TL;DR: Gartner’s Shadow AI Is Creating Opportunity for Product Leaders report says more than 60% of enterprise employees now use unsanctioned AI tools and 35% of organizations have detected AI agents reaching external servers, widening governance gaps across data, access, and review, according to Akto’s summary of the report. Shadow AI has shifted from visibility problem to control problem, and discovery only matters when it is tied to policy enforcement and validation.
At a glance
What this is: Akto’s analysis says shadow AI is no longer just a discovery problem; it is a governance control problem because unmanaged tools and agents can move data outside approved boundaries before teams can review them.
Why it matters: IAM, NHI, and AI security teams need to treat shadow AI discovery as an enforcement point, not a reporting exercise, because governance fails when usage cannot be tied to identity, privilege, and policy.
By the numbers:
- More than 60% of enterprise employees now use unsanctioned AI tools, according to Akto’s summary of Gartner’s report.
- 35% of organisations have detected AI agents reaching external servers, according to Akto’s summary of Gartner’s report.
Context
Shadow AI becomes a governance problem when unsanctioned tools, agent workflows, and external model calls outpace the organisation’s ability to inventory, approve, and validate them. The primary issue is not adoption alone, but the lack of control over where data goes, which identities act, and whether those actions are tied to policy.
For IAM and NHI teams, the important boundary is between discovery and enforcement. If AI usage is not linked to least privilege, data-loss controls, and identity-bound accountability, the organisation can see the risk but still fail to contain it. That makes shadow AI similar to other unmanaged identity estates: visibility without lifecycle control is incomplete governance.
Key questions
Q: What breaks when shadow AI controls stop at visibility and do not include enforcement?
A: Visibility alone tells you that unsanctioned AI exists, but it does not prevent leaks. Users can still paste PHI, cardholder data, source code, or secrets into unmanaged tools. Without enforcement, governance becomes an audit exercise with no operational impact, and the highest-risk data still leaves the organisation.
Q: Why do unsanctioned AI tools create the same governance problems as shadow IT?
A: Unsanctioned AI use creates shadow IT risk because users often route around restrictions when a tool is blocked. That leaves security teams chasing exception lists instead of managing the real behaviour. The core issue is loss of visibility. Once teams cannot tell what is being used, they cannot consistently apply access, data handling, or monitoring controls.
Q: How do security teams know if shadow AI is actually under control?
A: Security teams know shadow AI is under control when they can inventory every agent, model workflow, and tool connection, then map each one to an owner and access scope. If they cannot explain who owns it, what it can access, and when it was last reviewed, it is not controlled.
Q: What is the difference between shadow IT and shadow AI?
A: Shadow IT is the use of unapproved software, while shadow AI is the use of unapproved or unmanaged generative AI services and embedded copilots. Shadow AI is harder to govern because it often hides inside sanctioned SaaS tools and can move data into external model systems without obvious signs.
Technical breakdown
Why shadow AI discovery becomes a control plane problem
Shadow AI discovery is the process of finding unsanctioned AI tools, model calls, and agent workflows across the environment. By itself, discovery is only inventory. It becomes a control plane when findings are linked to identity, access policy, data handling rules, and approval states so the organisation can decide whether a tool may continue operating. In practice, the failure mode is common: teams detect usage after sensitive data has already crossed into an external model or workflow, which means the control has arrived too late to shape the transaction.
Practical implication: Treat discovery outputs as inputs to access enforcement, not as a reporting dashboard.
How unmanaged agents bypass traditional review cycles
AI agents change the governance model because they can request, route, and process data at machine speed, often outside the cadence of human review. Traditional approval and code review processes assume slower change and clearer ownership. Agentic workflows break that assumption by turning decisions into runtime actions, which makes data classification, privilege boundaries, and gateway enforcement more important than periodic review alone. This is especially relevant where agents connect to external servers or third-party models, because those links can expand the trust boundary without a corresponding access decision.
Practical implication: Centralise agent permissions and validate every outbound model or API path before it is allowed to run.
Why AI governance needs identity-bound enforcement
AI governance fails when the organisation cannot connect a tool, model, or agent to a specific accountable identity and policy. That is the same structural issue NHI programmes address for service accounts and tokens: if the actor is not governed as an identity, it can operate beyond the intended boundary. In shadow AI cases, the challenge is not only sanctioned versus unsanctioned use, but whether access, data movement, and redaction are controlled at runtime. Without that link, the organisation cannot prove who or what used the system, what it touched, or whether the data path was authorised.
Practical implication: Bind AI usage to identity, privilege, and logging so governance decisions are enforceable at runtime.
Threat narrative
Attacker objective: The effective objective is to extract or expose sensitive enterprise data through unmanaged AI usage before governance controls can block the flow.
- Entry begins when employees adopt unsanctioned AI tools or connect approved AI features to external LLMs without security review.
- Credential or policy abuse follows when agents and tools operate with broader access than the organisation intended, allowing sensitive data to leave approved boundaries.
- Impact occurs when customer PII, product logs, or proprietary data are exposed to third-party models or external servers outside governance control.

