By NHI Mgmt Group Editorial TeamBased on Akeyless: “Runtime Identity Security: The Next Evolution of Identity for AI Agents” (July 13, 2026)

TL;DR: Akeyless says AI agents now access databases, invoke APIs, update records, and make production decisions at machine speed, making one-time authentication insufficient for governance. Access review assumptions break when execution is continuous and controls must move from login to runtime action, context, and privilege.


At a glance

What this is: This is Akeyless's analysis of runtime identity security for AI agents, arguing that governing only initial authentication is no longer enough when agents keep acting after login.

Why it matters: It matters because IAM, PAM, and NHI programmes must decide how to control action-level authority for autonomous systems that can execute continuously without human intervention.

Context

Runtime identity security is the practice of governing an identity while it is actively performing work, not only when it first authenticates. That matters for AI agents because they can call tools, invoke APIs, and change context repeatedly inside a single session.

Traditional IAM assumes a stable human session with predictable actions and reviewable permissions. AI agents break that assumption because they operate continuously, can spawn dynamically, and may complete many privileged actions before any post-authentication review can occur.


Key questions

Q: What breaks when AI agents are governed only with login-based IAM?

A: Login-based IAM breaks because it stops at authentication and never evaluates the thousands of actions an autonomous agent may take after sign-in. The result is broad delegated access with no runtime control, which makes inherited credentials, token reuse, and chained actions effectively invisible to governance teams. Runtime authorisation is the missing control plane.

Q: Why do continuous AI agent actions increase security risk compared with human sessions?

A: Continuous agent actions compress decision, execution, and escalation into a short runtime window. That reduces the value of traditional review cycles and makes persistent privilege more dangerous, because an agent can complete many actions before a human can intervene or certify access.

Q: How do you know if runtime identity controls for AI agents are actually working?

A: They are working when agents cannot reuse credentials across tasks, cannot act outside declared intent, and cannot keep privilege after the approved action ends. If you still see durable tokens, broad session scope, or unreviewed production changes, the runtime control plane is not effective.

Q: What should IAM teams do before allowing AI agents to take production actions?

A: Define which systems the agent may touch, which tools it may call, what evidence will be logged, and where human approval is still required. If those boundaries are unclear, the agent can expand into actions the programme cannot meaningfully review. Governance must start before the first production workflow goes live.


Technical breakdown

Why login-time authentication fails for AI agents

Login-time authentication answers only the first question of trust: who or what is requesting access right now. For AI agents, that is insufficient because the risk changes after authentication as the agent selects tools, chains actions, and continues to execute. Runtime identity security moves the control point from session start to the moment of each action, which is closer to zero standing privilege than classic IAM. The architectural shift is from identity proof to continuous authorisation. Practical implication: treat authentication as an entry condition, not the governance boundary.

Practical implication: Move control decisions to the action layer, not just the login layer.

Dynamic credentials and zero standing privilege for agents

Dynamic credentials are short-lived credentials created for a specific task and destroyed when the task ends. In AI agent environments, that pattern reduces the value of any stolen token because the credential is not meant to persist. Zero standing privilege extends the same idea by ensuring access does not remain available between tasks. This is especially important when agents interact with databases, APIs, and infrastructure in production. Practical implication: give agents time-bounded access that disappears as soon as the approved action completes.

Practical implication: Use ephemeral, task-scoped access so compromised credentials do not persist.

Intent-based authorization and runtime authority

Intent-based authorization checks whether the requested action matches the agent’s current purpose, not just whether the identity technically has permission. That matters because an AI assistant may have database access for one task but should not be able to issue a destructive command outside that context. Runtime authority adds a continuous policy layer across commands, API calls, and privileged operations, which is closer to behavioural governance than static access control. Practical implication: bind allowed actions to the agent’s stated task and continuously reevaluate that binding as context changes.

Practical implication: Evaluate action purpose continuously, not just entitlement at issuance.


Threat narrative

Attacker objective: The objective is to turn a legitimate agent session into uncontrolled production access that can alter systems, expose data, or trigger destructive actions.

  1. Entry occurs when an AI agent receives broad credentials at login, even though its later actions are not yet known.
  2. Escalation happens as the agent chains tool calls, invokes APIs, and expands from one approved task into broader production access.
  3. Impact follows when the agent performs unintended actions across databases or infrastructure before any human review or session termination.

