TL;DR: AI systems that choose tools, access data, and act on behalf of users have outgrown traditional risk management, and Akto’s guide argues for a repeatable framework covering inventory, taxonomy, scoring, mitigation, and continuous reassessment. The real shift is that AI risk is now an identity governance problem as much as a model-risk problem.
At a glance
What this is: Akto argues that AI risk assessment has become an identity governance discipline because agentic systems can act, chain tools, and hold permissions in ways classic software risk models do not cover.
Why it matters: IAM, IGA, PAM, and NHI teams need the same assessment discipline for AI agents that they already apply to other non-human actors, because autonomous access changes how risk is discovered, scored, and controlled.
Context
AI risk assessment is the repeatable process of finding AI systems, classifying their exposure, scoring their risks, and reassessing them as the system changes. The governance gap is that many security programmes still assume software behaves deterministically and can be reviewed on a fixed cadence.
In agentic systems, that assumption fails because the system can call tools, retrieve context, and take actions without a human in each step. That makes AI risk assessment relevant to identity governance, not just model oversight, because permissions, ownership, and revocation now shape the risk outcome.
Key questions
Q: What breaks when AI agents are evaluated like ordinary software functions?
A: Function-style tests assume fixed inputs produce fixed outputs, but agents are path-dependent and can choose different tools, memory paths, or timings on each run. That means a model may look correct in isolation while the surrounding system fails in production. Teams need trajectory-based evaluation, not just result checking, to understand real agent risk.
Q: Why do over-scoped AI agent permissions create more risk than human access in live systems?
A: Because an agent can execute decisions continuously inside one task, a single excessive permission can cascade into multiple system changes before anyone notices. Human review rhythms assume time for intervention, but autonomous execution compresses that window and turns scope mistakes into immediate operational impact.
Q: How do you know if AI risk measurement is working?
A: It is working when model behaviour, drift, exceptions, and control failures are visible after deployment, not just during testing. Effective measurement produces evidence that can trigger mitigation, escalation, or restricted use when the system no longer behaves within its approved risk boundary.
Q: Which frameworks help align AI data governance with identity controls?
A: NIST Cybersecurity Framework 2.0 is useful for structuring govern, identify and protect functions, while identity teams should extend that thinking to access, lineage and accountability. Where AI data access depends on delegated identities, the governance model should also map to lifecycle and least-privilege controls.
Technical breakdown
Why AI agents turn risk assessment into access governance
Agentic systems are not just models that generate text. They can select tools, move through a task sequence, and take action on behalf of a user, which makes identity and authorization part of the risk surface. Once an agent can call email, databases, payment APIs, or MCP-connected tools, the question is no longer only whether the output is safe. The real issue is whether the actor was allowed to reach that output path at all, and whether that allowance was scoped to the task, the session, and the data involved. That is why AI risk assessment needs to catalogue identities, permissions, and integrations, not just prompts and models.Practical implication: Treat AI system inventory as an access inventory, not a catalog exercise.

How runtime behaviour changes the meaning of control validation
Classic security reviews assume the system stays broadly stable between assessment cycles. The article describes a different pattern for AI, where models drift, prompts change, tools get added, and behaviour can shift after deployment. That means a control that passes in a lab may still fail under live traffic, especially when autonomous actions, shared context, or dynamic tool calls are involved. Risk scoring is only useful if the finding can be retested against the current runtime state. In other words, the control does not end at policy design. It must hold when the agent is actually operating.Practical implication: Validate AI controls in production-like conditions and reassess after each material change.

Where identity assumptions break in agentic workflows
The article points to excessive permissions, standing access, and shared service accounts as central AI risk drivers. Those are familiar identity issues, but the agentic context changes their impact because one manipulated decision can trigger several downstream actions in sequence. The same broad credential that looks manageable in a manual workflow becomes much harder to justify when the actor can link calls together faster than a human can intervene. This is where risk assessment, threat modelling, and identity governance converge. The assessment has to ask not only what data the system can see, but what it can do with that visibility across the whole tool chain.Practical implication: Score permission scope and tool reach as one combined governance risk, not separate reviews.
Threat narrative
Attacker objective: The attacker wants to turn a single manipulated interaction into wide-reaching action through the agent's own permissions and tool chain.
- Entry occurs when an agent receives broad credentials or tool access that lets it interact with email, databases, payment APIs, or MCP-connected services.
- Escalation follows when a manipulated prompt or poisoned tool response causes the agent to chain actions across multiple systems without human intervention.
- Impact appears when over-scoped access lets a single bad decision trigger real-world actions, data exposure, or repeated downstream system activity.
Breaches seen in the wild