NHI Mgmt Group analysis
Shadow AI discovery has become a governance control, not a visibility exercise. Once employees can route data into unsanctioned tools faster than security can review them, discovery alone is only an inventory function. The board-level question is whether discovery feeds enforcement, redaction, and identity-bound policy decisions. Without that chain, the organisation can measure exposure but cannot govern it.
Identity is the missing control surface in most shadow AI programmes. AI usage that cannot be tied to a accountable identity, privilege scope, and approved data path behaves like unmanaged NHI activity. The practical consequence is that AI governance and NHI governance are converging on the same runtime question: who or what is allowed to act, on which data, under which policy?
Runtime control matters more than periodic review when AI systems act at machine speed. Review cadences designed for human workflows cannot keep up with agentic actions, especially when external model calls and API paths are created dynamically. Shadow AI governance debt: the backlog created when discovery exists, but enforcement, approval, and validation do not keep pace. Practitioners should treat that debt as a measurable governance gap, not an abstract risk.
Centralising agent workflows is now a defensible architectural pattern. When agents are forced through governed gateways, least-privilege scopes, and redaction controls, security teams regain a decision point before data leaves the boundary. That does not eliminate shadow AI, but it makes the risk governable rather than merely observable.
AI security and NHI security are meeting at the same policy boundary. As enterprises operationalise AI, they will need inventory, ownership, lifecycle control, and revocation for both human and non-human actors. The organisations that align those controls early will have a much cleaner path to defensible AI adoption.

What this signals
Shadow AI governance debt: organisations are accumulating a gap between discovery and enforcement, and that gap becomes visible only when AI usage is tied to identity, access, and data boundaries. The strongest programmes will treat AI discovery as an input to lifecycle control, not as a standalone visibility layer.
For IAM and NHI leaders, the practical signal is clear: if an AI workflow can touch data without an accountable identity, it is already outside the governance model. That is why shadow AI should be managed with the same lifecycle discipline used for service accounts, tokens, and other non-human actors.
For practitioners
- Implement continuous shadow AI discovery Scan internal environments, SaaS usage, and developer workflows for unsanctioned AI tools, external LLM calls, and hidden agent integrations. Tie each finding to an owner, a data classification, and an allow or block decision.
- Bind AI usage to policy-enforced identity Require accountable identities for agents and AI-enabled workflows so access logs, privilege scopes, and approval states can be audited together. Treat unmanaged agents like other high-risk non-human identities.
- Route agents through governed gateways Force agentic workflows through central gateways that restrict tool access, enforce least privilege, and apply automatic redaction before data can reach external services.
- Move AI checks into the SDLC Add adversarial probes, model access checks, and data-handling validation into build and release pipelines so unsafe AI paths are caught before production exposure.
Key takeaways
- Shadow AI is becoming a governance control problem because discovery without policy enforcement cannot stop data from moving into unsanctioned tools and agent workflows.
- Akto’s summary of Gartner’s report points to widening exposure from employee use of unsanctioned AI tools and from AI agents reaching external servers.
- The practical answer is identity-bound enforcement, governed gateways, and runtime validation, not discovery alone.

Key terms
- 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.
- Agentic workflow: An agentic workflow is a sequence of tasks executed by an AI agent with some level of tool access and decision authority. In security terms, the workflow matters because it can span multiple systems, identities, and permissions, which makes attribution and revocation harder than with ordinary automation.
- Identity-Aware Enforcement: Identity-aware enforcement is policy decisioning that uses who the user is and which account or context they are using. For browser AI, it helps distinguish sanctioned corporate use from unmanaged personal sessions and applies different controls based on that distinction.
- Governed Gateway: A governed gateway is a controlled path through which AI tools or agents must pass before they can reach data, APIs, or external services. It provides a decision point for least privilege, redaction, logging, and policy checks that periodic review cannot reliably deliver alone.