NHI Mgmt Group analysis

Runtime identity security is an assumption shift, not a feature addition. Traditional IAM assumes access can be granted, then reviewed later while the identity remains stable. That assumption no longer holds when AI agents make decisions and execute actions continuously across a session. The implication is that governance moves from periodic certification to action-time control.

Zero standing privilege becomes more important when the actor is autonomous. A human session can often be bounded by predictable intent and manual intervention, but an AI agent may create, call, and chain actions at machine speed. That makes persistent privilege a structural liability rather than just a hygiene issue. Practitioners should treat standing access as incompatible with autonomous execution.

Access review is the wrong control plane for agentic behaviour. Reviews examine what an identity had at a point in time, but AI agents may acquire and release privilege inside a single task window. That creates a governance blind spot where the credential exists long enough to be misused but not long enough to be meaningfully reviewed. Runtime evaluation and issuance-time policy are the relevant control plane.

Runtime Identity Security is a named concept for the identity blast radius problem. The article’s substance points to a broader category where discovery, ephemeral credentials, continuous enforcement, and forensic traceability converge around AI agent execution. That category matters because the real risk is not just authentication failure, but uncontrolled privilege propagation during live action. IAM teams should read this as a boundary problem, not a login problem.

Agentic identity governance must align identity proof, purpose, and execution time. For AI agents, those three elements are no longer separable governance steps. An agent can be authentic, authorized in principle, and still unsafe in context if its current action drifts from intent. The practical conclusion is that identity programmes need runtime policy, not only enrollment and entitlement management.

From our research library:

What this signals

Runtime control is now the deciding issue for agentic access. Once AI agents can call tools, mutate records, and run continuously, the old pattern of authenticating once and trusting the session no longer holds. IAM teams should expect more pressure to shift governance toward issuance-time policy, task scope, and explicit action approval rather than broader login controls.

Access review cadences were designed for stable privilege, not mutable agent behaviour. Access review processes assume access persists long enough to be certified; autonomous agents can acquire and release privilege within a single task window. In the 2026 Infrastructure Identity Survey, only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.

Ephemeral identity is becoming the practical default for high-risk agent workflows. The combination of dynamic credentials, zero standing privilege, and intent-based authorization suggests a new boundary for NHI and AI governance. Practitioners should prepare for architectures where the control plane is built around runtime conditions rather than permanent entitlements.


For practitioners

  • Define runtime control boundaries Map where AI agent decisions are allowed to continue after initial authentication and where action should be blocked, especially around production data and infrastructure changes.
  • Issue ephemeral credentials by task Replace reusable agent credentials with short-lived access that expires when the task ends, so privilege does not survive the approved action window.
  • Bind authorisation to declared intent Compare requested actions with the agent’s stated purpose and deny commands that fall outside the approved task, even when the agent technically has a credential.
  • Inventory agent identities and owners Create a living register of agent identities, entitlements, data access, and ownership so you can trace which agent performed each action and who is accountable.

Key takeaways

  • AI agents change the governance problem from authenticated access to controlled execution, because their actions continue long after login.
  • The article’s evidence shows that AI agent risk is already operational, not theoretical, and that review-based models are too slow for machine-speed behaviour.
  • The control that matters most is runtime policy over intent, scope, and ephemeral privilege, not broader standing access.

Key terms

  • Runtime Identity Security: Runtime Identity Security is the practice of protecting identities while they are actively being used by software, services, devices, or agents. It focuses on controlling authentication, authorization, secrets, and session behavior at execution time, so compromised credentials, excessive privileges, or abnormal identity actions can be detected and contained quickly.
  • Dynamic credentials: Dynamic credentials are secrets issued on demand and allowed to expire automatically after a defined use window. They reduce exposure by limiting how long a credential can be reused, but they only work when applications and access policies can support short-lived authentication without manual exceptions.
  • Zero Standing Privilege: A control model in which an identity does not keep persistent access unless it is actively needed. For NHIs, this means credentials and permissions are issued for a narrow task and then removed. It reduces the time window and reuse value of stolen access.
  • Intent-based authorisation: An access model that limits what an identity can do based on the task it is meant to complete. In practice, this means permissions are scoped to purpose, not just to system reach, so the actor cannot freely combine privileges beyond the approved intent.
