TL;DR: Enterprise identity now requires two parallel layers: human authentication and machine identity governance, according to WorkOS. Astrix Security focuses on discovery, rotation, monitoring, and AI agent controls for the non-human identity layer, including API keys, service accounts, and OAuth tokens. The practical takeaway is that modern IAM programmes need separate control models for humans, workloads, and autonomous agents.
Editorial analysis by NHI Mgmt Group, based on content published by WorkOS: “Astrix Security vs. WorkOS: Non-Human Identity Meets Enterprise Authentication”.
By the numbers:
- for every human employee, there are roughly 100 non-human identities operating across cloud infrastructure, SaaS applications, and AI platforms.
Key questions
Q: What breaks when non-human identities are governed like human users?
A: Lifecycle triggers, ownership, and review processes stop working because machine identities do not generate joiner, mover, or leaver events.
Q: Why do service accounts and long-lived credentials undermine zero trust?
A: Service accounts and other long-lived credentials weaken zero trust because they create persistent access that attackers can reuse after a compromise.
Q: How should teams judge whether AI agent access is properly constrained?
A: Teams should look for whether the agent’s permissions are issued with narrow scope, short duration and explicit boundaries around which tools and resources it can use.
Practitioner guidance
- Map the machine identity estate Inventory API keys, service accounts, OAuth grants, workload identities and automation credentials across cloud, SaaS and AI systems.
- Separate human and non-human governance Run human authentication, role assignment and login assurance as one control plane, and NHI discovery, rotation and monitoring as another.
- Constrain agent access at issuance time Issue AI agent credentials with narrow scopes, short lifetimes and explicit tool boundaries, then verify token use against those constraints.
Bottom line: Machine identities now form a separate governance problem from human users, because their scale, persistence and access patterns do not fit employee IAM controls.

Identity governance has split into two control planes, not one. Human authentication and machine identity governance now solve different problems, with different lifecycles, owners and failure modes. Treating them as a single IAM programme creates blind spots around discovery, rotation and offboarding for credentials that never log in like a person does. Practitioners should design separate operating models for human access and NHI control.
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 is the difference between machine-to-machine authentication and machine identity governance?
A: Authentication answers whether a machine can prove it is allowed in at the moment of connection. Identity governance answers who owns the machine identity, what it can access, how long it should exist, and how quickly it must be revoked. Practitioners need both, because strong authentication without lifecycle controls still leaves persistent trust paths.
