Who should own autonomous agent identity governance in an organisation?

Why This Matters for Security Teams

autonomous agent identity governance fails when it is treated like a normal application ownership problem. Agents do not follow fixed user journeys, and their tool use can expand quickly as they chain prompts, APIs, secrets, and external actions. That means ownership cannot sit only with a workflow builder who understands the business process but not the identity boundary.

Current guidance from OWASP Agentic AI Top 10 and the NIST AI Risk Management Framework both point toward runtime governance, accountability, and continuous monitoring rather than static role assignment. For NHI teams, that means the identity owner must control issuance, revocation, policy, and auditability, while the workflow owner supplies intent and operational context. NHI governance also matters because the security gap is still material: NHIMG’s State of Non-Human Identity Security report notes that only 1.5 out of 10 organisations are highly confident in securing NHIs.

In practice, many security teams encounter privilege drift only after an agent has already accumulated permissions across multiple tools.

How It Works in Practice

Ownership should be split by function, not diluted by committee. Identity and security teams should own the control plane for autonomous agent identities: onboarding standards, workload identity, secret issuance, policy enforcement, revocation, logging, and periodic review. Business or platform teams should own the use case, the allowed actions, and the prompt or workflow design that expresses intent. That division keeps the identity boundary consistent while still allowing the agent to operate with business context.

The practical model is usually: create a unique workload identity for each agent, bind it to a specific trust domain, issue short-lived credentials per task, and evaluate access at request time. This is where CSA MAESTRO agentic AI threat modeling framework and the NIST AI Risk Management Framework are useful: they both reinforce governance, risk ownership, and runtime controls rather than trusting pre-approved access lists.

• Use identity and security teams to define how an agent is created, named, attested, and revoked.
• Use policy-as-code for authorisation so decisions reflect task context, not just the agent role.
• Issue ephemeral secrets and tokens only for the specific job the agent is executing.
• Require logging that ties each tool call back to the agent identity and the approving policy decision.

For deeper background, NHIMG’s Ultimate Guide to NHIs and Top 10 NHI Issues both show why credential lifecycle control and over-privilege remain core failure points. These controls tend to break down when the agent is embedded in a fast-moving DevOps or customer-support pipeline because local teams start bypassing central revocation and approval paths to preserve velocity.

Common Variations and Edge Cases

Tighter identity governance often increases delivery friction, requiring organisations to balance agent autonomy against review overhead. That tradeoff is real, especially when teams want agents to act across many services without repeated approvals. Current guidance suggests central identity ownership with delegated workflow control, but there is no universal standard for exactly how much authority a platform team should retain.

Edge cases usually appear in shared agent frameworks, multi-agent systems, and outsourced automation where no single product owner can see the full privilege chain. In those environments, the right answer is usually a central identity authority with domain-specific approvers, not fully decentralised ownership. If the agent can create sub-agents, request new tools, or call external APIs, the identity team should also govern delegation rules and revocation triggers.

This is also where 52 NHI Breaches Analysis and the OWASP Agentic AI Top 10 are useful reminders that compromise often follows over-privileged paths, not obvious failures. Where agent behaviour is highly dynamic, organisations should treat ownership as a shared operating model with identity security as the final authority on access boundaries.