NHI Mgmt Group analysis
AI risk assessment is now an identity governance control, not a standalone model-risk exercise. The article's core point is that agentic systems create a governance problem around who or what is allowed to act, not just how accurate a model may be. Once tools, data, and actions are in scope, inventory, classification, and review become identity disciplines. The practitioner implication is that AI programmes need the same ownership and lifecycle discipline already expected for NHI governance.
Deterministic review assumptions collapse when an AI system can change behaviour after deployment. Traditional risk programmes assume the thing being assessed remains recognisable until the next review cycle. The article shows that model updates, prompt edits, new integrations, and runtime behaviour can all reopen previously closed risk. The implication is that reassessment has to be triggered by material change, not calendar cadence alone.
Over-scoped access is the identity failure mode that turns AI into an execution path. The article repeatedly ties AI risk to broad credentials, shared service accounts, standing access, and linked tools. That is not merely a security control weakness. It is the point where identity governance allows a system to move from observation to action. Practitioners should treat blast radius, not model output, as the decisive variable.
Runtime validation is the governance layer that separates a controlled agent from an assumed-safe one. The guide is clear that static review is insufficient when autonomous action, loops, and tool misuse only emerge in production. That makes validation, monitoring, and re-scoring part of identity operations, not an occasional security add-on. The field needs programme designs that assume change, not exception handling.
AI agents force NHI governance to widen from credential hygiene to delegation governance. The article's inventory, taxonomy, and scoring model is really a governance model for delegated action. That matters because an AI agent can inherit reach across tools, context, and integrations in ways classic asset-based reviews do not capture. The practitioner conclusion is simple: governance must track delegated authority, not just stored secrets.
From our research library:
- 69% of security leaders agree identity management must fundamentally shift to address agentic AI systems, according to the 2026 Infrastructure Identity Survey.
- Half of companies using generative AI will deploy agentic AI by 2027, according to Deloitte's 2025 Technology Predictions.

What this signals
Runtime risk assessment is the control boundary that most AI programmes still lack. Static approval cannot see loops, unauthorized tool calls, or behaviour that only appears once the system is live. For practitioners, the practical shift is to treat runtime change as a governance event, not a logging detail.
AI risk assessment is becoming an inventory problem before it is a model problem. Once agents, tools, prompts, and connected systems proliferate, you cannot score what you have not discovered. That makes continuous discovery the prerequisite for any credible control plan.
Agentic AI changes the identity equation because delegated authority becomes operational, not hypothetical. Permissions, ownership, and revocation now determine whether a system can safely act in the world. For IAM and NHI teams, the lesson is to govern the act of delegation itself, not only the artefacts it leaves behind.
For practitioners
- Build a complete AI system inventory Track models, agents, vector stores, prompts, templates, tool integrations, and shadow deployments across cloud, on-prem, and employee devices.
- Classify AI assets by autonomy and exposure Separate low-risk internal assistants from public-facing or regulated-data agents so effort follows actual blast radius and decision scope.
- Score identity and tool risks together Assess broad credentials, shared service accounts, standing access, and connected tools as one combined governance problem.
- Retest controls after material change Reassess whenever models, prompts, tool links, or runtime behaviour changes rather than waiting for the next scheduled review.
Key takeaways
- AI risk assessment now spans identity, authorization, and governance because agentic systems can act across tools and data sources, not just generate outputs.
- Static reviews are insufficient when models, prompts, and integrations change after deployment, because the risk profile can shift at runtime.
- Programmes that inventory AI systems, score exposure, and retest controls on change are better positioned to control blast radius and satisfy auditors.

Key terms
- AI Risk Assessment: AI Risk Assessment is the structured process of identifying, analyzing, and prioritizing risks created by using artificial intelligence systems. It examines model behavior, data quality, security exposure, privacy impact, bias, misuse, and operational failure. In practice, it maps AI-specific threats to controls, owners, and residual risk decisions.
- Agentic Systems: Agentic systems are environments where AI agents can sequence tasks, invoke tools, and make runtime decisions without step by step human approval. They expand operational capability, but also introduce risks around privilege, observability, and unintended actions if guardrails are weak or poorly mapped to business intent.
- Runtime Risk Quantification: The practice of translating live workload exposure and security signals into estimated business impact. This helps teams prioritise response by linking technical activity to monetary or operational consequence, instead of treating every alert as equally urgent.
- Shadow AI: AI agents, copilots, or connected tools operating without full visibility or governance from security teams. Shadow AI becomes an identity problem when those systems authenticate with unmanaged tokens, service accounts, or OAuth apps that can reach production resources.
