Groups exist to make access management simpler: bundle a set of permissions once, then add and remove people from that bundle instead of managing each permission individually. Group sprawl is what happens when creating a new bundle becomes easier than checking whether one already exists.
Group sprawl is the uncontrolled, unplanned growth of groups or teams within an organization's digital workspace. It shows up most often on platforms like Microsoft 365 and Microsoft Teams, where creating a new group takes seconds and requires no coordination with anyone else.
When departments and teams create their own groups independently, without checking what already exists, the result is a landscape of disconnected, often redundant groups. This isn't a hypothetical risk. It's the default outcome of making group creation easy and group governance an afterthought, and it leads directly to confusion, ownership gaps, and real security exposure.
What Group Sprawl Actually Looks Like
Picture an organization running project collaboration through Microsoft Teams. Different departments and project teams each have the freedom to create their own Teams or groups, and most of them do, without considering whether something similar already exists elsewhere in the organization. The result is a proliferation of Teams, many serving overlapping purposes or no clear purpose at all.
The ease of creating and deploying new Teams, 365 Groups, and SharePoint sites is a major contributor here. Remote work and heavier reliance on collaboration tools only accelerate it: teams can spin up groups without involving central IT, which speeds up adoption in the moment but means losing control over new group creation across the organization, sometimes producing thousands of scattered groups across a single tenant.
Group membership decisions carry real access control weight, even when they don't feel like it in the moment. Every group creation and membership decision implicitly answers four questions that carry genuine security implications: who should have access, how that access gets granted, what scope and duration is appropriate, and why the access is justified in the first place. When group creation happens ad hoc, none of these questions gets a deliberate answer, which is exactly why IT teams struggling with sprawl also tend to struggle explaining why any given group exists or what access it was actually meant to control.
What Drives Group Sprawl
A handful of specific factors reliably produce it:
Self-service provisioning. Most SaaS applications let users create groups or teams without administrative oversight, which is convenient in the moment and unchecked in aggregate.
Lack of governance policies. Without clear guidelines on when and how to create a group, people create them inconsistently or unnecessarily, since there's no shared standard to follow.
Organizational structure changes. Mergers, acquisitions, and departmental reorganizations reliably produce new groups or duplicate existing ones, since restructuring rarely comes with a parallel cleanup of the groups it makes obsolete.
Shadow IT. Groups created in unsanctioned platforms, to work around official channels, scatter collaboration efforts even further and stay invisible to whatever governance process exists.
Limited visibility and control. Without a clear picture of existing groups and their purposes, administrators simply can't govern what they can't see, which makes sprawl self-perpetuating.
Underutilized features. People frequently create a new group for something an existing group could already handle, usually because they're unaware the existing option covers their need.
Individual habits. Some people default to creating a new group for every project or task as a matter of personal working style, regardless of whether that matches organizational practice.
The Consequences of Letting Group Sprawl Run
A cluttered, harder-to-navigate workspace. With teams and groups created independently and inconsistently, finding relevant information becomes genuinely difficult, and users waste real time navigating a landscape nobody organized on purpose.
Fragmented information. Resources and discussions end up spread across near-duplicate groups instead of consolidated in one place, creating information silos that actively work against the collaboration groups were meant to enable.
Ownership ambiguity. Ad hoc group creation means it's often unclear who's actually responsible for a given group, which creates real friction around decision-making, accountability, and day-to-day management.
Security exposure. This is the consequence that matters most. Unmonitored, redundant groups are exactly where sensitive information ends up inadequately protected, since nobody's actively governing access through a group nobody remembers creating.
How to Actually Identify and Reduce Group Sprawl
Establish real governance policies. Clear guidelines for when and how groups should be created give the organization a shared standard to create against, rather than leaving every team to invent its own convention.
Run regular audits. Periodically assessing the full landscape of groups, identifying which ones are redundant or underutilized, is what actually surfaces consolidation and removal candidates. Sprawl accumulates precisely in the gaps between these audits, which is why the cadence matters as much as the audit itself.
Use automation for the group lifecycle. Automating creation, management, and monitoring keeps governance policy consistently applied and meaningfully reduces the manual burden that makes ad hoc group creation the path of least resistance in the first place.
Centralize how access requests get approved. A structured, centralized process for reviewing and approving group creation prevents spontaneous, uncoordinated growth by default, ensuring new groups actually align with organizational objectives rather than duplicating something that already exists.
Where This Connects to the Rest of Your Access Landscape
Group sprawl doesn't stay contained to groups. A bloated, redundant group structure makes access sprawl meaningfully harder to reason about, since reviewing what someone actually has access to means tracing it across however many overlapping groups they happen to belong to, rather than a clean, rationalized set. And group sprawl frequently compounds identity sprawl too, since duplicate or shadow groups are often created against duplicate or shadow identity records that were never reconciled in the first place.
For the specific mechanics behind fixing this, seeing every group across every connected identity provider in one place, reviewing whether a group itself still has a purpose rather than just who's in it, and catching near-duplicate groups before they become permanent, see how Zluri contains group sprawl. And for how this fits alongside every other type of sprawl an organization deals with, see managing every type of sprawl with one framework.
Frequently Asked Questions
What is group sprawl?
Group sprawl is the uncontrolled, unplanned growth of groups or teams within an organization's digital workspace, most commonly seen on platforms like Microsoft 365 and Teams, where creating a new group requires no coordination with anyone else.
How is group sprawl different from access sprawl?
Access sprawl is about how much any single identity can do, permissions accumulating over an identity's tenure. Group sprawl is about the groups themselves proliferating, independent of whether any individual person's access is excessive. The two compound each other, since a sprawling group structure makes it far harder to reason accurately about anyone's actual access.
Why does self-service group creation lead to sprawl if it isn't actively governed?
Because creating a new group is almost always faster than checking whether an existing one already covers the need. Repeated across many people and many years, that speed advantage produces far more groups than the organization has genuinely distinct access patterns to justify.
What's the biggest risk of unmanaged group sprawl?
Security exposure. Unmonitored, redundant groups are exactly where sensitive data and access end up inadequately protected, since nobody is actively governing access granted through a group whose purpose and ownership nobody currently remembers.
How often should an organization audit its groups?
Regularly and on a defined cadence, not as a one-time cleanup project. Sprawl accumulates continuously between audits as new groups get created, so a periodic review that isn't repeated on a standing schedule will simply let the same problem rebuild after each cleanup concludes.
