TL;DR: Machine identities, secrets, and AI agents are spreading across code, vaults, chat tools, and cloud services, with Entro claiming discovery across 1,200 NHI types and 70-plus sources, according to SailPoint’s acquisition of Entro. The control question is no longer visibility alone, but how far identity governance can reach into runtime access, ownership, and remediation before exposure becomes unmanageable.
Editorial analysis by NHI Mgmt Group, based on content published by SailPoint: “Adding a world-class striker to the SailPoint portfolio: How Entro is raising our game”.
By the numbers:
- Entro discovers over 1,200 types of NHIs across 70+ critical cloud and developer infrastructure sources.
- Entro scans entire ecosystems across 70+ critical cloud and developer infrastructure sources.
Key questions
A: The failure is assuming a central vault or periodic review can cover the whole estate.
Q: Why does ownership matter so much for NHI governance and AI agents?
A: Ownership turns an exposed identity into an accountable governance object.
Q: Why do periodic access reviews fail for high-churn machine identities?
A: Because review cycles assume identity state stays stable long enough to be observed and certified.
Practitioner guidance
- Map the full NHI estate beyond secret vaults Extend discovery into code repositories, collaboration tools, container registries, configuration files, and SaaS audit logs so hidden machine identities are not missed.
- Bind every NHI to a human owner Require each token, key, certificate, and agent identity to resolve to a named owner, business purpose, and offboarding path before it is accepted into governance workflows.
- Move from periodic review to runtime control Add behavioural baselines, anomaly detection, and automated revocation so excessive privilege or tool misuse can be contained while the identity is still active.
Bottom line: The article’s core issue is not NHI visibility alone but whether discovery can lead to ownership, revocation, and runtime enforcement across the full machine identity surface.

NHI governance is shifting from inventory management to control-plane design: Discovery is no longer the hard part by itself. The harder question is whether the governance model can bind ownership, lifecycle action, and runtime enforcement to every machine identity and agent that matters. That is where most programmes still thin out. The practitioner conclusion is that inventory only has value when it feeds an enforceable control plane.
A few things that frame the scale:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: How should teams govern sanctioned AI agents and shadow AI differently?
A: Sanctioned agents can be governed through approved ownership, policy, and runtime controls, while shadow AI requires discovery first because it may not appear in standard inventories. The practical difference is that one needs enforcement and the other needs exposure reduction before governance can begin.
