TL;DR: Non-human identities are made up of consumers, secrets, and entitlements, and the security failure usually appears when those three pieces are managed separately rather than as one governance problem, according to Entro Security. The real issue is not just credential exposure, but the access path and blast radius that follow it.
Editorial analysis by NHI Mgmt Group, based on content published by Entro Security: “The Three Elements of Non‑Human Identities”.
By the numbers:
- Non-human identities outnumber human identities by 92:1 in organizations.
Key questions
Q: What breaks when NHI consumers, secrets, and entitlements are managed separately?
A: Teams lose the ability to see how authentication and access combine into a single attack path.
Q: Why do overprivileged service accounts increase the impact of secret leakage?
A: Because the leaked secret authenticates the service account as itself, and the entitlement set determines how far that identity can move.
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 a named consumer owner Create an inventory that ties each service account, API key, token, and certificate to the workload or application that uses it, plus a human owner for accountability.
- Correlate secrets with actual entitlements Review whether each credential can only reach the resources the workload truly needs, then remove unused permissions that inflate blast radius.
- Treat overprivilege as a rotation trigger Rotate or revoke credentials when you cannot justify the access scope, not only when you suspect exposure or theft.
Bottom line: Non-human identity risk is not just a secret-management issue, because consumers and entitlements determine whether a leaked credential becomes a real breach path.

Consumers, secrets, and entitlements are a single governance unit, not three separate controls. The article’s strongest contribution is the reminder that NHI risk is structural, not just credential-centric. Security teams can discover a secret and still miss the workload using it, or understand the workload and still miss the access it carries. The practitioner conclusion is that NHI governance has to join identity, authentication, and authorisation into one control view.
A few things that frame the scale:
- 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Should organisations prioritise secret discovery or entitlement cleanup first?
A: If the environment already has broad, standing access, entitlement cleanup usually reduces risk faster because it shrinks the blast radius even before every secret is found. If there is active leakage, discovery and revocation come first. The right sequencing depends on whether exposure or overprivilege is the bigger immediate problem.
