TL;DR: Non-Human Identities outnumber human users 45:1 to 100:1 in cloud environments, according to Andromeda Security, and the larger risk is no longer credential theft alone but the blast radius created by over-privileged entitlements and weak lifecycle governance. Blast radius, not rotation alone, is becoming the decisive control variable for NHI security.
Editorial analysis by NHI Mgmt Group, based on content published by Andromeda Security: “The Non-Human Identity Security Crisis”.
By the numbers:
- Non-Human Identities outnumber human users anywhere from 45:1 to 100:1 in cloud environments.
- 95% of cloud identities are over-privileged.
Key questions
Q: What breaks when non-human identities have more access than they need?
A: When non-human identities carry excess access, a single compromise can move from a local incident to broad cloud control.
Q: Why do NHIs create a larger breach blast radius than human accounts?
A: NHIs often have persistent access, broad scopes, and machine-speed reach across many systems, so one compromise can affect multiple datasets quickly.
Q: How can organisations tell whether NHI governance is actually working?
A: NHI governance is working when every machine identity has an owner, a purpose, a minimum-necessary entitlement, and evidence of rotation and review.
Practitioner guidance
- Map every NHI to an accountable owner Create a complete inventory of service accounts, workload identities, API keys, tokens, and certificates, and bind each to a human sponsor who can approve retirement or scope changes.
- Right-size entitlements by actual usage Review the permissions attached to each NHI and remove unused or excessive access, especially where standing privileges are broader than the workload requires.
- Shift rarely used privileges to Just-in-Time elevation Reserve elevated access for exceptional actions and make the default permission set intentionally small so a stolen credential cannot automatically open high-impact paths.
Bottom line: The article's core warning is that NHI exposure is driven by privilege scope, not credential theft alone.

Blast-radius control is now the primary NHI security problem: once NHIs are numerous, ephemeral, and widely distributed, credential theft becomes less important than the permissions attached to the identity. A stolen secret is only the entry point; over-privileged entitlements decide whether the event stays local or becomes enterprise-wide. The practitioner conclusion is straightforward: governing scope matters more than governing secret format.
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: What should teams do when an NHI credential is compromised?
A: Contain the identity first by revoking or rotating the credential, then immediately review the permissions attached to that account and remove any standing access that exceeds the workload's actual need. Without scope reduction, the same compromise can be reused elsewhere.
