TL;DR: Non-human identities now outpace human identities by 45:1 in modern enterprises, and traditional security tools struggle to manage their dynamic, distributed access patterns, according to Aembit. The governance gap is structural: IAM teams need lifecycle controls, policy enforcement, and rotation discipline built for workloads, not users.
Editorial analysis by NHI Mgmt Group, based on content published by Aembit: “A Human’s Guide to Non-Human Identities (NHIs)”.
Key questions
Q: What breaks when non-human identities are managed outside the IAM operating model?
A: What breaks is accountability.
Q: Why do service accounts create more risk than many teams expect?
A: Service accounts create risk when they accumulate privileges, outlive the workload that needed them, or remain embedded in code and automation.
Q: How do security teams know if NHI governance is actually working?
A: A working NHI programme shows clear ownership, short-lived credentials, frequent revocation, and low numbers of dormant or shared machine accounts.
Practitioner guidance
- Map every NHI to an accountable owner Create a register for service accounts, API keys, tokens, and certificates that records purpose, environment, resource scope, and business owner.
- Replace standing access with policy-based issuance Grant workload access only at request time using context-aware policy decisions tied to workload identity, environment, and target resource.
- Shorten secret lifetime and revoke on change Set rotation and revocation triggers for deployment changes, integration changes, and workload teardown so credentials do not outlive the service they support.
Bottom line: The core problem is governance mismatch: human-oriented IAM does not fit machine identities that are created, reused, and retired at cloud speed.

NHI governance failed because IAM was built around human stability, not machine volatility. The article makes clear that NHIs are created, reused, and retired on a different cadence from employees, yet most control models still assume a stable subject with a long review horizon. That mismatch is why user-centric governance leaves workloads under-governed. Practitioners should treat NHI identity as its own lifecycle domain, not as an extension of employee IAM.
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: Should organisations automate secret rotation or keep it manual?
A: Organisations should automate detection and rotation wherever secrets are numerous, short-lived, or business-critical. Manual processes are too slow to keep pace with real-world drift, especially when the security goal is not just rotation but confirmation that the new secret is actually in use.
