TL;DR: Enterprises are adding AI agents and cloud apps faster than legacy IGA can govern them, expanding the attack surface and audit burden under GDPR, NIS2 and DORA, according to Omada Identity. The core issue is that access review and lifecycle processes assume identities are stable enough to be reviewed, but AI-driven execution makes that assumption fragile.
At a glance
What this is: This is an analysis of how AI agents and cloud app sprawl are stretching legacy identity governance, with the central finding that review and lifecycle processes no longer fit the speed and scope of non-human access.
Why it matters: IAM, IGA and PAM teams need to treat AI agents as governed identities, because the access they hold, the data they touch and the pace of change they introduce can outstrip human-centric controls.
By the numbers:
- 72% of CIO participants noted that app sprawl was concerning.
Context
AI agent governance and non-human identity sprawl are becoming a single IAM problem because organisations are now assigning machine-driven workflows access to business systems, data and approvals. That shifts identity governance from a largely human lifecycle model to one that must account for non-human identities that act, request and retain permissions at machine speed.
Legacy IGA models assume identities are relatively stable, reviewable and easy to map to business roles. Once AI agents and cloud apps are added at scale, those assumptions weaken, and the result is more access to govern, more audit pressure and more need for lifecycle automation, recertification and role-based control.
The article argues that the issue is not just the number of identities. It is the mismatch between old governance rhythms and the pace at which AI-enabled systems now consume, change and exercise access across environments.
Key questions
Q: How should teams govern non-human identities in AI-heavy environments?
A: Teams should govern non-human identities the same way they govern other privileged assets: assign ownership, minimise scope, rotate credentials regularly, and monitor for abnormal use. The key difference is speed. AI-driven workflows can exploit exposed access quickly, so detection and revocation must be automated and tied to lifecycle controls.
Q: Why do AI agents make legacy IGA harder to operate?
A: AI agents increase the number of identities, the pace of change and the number of systems that must be reviewed. Legacy IGA often assumes slower, more predictable access lifecycles, so the governance burden rises when entitlements change faster than manual review cycles can keep up.
Q: What are the signs that non-human identity governance is starting to slip?
A: Warning signs include reliance on manual upgrade paths, ad hoc secret handling, and fragmented access management across tools and environments. The article mentions caveats, dispatch limits, SSO support, and automated update channels, all of which point to the need for controlled operational discipline. When teams cannot explain how identities are provisioned, updated, and constrained, governance is already weaker than it should be.
Q: When should organisations prioritise automation over manual review for NHI governance?
A: Automation should be prioritised when access volume, agent activity or application sprawl makes manual review too slow to be reliable. If a non-human identity can change state faster than the review cycle can observe it, the control belongs in issuance and monitoring rather than in the spreadsheet.
Technical breakdown
Why AI agents expose legacy IGA assumptions
Legacy IGA was designed around identities that have a stable owner, a predictable role and a review cycle long enough for governance to catch up. AI agents break that model when they operate as non-human identities inside workflows, because access can be created, used and expanded faster than manual approval or periodic certification can track. The governance problem is therefore not just volume, but tempo. When an identity can act across systems at machine speed, lifecycle and recertification processes have to move from retrospective validation toward controlled issuance and continuous policy enforcement.
Practical implication: map where your current IGA process still assumes slow, human-paced identity change and identify the non-human workflows that already exceed it.
Role-based controls for non-human identity access
Role-based access control remains relevant, but it has to be applied more strictly to non-human identities than many teams have historically done. The article points out that different AI agents may need very different scopes, such as scheduling data, financial records or code repositories, and a broad entitlement model creates unnecessary exposure. In machine identity terms, the control issue is authorised behaviour, not just authentication. If access is granted by default or at a broad application layer, the identity can traverse data boundaries that were never intended for that workflow.
Practical implication: define non-human roles by task and data boundary, then review whether any agent can reach systems outside its business function.
Why automation becomes a governance control, not just an efficiency gain
The article treats automation as a governance necessity because manual recertification, onboarding and offboarding do not scale with AI agents and app sprawl. Automation matters most where access requests, anomaly handling and remediation need to be tied together across IGA and security tools. That is also why the piece emphasizes integration with security tooling: if identity signals and threat signals stay separate, response remains too slow. Modern IGA for NHIs is therefore as much about enforcement speed as it is about administrative convenience.
Practical implication: connect identity governance workflows to security telemetry so access changes and anomaly response can happen in the same control plane.
Threat narrative
Attacker objective: The objective is to exploit overextended non-human access to reach sensitive systems and data while governance is too slow to constrain it.
- Entry occurs when AI agents and cloud applications are introduced into business workflows with broad, loosely governed access.
- Credential and entitlement exposure follows when those non-human identities are given permissions that exceed their task scope or are not recertified quickly enough.
- Impact emerges as the expanded attack surface drives audit pressure, data leakage risk and compliance failures across regulated environments.

