Group-based access control is convenient specifically because a group bundles access into one reusable unit. That same convenience is exactly what causes group sprawl: it's easier to spin up a new group for a new situation than to check whether an existing one already covers it. A few years of that habit produces dozens of overlapping, half-documented groups nobody's sure they can safely delete.
Group sprawl is a distinct problem from access sprawl or identity sprawl. It's specifically about the groups themselves proliferating out of control: redundant groups covering the same population, groups created for a project that ended years ago and never cleaned up, groups whose original purpose nobody currently at the organization actually remembers.
Because groups are the mechanism many organizations use to grant access efficiently, sprawl in the groups themselves undermines the very efficiency that made group-based access attractive in the first place. This piece covers how that happens and how Zluri contains it.
At a glance, before the detail:
Why the Convenience of Groups Is Also the Cause of Group Sprawl
It's worth naming this tension directly, since it's the actual root of the problem.
Creating new is almost always faster than checking what exists. A new project, a new temporary need, a slightly different variant of an existing access pattern, spinning up a fresh group is almost always faster than the alternative: checking whether an existing group already covers most of what's needed and extending or reusing it instead.
Over time, that speed advantage compounds into real cost. An organization ends up with far more groups than it has genuinely distinct access patterns, many overlapping heavily with each other, some entirely redundant, and nobody with a clear enough picture of the whole landscape to know which ones can be safely consolidated or retired.
Seeing the Full Group Landscape Before Trying to Fix It
The first step in addressing group sprawl is having an accurate, complete picture of every group that actually exists, sourced from every connected identity provider rather than any single system's own, possibly incomplete, group console.
See every group in one place, not scattered across consoles. Zluri's Groups model surfaces this directly, with member count, source system, and combined spend and cost visible per group. This gives an admin trying to assess sprawl a genuine starting inventory, rather than having to manually reconcile group lists across Azure AD, Okta, Google Workspace, and whatever else happens to be connected.
Reviewing Whether a Group Should Still Exist, Not Just Who's In It
Ask whether the group itself still has a purpose, not just who's in it. A Groups-scoped Access Review asks a genuinely different question than a membership review does: not just "should this person still be in this group," but implicitly surfacing whether the group itself still has an active, meaningful membership and purpose at all.
A group review that keeps coming back nearly empty, or whose remaining members have no clear shared reason to be grouped together anymore, is exactly the signal that the group itself, not just its membership, has outlived its usefulness and is a candidate for retirement rather than ongoing individual membership cleanup.
Catching Redundant or Overlapping Groups
Group sprawl frequently manifests as near-duplicate groups: two groups covering almost the same population, created at different times by different admins who didn't know an equivalent already existed.
Compare group definitions and overlap across the full inventory. Two groups with heavily overlapping membership and near-identical downstream access are far easier to spot with a complete, centralized inventory in front of an admin than by trying to remember or manually cross-reference every group created across several different identity providers over several years.
Understanding What a Group Actually Costs Before Deciding to Keep It
Use cost as a prioritization signal, not a financial report. A group with very few active members but a meaningful associated cost is a stronger candidate for consolidation or retirement than one with a large, active membership. This isn't a substitute for accurate organization-wide financial totals, given the overlap that applies when someone belongs to multiple groups, but it's a useful signal for which groups in a sprawling landscape are actually worth reviewing first.
Automating Membership Instead of Manually Managing Group Sprawl's Symptoms
Part of what causes group sprawl in the first place is manual, ad hoc group management: someone manually adding people to whichever group seems closest to what's needed rather than following a defined, automated pattern.
Tie membership to attributes, not manual, case-by-case decisions. Joining a group as a direct consequence of a role or department attribute reduces the pressure that leads to creating a new group every time an existing one doesn't fit perfectly, since automated, attribute-driven membership handles more of the routine variation without needing a separate group for every minor difference.
Why Group Sprawl Needs Its Own Dedicated Cleanup Cadence
Because group sprawl accumulates specifically through the habit of creating new groups rather than reusing existing ones, addressing it requires more than folding it into a general access review. It needs a review cadence specifically asking "does this group still serve a distinct, active purpose" as its own question.
A recurring Groups-scoped review, treated as a standing practice rather than an occasional cleanup project, is what keeps the group landscape from silently sprawling back to its prior state the moment a one-time consolidation effort concludes.
Frequently Asked Questions
Is group sprawl the same thing as too many people having too much access?
No, that's access sprawl, a related but distinct problem covered separately. Group sprawl is specifically about the groups themselves proliferating, redundant, overlapping, or purposeless groups accumulating over time, independent of whether any individual person's access is actually excessive. For more on how this shows up specifically in Microsoft 365 and Teams environments, see what group sprawl looks like in practice.
Why does group-based access control tend to cause group sprawl if it isn't actively managed?
Because creating a new group for a new situation is almost always faster than checking whether an existing group already covers most of the need and reusing or extending it instead. That convenience, repeated many times over years by different people, produces far more groups than an organization has genuinely distinct access patterns.
How would an organization know if two groups are actually redundant with each other?
By comparing member overlap and source across the full group inventory in one place. Two groups with heavily overlapping membership, created independently by different admins who weren't aware of each other's group, are a common and specific pattern that becomes visible once the full group landscape is actually surfaced in one inventory rather than scattered across separate identity provider consoles.
Can automating group membership actually reduce how many new groups get created?
Indirectly, yes. When membership is driven by defined attributes, role, department, rather than manual, case-by-case decisions, there's less pressure to spin up a brand-new group every time an existing one doesn't perfectly fit a specific situation, since automated, rule-based membership already handles more of the routine variation an organization actually needs.
