What is Non-Human Identity?
The service accounts, API keys, and AI agents that access systems - now outnumbering human users many to one.
Non-Human Identity: definition
Modern systems are run largely by software talking to software. Non-human identities - service accounts, API keys, secrets, and increasingly AI agents - now vastly outnumber human accounts in most organizations. They are powerful and often over-privileged, long-lived, and poorly tracked, making them a growing attack surface. As AI agents begin to take actions autonomously, governing what each non-human identity can do, and holding it accountable, becomes central to security.
- Service accounts, API keys, tokens, secrets, and AI agents
- Often outnumber human identities many times over
- Tend to be over-privileged, long-lived, and under-monitored
- A rising risk as autonomous AI agents take real actions
How Fintra handles it
Fintra treats AI agents as governed identities: they operate under least-privilege access, within policy guardrails, and every action is attributed and logged to a tamper-evident trail. Crucially, an AI agent cannot unilaterally complete a consequential action - a named human approves it - so a non-human identity is accountable and constrained rather than an unchecked actor.
- AI agents run under least-privilege, policy-bound access
- Every agent action attributed and logged
- Consequential agent actions require human approval
Worked example
Frequently asked questions
What is a non-human identity?
Any account used by software rather than a person - service accounts, API keys, tokens, secrets, and AI agents. They authenticate to systems and take actions just as human accounts do, but belong to machines and applications, so they need their own governance.
Why are non-human identities a security risk?
They often outnumber human accounts, tend to be over-privileged and long-lived, and are frequently unmonitored and unowned. That makes them an attractive, easily overlooked target for attackers. As AI agents act autonomously, ungoverned non-human identities become even riskier.
How do you secure non-human identities?
Apply least privilege, assign an owner to each, rotate credentials regularly, monitor and log their activity, and remove unused accounts. For AI agents specifically, constrain what they can do and require human approval for consequential actions, as Fintra does.
How are AI agents different from traditional non-human identities?
Traditional service accounts run fixed, predictable tasks. AI agents can reason and choose actions dynamically, making their behavior less predictable and their governance more important. Treating agents as accountable identities - scoped, logged, and human-approved for big actions - is essential.