NHI Mgmt Group analysis
AI agent governance is becoming the test case for whether legacy IGA can survive non-human scale. The article is right to frame AI agents and cloud apps as a governance problem, not just an automation trend. Once agents are allowed to hold and use access across systems, the old assumption that identity review is tied to stable human employment cycles stops holding. The implication is that IGA programmes now have to govern execution-bearing identities, not just users.
App sprawl and NHI sprawl are the same control problem expressed at different layers. More SaaS creates more access relationships, and AI agents multiply the number of identities that can act inside them. That makes role modelling, lifecycle automation and entitlement review inseparable from application rationalisation. Practitioners should treat access sprawl and identity sprawl as one programme issue, not two separate backlogs.
Role-based control is still useful, but only if it is made precise enough for machine behaviour. The article correctly argues that carte-blanche access is neither sustainable nor secure for AI agents. In practice, this means the business role has to be translated into narrow, auditable task scope, or the resulting access model becomes impossible to govern at audit time.
AI can assist identity governance, but it cannot be allowed to excuse weak governance design. The article highlights anomaly detection, reporting and faster decisions, which are legitimate uses of AI in IGA. But those benefits only matter if the underlying identity model is already sound. Otherwise AI simply helps scale a broken entitlement structure faster than before.
Legacy machine IAM lags because most programmes still govern non-human identities as if they were exceptional accounts. Gartner’s observation, cited in the article, aligns with what we see operationally: NHIs are now part of core business execution. The practical implication is that machine identity governance needs its own operating rhythm, its own recertification logic and its own enforcement model.
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.
- 59% of organisations say they lack viable alternatives to standing privileged access for NHIs and AI agents, according to Delinea research.

What this signals
Machine identity governance is moving from a specialist concern to an operating model question. Once AI agents and cloud apps start consuming access at scale, the issue is no longer whether a team has an IGA tool. The issue is whether identity governance can keep pace with non-human execution, ownership and review across systems.
Role modelling now has to account for agent behaviour, not just entitlements. A task-scoped access model is only useful if the organisation can actually distinguish one agent’s business purpose from another’s. That makes clean ownership, narrow authorisation and governance reporting core controls, not administrative polish.
For practitioners
- Map AI agents as governed non-human identities Inventory which agents, bots, service accounts and application keys already hold production access, then assign each one an owner, business purpose and lifecycle status.
- Tighten role scope around agent tasks Break broad application access into task-specific roles so each agent only reaches the data and systems needed for its function.
- Automate recertification for machine access Move recurring access reviews for non-human identities into automated workflows that can validate role, purpose and entitlement changes at scale.
- Connect IGA to security telemetry Integrate identity governance with detection and response tooling so anomalous access can trigger alerts or access shutdown without manual delay.
- Separate human and machine governance reporting Track non-human identity growth, review completion and role drift in reporting that distinguishes machine access from human access for audit readiness.
Key takeaways
- AI agents and cloud apps are turning non-human identity governance into a core IGA problem rather than a niche machine-account issue.
- The main risk is not just identity volume, but the mismatch between fast-moving non-human access and slower review and lifecycle processes.
- Organisations need task-scoped roles, automation and security integration to govern agents with enough precision for audit and operational control.

Key terms
- Non-Human Identity (NHI): A digital identity assigned to a non-human entity such as a software application, service account, API key, bot, machine, or AI agent that enables it to authenticate and interact with systems without direct human involvement. NHIs now outnumber human identities in most enterprises by 25 to 50 times.
- Identity Governance and Administration (IGA): A framework of policies, processes, and technology to manage and govern digital identities and their access rights. Increasingly extended to cover non-human identities alongside human users.
- App Sprawl: App sprawl is the rapid growth in the number of SaaS and cloud applications an organisation must manage. It increases complexity because each app brings its own permissions, access paths, and lifecycle needs, making manual governance harder and creating more places for security blind spots to emerge.
- Access Recertification: Access recertification is the periodic review of user or account permissions to confirm that access is still justified. It is useful, but it is not enough on its own because it reacts after entitlements already exist, which is why lifecycle governance must reduce the volume of exceptions before review time.
