TL;DR: P0 Security argues that machine identities now outnumber people in most environments, yet they still sit outside the governance perimeter because teams treat them as static configuration rather than governed identities with accountable lifecycle ownership. That assumption collapses least-privilege and offboarding models built for humans, leaving permissions to drift until something breaks.
Editorial analysis by NHI Mgmt Group, based on content published by P0 Security: “Close the NHI Governance Gap”.
By the numbers:
- Machine identities are outpacing human users in most environments by a factor of 20+ to 1.
Key questions
Q: What breaks when machine identity is treated as an infrastructure detail?
A: What breaks is accountability.
Q: Why do service accounts and workloads with unclear ownership create governance risk?
A: Unclear ownership turns non-human identities into unmanaged access paths.
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
- Define lifecycle ownership for every NHI Attach a named person or team to each service account, workload identity, and automation credential at provisioning time so reviews and revocation have a clear accountable owner.
- Expire machine access by default Set renewal and expiry as the normal path for machine credentials so access cannot persist indefinitely without an explicit business justification.
- Embed identity creation into CI/CD controls Require provisioning checks in deployment pipelines so machine identities are created with ownership, scope, and lifetime metadata before they reach production.
Bottom line: Machine identities become a governance problem when they are handled as static objects instead of identities with owners, expiry, and removal paths.

P0 Security's full article covers the operational detail this post intentionally leaves for the source:
- How to tag ownership at the point of provisioning so every machine identity has a responsible team
- How to enforce expiration and renewal as defaults inside infrastructure and deployment workflows
- How to integrate identity creation controls directly into CI/CD workflows without breaking delivery
- How to run drift detection continuously across service accounts, workloads, and automation identities

Static treatment of machine access is the core governance failure here: NHIs were designed to be governed as identities, not frozen as configuration objects. When teams treat them as static, lifecycle controls such as ownership, expiry, and renewal stop functioning as governance mechanisms. The implication is that the control model itself must change, because static admin assumptions do not match machine behaviour.
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: What is the difference between managing user access and NHI access for AI projects?
A: User access management focuses on people who can authenticate directly, while NHI access management covers the service accounts, tokens, bots, and automation identities that keep AI systems running. In AI projects, the non-human layer often carries the more durable privilege and the harder-to-see risk.
