TL;DR: Redundant SaaS apps create licensing waste, shadow IT, and fragmented control surfaces by letting teams adopt overlapping tools outside central visibility, according to Zluri. The bigger issue is that software sprawl also becomes identity sprawl, where access, renewals, and offboarding drift faster than governance can keep up.
At a glance
What this is: This is a 2026 guide on redundant SaaS apps, arguing that overlapping tools do more than waste money because they also widen shadow IT and weaken identity governance across discovery, renewal, and offboarding.
Why it matters: IAM, IGA, and SaaS management teams need to treat app sprawl as identity sprawl, because unmanaged overlap creates inconsistent access control, unclear ownership, and renewal drift across the software estate.
Context
Redundant SaaS apps are overlapping tools that perform the same or similar work, such as multiple project management, collaboration, or conferencing platforms inside one organisation. The governance problem is not only duplication of functionality, but duplication of access paths, renewals, and ownership decisions that are often made outside a central identity programme.
In practice, redundant apps create a wider control surface for shadow IT, fragmented license management, and inconsistent offboarding. When departments buy and renew software independently, identity governance loses visibility into who has access, which subscriptions are still live, and where review and revocation should happen first.
Key questions
Q: What breaks when redundant SaaS apps are not in central governance?
A: Redundant SaaS apps break ownership, access review, and offboarding because each tool can carry its own accounts, renewals, and integrations. Teams may think they are only duplicating functionality, but the real failure is that identity controls no longer cover the full software estate. The result is shadow IT with active access rather than harmless duplication.
Q: Why do overlapping SaaS apps create more risk than simple budget waste?
A: Because each extra application adds its own identity boundary, permission model, and offboarding path. That fragmentation weakens governance even when the tools appear harmless. The practical risk is that users keep access in forgotten systems long after the business has stopped relying on them.
Q: How should teams decide which redundant SaaS apps to remove first?
A: Start with apps that are low-usage, poorly owned, and already outside central governance. Those tools are usually the easiest to retire and the most likely to hide stale accounts or forgotten integrations. Then move to overlapping apps that carry the most sensitive data or the widest admin access.
Q: When should organisations treat a SaaS platform as an identity governance issue?
A: Whenever the platform mediates communication, recovery, delegated access, or machine-to-machine activity across many users or tenants. At that point, the platform is no longer just an application. It is part of the identity fabric, and its support paths, tokens, and trust relationships need lifecycle governance.
Technical breakdown
How redundant SaaS apps create identity sprawl
Redundant SaaS apps do not just duplicate workflows. They duplicate entitlement models, admin roles, user accounts, OAuth grants, and renewal relationships across tools that were never intended to be governed as one estate. That creates identity sprawl because every extra app adds another access boundary, another lifecycle process, and another place where visibility can break down. In a decentralised purchasing model, the organisation may know the applications exist without knowing who owns the access model behind them.
Practical implication: treat app rationalisation as an identity inventory problem, not only a procurement exercise.
Why shadow IT becomes a governance issue, not just a buying issue
Shadow IT emerges when teams adopt software outside central approval, but the governance consequence is deeper than contract waste. Unauthorized apps often carry live user access, shared accounts, embedded tokens, and undocumented integrations that sit outside normal joiner, mover, leaver processes. Once those tools are in use, security teams lose confidence that access review, approval, and offboarding are complete. The result is a parallel control plane that behaves like sanctioned IT while escaping governance controls.
Practical implication: map unsanctioned apps to the identities and integrations they actually use before you attempt to remove them.
Why renewals and offboarding fail in a redundant SaaS estate
Redundant SaaS environments tend to survive because renewal decisions happen on a different cadence from access governance. A subscription can auto-renew even when usage is low, ownership is unclear, or the original business case no longer exists. Offboarding fails for the same reason: when nobody formally owns the app, nobody confirms that user access, admin rights, and integrations are removed together. This is where SaaS waste becomes governance debt, because the organisation keeps paying for software that still holds active identity relationships.
Practical implication: tie renewal review to ownership, usage, and access certification in the same control workflow.
Threat narrative
Attacker objective: The practical objective is to preserve access and reach through unmanaged SaaS control points long enough to avoid detection and governance cleanup.
- Entry occurs when departments independently adopt overlapping SaaS tools without central visibility, creating unmanaged apps and unsanctioned access paths.
- Credential and access sprawl follows as each tool introduces its own users, admin roles, and sometimes shadow integrations outside formal governance.
- Escalation occurs when redundant subscriptions and forgotten accounts remain active, giving unused tools persistent access and complicating revocation.
- Impact is fragmented governance, higher security exposure, and wasted spend across a SaaS estate that no longer reflects actual business need.

