They should contain the access path before expanding the agent’s reach, then assign ownership, review the connected secrets and roles, and decide whether the integration belongs in scope at all. The important issue is not just removing access, but deciding whether the identity should have existed in production in the first place.
Why This Matters for Security Teams
When an AI agent is discovered outside governance, the problem is usually broader than a single misconfigured account. Autonomous systems can chain tools, reuse tokens, and act on objectives faster than human operators can review each step, so a delayed response can turn one unapproved integration into a wider access event. Current guidance suggests treating the agent as an active workload identity, not a static application, and the OWASP Agentic AI Top 10 frames this as a governance and control failure, not just an inventory issue. NHIMG research on the State of Non-Human Identity Security found that only 1.5 out of 10 organisations are highly confident in securing NHIs, which reflects how quickly visibility gaps become operational gaps. In practice, many security teams encounter the real impact only after the agent has already touched production data or credentials, rather than through intentional review.
How It Works in Practice
The first step is to contain the agent’s access path, not to debate ownership while the integration remains active. That usually means disabling the token path, revoking connected secrets, and blocking any brokered access that the agent can still reach through delegated permissions. For autonomous workloads, static RBAC is often too blunt because it assumes stable, human-like access patterns. Better practice is evolving toward intent-based authorisation, where the request is evaluated at runtime using context such as task, destination, data sensitivity, and expected duration.
Teams should then map the agent to a workload identity primitive, such as SPIFFE/SPIRE or OIDC-backed service identity, so there is cryptographic proof of what the agent is and what runtime issued it. That identity should be paired with just-in-time, short-lived credentials instead of long-lived static secrets. The operational goal is to make access narrow enough that it expires with the task, and visible enough that it can be revoked immediately if behaviour diverges.
Policy-as-code matters here because an agent can change behaviour mid-run. Runtime controls aligned with the NIST AI Risk Management Framework and the CSA MAESTRO agentic AI threat modeling framework help teams decide whether the agent’s action is still within approved bounds. NHIMG’s OWASP NHI Top 10 and Lifecycle Processes for Managing NHIs both point to the same operational pattern: find the identity, isolate its paths, review its privileges, and decide whether it belongs in production at all. These controls tend to break down when the agent is embedded in a distributed workflow with multiple downstream tokens, because revocation may not reach every delegated session quickly enough.
Common Variations and Edge Cases
Tighter containment often increases operational friction, requiring organisations to balance faster remediation against the risk of interrupting legitimate automation. There is no universal standard for this yet, especially when an agent belongs to a vendor-managed platform, a multi-agent pipeline, or an LLM-driven system that spawns child tools dynamically. In those cases, the first question is whether the agent can be paused safely without losing forensic evidence. The second is whether the runtime can prove which secrets, prompts, and downstream services were in play.
Some environments will have no clean owner because the agent was introduced through a product team, a pilot, or a third-party integration. Best practice is to assign a business owner and a technical owner separately, then decide whether the identity is approved for continued use or should be retired. In more mature programs, this review is paired with policy checks against approved use cases, data classes, and allowed tool sets. Where current guidance is strongest is on short-lived credentials and explicit authorization; where it is still evolving is on how much autonomy can remain before the agent should be treated as out of scope entirely. Teams that delay that decision usually keep the risk alive longer than the integration itself.
