Agent sprawl is what happens when agents spread across teams faster than an organization can track their owners, access, purpose and lifecycle. It is less a new organizational failure than a stress test for old ones: fragmented budgets, unclear accountability, shadow IT and weak coordination become more consequential when software can reach enterprise data and act across workflows.
What agent sprawl means—and what the numbers do and don’t say
An AI agent is software that can pursue a task using instructions, tools or data; the term covers a range of implementations, so counts depend on what an organization considers an agent and where it draws deployment boundaries. Sprawl is not simply having many agents. It is having more agents than the organization can identify, assign owners to, govern and retire responsibly.
Gartner forecast that the average global Fortune 500 enterprise will have over 150,000 agents in use by 2028, up from fewer than 15 in 2025. That is a forecast, not a census of agents currently running at each company. Gartner also reported that 13% of organizations think they have the right AI-agent governance in place; this is reported confidence, not an independent audit of governance quality. Gartner’s April 2026 announcement gives the context for both figures.

These are Microsoft-reported figures, not universal measures of enterprise adoption, and they should not be combined with Gartner’s forecast as if the sources measured the same thing. Microsoft Security explains its reporting and recommendations.

Why agent sprawl exposes existing organizational weaknesses
Ownership is unclear
A team may create an agent to solve a local problem without naming who is responsible for its access, maintenance, accuracy or retirement. When something changes or goes wrong, other teams may not know whom to contact—or even know the agent exists.
Inventory and shadow IT do not keep pace
Without a reliable inventory, leaders cannot answer basic questions: How many agents are running? Who owns each one? What information and tools can it reach? Is it approved, third-party or unsanctioned? This resembles older shadow-IT problems, but agents can make the consequences more immediate because they may act through connected systems rather than merely store information.
Identity and authorization become harder to manage
Human and service-account practices may not map neatly to agents that are created on demand, use multiple credentials, delegate authority or remain active after their original purpose ends. Each agent needs an identifiable owner and appropriately scoped permissions, with a process to revoke access when the agent changes or is retired. The Cloud Security Alliance’s 2026 note on agent identity sprawl describes these emerging authorization and lifecycle challenges and references NIST work in progress; it does not establish that a future standard is finalized.
Business units duplicate work and collide on shared data
Teams working independently may build agents that do the same job, or create agents that update shared records in conflicting ways. Separate efforts can also cross data or compliance boundaries without the teams realizing it. These are problems of coordination and data stewardship as much as model behavior. AWS describes these risks in multi-business-unit organizations.
Rank #3
Costs and business value are obscured
Small costs spread across teams can add up to substantial enterprise spending, while duplicated agents make it harder to see what capabilities the organization is paying for. If an agent has no defined workflow or expected outcome, leaders also lack a sound basis to judge whether it is useful, needs improvement or should be retired.
Governance and security solve different parts of the problem
Governance establishes who may create and share agents, who is accountable for them, what policies apply and how the organization oversees their lifecycle. Security enforces protections such as identity verification, least-privilege access, data controls and monitoring for misuse. An organization needs both: a policy without effective technical controls is hard to enforce, while controls without clear ownership leave responsibility unresolved.
That work typically crosses IT, security, legal, compliance, business leadership and the teams that build or use agents. Gartner analyst Max Goss warned that unmanaged agent growth can expose organizations to “misinformation, oversharing and data loss.” Gartner also argues for balancing governance with employees’ ability to innovate, rather than treating every agent as something to block. Gartner’s guidance and Microsoft Security’s governance and security recommendations both emphasize visibility and accountability.

Choose a governance model that fits the organization
| Consideration | Centralized governance | Federated hub-and-spoke governance |
|---|---|---|
| How it works | An enterprise team sets controls and coordinates agent deployments. | Enterprise-wide standards are paired with accountable leads in each business unit. |
| Consistency and visibility | Supports consistent controls and a coordinated enterprise view. | Requires shared standards and reporting so local activity is visible across units. |
| Local decision speed | Can limit local autonomy if every decision needs central approval. | Allows units to make decisions within enterprise guardrails. |
| Accountability | Responsibilities sit with a central governance function, alongside named owners for individual agents. | Enterprise oversight is shared with explicit local ownership in each participating unit. |
| Potential fit | May suit organizations that need tight, uniform oversight. | AWS presents a self-service-first federated model for many multi-unit organizations; stricter regulatory contexts may require permanent centralized governance. |
These are operating choices, not mutually exclusive technologies. The right design depends on regulatory obligations, shared systems and how much authority business units need. AWS’s practical principle is to make the governed route usable enough that teams do not bypass it. Gartner similarly cautions that simply blocking agents can push users toward shadow AI.

A practical sequence for bringing agent sprawl under control
- Build an inventory that includes the agents you do not approve. Create a centralized registry covering sanctioned, third-party and shadow agents. Record each agent’s purpose, accountable owner, business unit, tools and data it can access, permissions and lifecycle status. Visibility is the prerequisite for deciding what to govern.
- Assign identity and limit access. Establish who owns each agent and how its identity is verified. Apply least privilege, review the credentials and permissions it uses, and remove access that is no longer necessary. Microsoft recommends applying Zero Trust principles to agents; the Cloud Security Alliance highlights the need to manage identity throughout an agent’s lifecycle.
- Set data boundaries and lifecycle checks. Decide what information an agent may access and keep those permissions current. Monitor behavior, review whether the agent still serves its intended purpose, and retire redundant or obsolete agents rather than leaving them active without oversight.
- Coordinate activity across business units. Make local ownership explicit under the chosen governance model. Track duplicated capabilities, interactions with shared records, costs across unit budgets and relevant regulatory boundaries so one team’s deployment does not create an unseen problem for another.
- Connect deployment to an outcome. For each agent, identify the workflow it supports and the business result it is expected to deliver. Use monitoring to spot drift, misuse, duplicated effort or agents that no longer justify their cost; use those signals to adjust permissions, improve the agent or retire it.
These measures follow recommendations from Gartner, Microsoft Security, AWS and the Cloud Security Alliance. The sources include vendor guidance as well as industry analysis; the recommendations are operational controls, not proof that a single governance structure will fit every enterprise.
How to tell whether controls are working
Useful measures should show whether the organization can see and manage its agents, not just how many it has. Review whether the inventory has named owners and current access details; whether permissions match approved purposes; whether stale agents are removed; and whether teams can identify duplicated work, shared-data conflicts and aggregated costs. Pair those operational checks with the business outcomes assigned to each agent. A large inventory may be manageable if ownership and controls are clear; a small one can still be risky if nobody knows what its agents can do.