NHI Mgmt Group analysis
Redundant SaaS apps are an identity governance problem before they are a cost problem: once overlapping tools proliferate, the organisation has multiple entitlement models, renewal states, and ownership records to govern. That fragmentation makes joiner, mover, leaver processes harder to complete consistently, especially where departments buy software independently. The practitioner conclusion is simple: app consolidation is an identity control decision, not only a budgeting exercise.
Shadow IT becomes more dangerous when it carries live access rather than mere software waste: unauthorized SaaS does not just bypass procurement, it bypasses access review, offboarding, and integration oversight. The governance gap is the absence of a reliable inventory of which apps exist and which identities they trust. The practitioner implication is that governance teams need app-to-identity visibility before they can claim control over the stack.
Identity sprawl is the right name for what redundant SaaS creates: each extra tool adds another set of accounts, renewal obligations, admin privileges, and embedded connections that can outlive the business purpose of the app. That means renewal management and access governance are the same control problem viewed from different angles. Practitioners should treat every extra SaaS contract as a lifecycle commitment, not a simple software purchase.
Access governance fails when application ownership is diffuse: auto-renewals, departmental subscriptions, and low-usage licences often persist because no one is accountable for the whole lifecycle. The deeper issue is not a missing checkbox but a broken operating model where review, revocation, and spend control are separated. The practitioner conclusion is to align ownership, usage evidence, and offboarding authority around a single accountable control path.
Redundant SaaS exposes a control assumption that the software estate is knowable from procurement records alone: that assumption fails when teams can independently adopt cloud applications, create accounts, and connect integrations without central oversight. The implication is that SaaS governance must be built on discovered usage and trusted ownership, not on purchasing data alone.
From our research library:
- The average enterprise SaaS platform connects to 42 or more third-party applications through OAuth tokens, API keys, webhooks and automation platforms.
What this signals
Identity sprawl is the hidden cost of redundant SaaS: every overlapping application adds another account set, another renewal decision, and another offboarding event that can drift away from governance. For security and IAM teams, the signal is that software rationalisation and access lifecycle management now have to move together, or neither stays effective.
Redundant SaaS weakens the assumption that procurement visibility equals control: in cloud estates, departments can buy or trial tools faster than central teams can catalogue them. The practical implication is that governance must start from discovered usage, because app inventories built only from purchasing records will always lag the real estate.
SaaS renewal is becoming an identity control checkpoint: when unused tools auto-renew, the organisation is effectively paying to keep dormant access paths alive. IAM and IGA teams should use renewal events as a trigger for ownership review, entitlement certification, and cancellation decisions where the business no longer needs the app.
For practitioners
- Discover the full SaaS estate Build an application inventory from departmental usage, not just procurement records, and identify every overlapping tool by function, owner, and business purpose.
- Tie renewals to access evidence Require usage data, ownership confirmation, and access review before any auto-renewal is approved so redundant subscriptions cannot persist by default.
- Rationalise overlapping tools by function Compare tools that serve the same workflow, then consolidate on the smallest approved set that still meets business requirements and governance needs.
- Review shadow apps for identity exposure Check whether unsanctioned tools hold active user accounts, admin roles, OAuth grants, or integrations that would survive if the subscription were cancelled.
- Align offboarding with contract closure Remove access, integrations, and admin rights at the same time you terminate the app relationship so dormant SaaS cannot remain reachable.
Key takeaways
- Redundant SaaS apps are a governance issue because they multiply identities, renewals, and ownership paths across the software estate.
- The article’s core warning is that shadow IT and software waste are linked to access drift, not just to procurement inefficiency.
- The control gap is not only discovery. It is the absence of a lifecycle process that ties app ownership, entitlement review, and offboarding to renewal decisions.

Key terms
- Redundant SaaS App: A redundant SaaS app is a tool that duplicates the function of another application already in use by the organisation. The governance issue is not only cost duplication, but the extra identities, permissions, and integrations that have to be reviewed, retired, and secured across both systems.
- Shadow IT: Shadow IT is the use of applications or services outside formal enterprise approval or visibility. In SaaS environments, it often includes department-purchased tools and unsanctioned integrations that create hidden identity, data, and access paths the security team cannot readily govern.
- Identity Sprawl: Identity sprawl is the uncontrolled growth of identities, entitlements, and credentials across an environment. For NHIs, it usually appears when automation creates accounts faster than governance teams can inventory, review, and remove them. The result is hidden access, weak accountability, and a wider attack surface.
- SaaS Lifecycle Governance: SaaS lifecycle governance is the set of controls that manage applications from onboarding through access assignment, renewal, and decommissioning. It matters because the security value of SaaS management depends on whether the organisation can prove ownership, revoke access, and retire unused tools on demand.
