Non-Human Identity Security at a Glance
Non-human identity security governs how software, workloads, automation, and AI systems authenticate, access resources, and interact with sensitive data.
Common Identities
Service accounts, APIs, workloads, applications, bots, containers, devices, and AI agents.
Common Credentials
API keys, access tokens, certificates, secrets, service credentials, and cryptographic keys.
Primary Risks
Excessive privilege, orphaned identities, exposed secrets, stale credentials, and unmonitored access.
Key Controls
Discovery, ownership, least privilege, credential rotation, behavior monitoring, and policy enforcement.
Related Concepts

Core Definition
What Is Non-Human Identity Security?
Non-human identity security is the practice of discovering, governing, monitoring, and protecting digital identities used by applications, workloads, services, APIs, automation, devices, and AI agents.
Unlike human identities, non-human identities authenticate and operate without direct user interaction. They often use API keys, tokens, certificates, service credentials, secrets, or workload identities to access data and systems.
These identities may have broad, persistent, or poorly understood permissions. Without clear ownership and continuous oversight, they can create hidden paths to sensitive data, cloud resources, business applications, and critical infrastructure.
Non-human identity security combines identity governance, secrets protection, access analysis, data context, behavioral monitoring, and automated remediation to reduce machine-driven access risk.
Related Terminology
Machine Identity
A digital identity assigned to a device, workload, application, service, bot, or automated process.
Service Account
An account used by software or services to authenticate and perform automated tasks.
Workload Identity
An identity assigned to a cloud, container, application, or computing workload.
Secrets Management
The secure storage, rotation, retrieval, and governance of credentials, keys, certificates, and tokens.
Identity Categories
Common Types of Non-Human Identities
Non-human identities operate across cloud, SaaS, applications, development environments, automation, infrastructure, and AI systems.
Service Accounts
Accounts created for applications, background services, scheduled jobs, integrations, and automated processes.
Workload Identities
Identities used by cloud workloads, virtual machines, containers, serverless functions, and orchestration platforms.
API and Integration Identities
Identities and credentials that allow applications and services to exchange data or initiate actions through APIs.
AI Agents and Bots
Autonomous or semi-autonomous systems that retrieve data, use tools, call APIs, and perform actions on behalf of users or workflows.
Security Lifecycle
How Non-Human Identity Security Works
Effective NHI security connects identity inventory, credential context, permissions, data access, activity, ownership, and remediation.
Discover
Inventory Non-Human Identities
Identify service accounts, workloads, applications, integrations, bots, AI agents, credentials, and secrets.
Attribute
Assign Ownership and Purpose
Determine which team owns each identity, why it exists, and which business process or application depends on it.
Analyze
Map Permissions and Data Access
Understand what systems, applications, infrastructure, and sensitive data each identity can access.
Prioritize
Identify High-Risk Access
Detect excessive privileges, stale identities, exposed credentials, unused access, and paths to sensitive data.
Enforce
Apply Least-Privilege Controls
Reduce permissions, restrict data access, rotate credentials, and enforce policies based on identity purpose and risk.
Monitor
Continuously Monitor Behavior
Track authentication, data access, tool use, permission changes, unusual activity, and policy violations.
Enterprise Risk
Why Non-Human Identity Security Matters
Non-human identities can operate continuously, access sensitive data at scale, and perform actions without direct human oversight.
Unmanaged Identity Sprawl
Cloud adoption, automation, APIs, DevOps, and AI create identities faster than many teams can inventory or govern them.
Excessive and Persistent Access
Machine identities may retain broad permissions long after the original application, integration, or workflow changes.
Credential and Secret Exposure
Hardcoded keys, leaked tokens, stale certificates, and shared secrets can give attackers direct access to systems and data.
Automated Data Exposure
Compromised or misconfigured identities can retrieve, transfer, modify, or expose sensitive data at machine speed.
Risk Reduction
Non-Human Identity Security Best Practices
Strong NHI security requires continuous visibility into identities, credentials, permissions, sensitive data access, behavior, and ownership.
Maintain a Complete Identity Inventory
Discover service accounts, applications, workloads, APIs, bots, AI agents, credentials, and secrets across every environment.
Assign Ownership and Business Purpose
Require a documented owner, approved purpose, expected behavior, and review process for every non-human identity.
Enforce Least-Privilege Access
Limit each identity to the minimum systems, resources, data, and actions required for its intended function.
Rotate and Protect Credentials
Eliminate hardcoded secrets, shorten credential lifetimes, rotate keys, and use managed identity or temporary access where possible.
Monitor Data Access and Behavior
Track which identities access sensitive data, call tools, change resources, or behave outside expected patterns.
Frequently Asked Questions
Non-Human Identity Security FAQs
Explore common questions about machine identities, service accounts, workload access, credentials, AI agents, and sensitive data.
What is non-human identity security?
Non-human identity security is the practice of discovering, governing, monitoring, and protecting the identities, credentials, permissions, and data access used by software and machines.
What is a non-human identity?
A non-human identity is a digital identity used by an application, service, workload, API, device, bot, automated process, or AI agent rather than a person.
What are examples of non-human identities?
Examples include service accounts, workload identities, application identities, API clients, bots, automation accounts, containers, devices, and AI agents.
Why are non-human identities a security risk?
Non-human identities often have persistent credentials, excessive permissions, limited ownership, and broad access to systems or sensitive data, making them valuable attack targets.
How is NHI security different from IAM?
IAM governs identities and access broadly. NHI security focuses on the unique lifecycle, credential, ownership, permission, and behavioral risks created by machine identities.
How are non-human identities related to secrets management?
Secrets management protects credentials such as keys, tokens, certificates, and passwords. NHI security adds identity ownership, permissions, data access, behavior, and lifecycle governance.
Are AI agents considered non-human identities?
Yes. AI agents can authenticate, retrieve data, call tools, access APIs, and take actions, so their identities and permissions require continuous governance.
How can organizations secure non-human identities?
Organizations should inventory identities, assign ownership, enforce least privilege, rotate credentials, remove stale access, monitor behavior, and evaluate access to sensitive data.
