisations say they lack viable alternatives to standing privileged access for NHIs and AI agents, according to Delinea research.
A question worth separating out:
Q: What is the difference between quarantine and revocation for non-human identities?
A: Quarantine blocks access while keeping the identity object and underlying infrastructure intact, so it is reversible and less disruptive. Revocation removes the permission path entirely, which is safer only when the dependency impact is known and the identity is no longer operationally required.
