TL;DR: SAM risk should be prioritised by combining vendor risk and usage volume, with discovery, renewals, and vendor management used to reduce compliance exposure and software waste, according to Zluri. The governance gap is that software sprawl is an identity and access problem as much as an asset problem, because unmanaged SaaS often means unmanaged accounts, permissions, and renewal obligations.
At a glance
What this is: This is a SAM prioritisation framework that ranks SaaS risk by vendor risk and usage volume, with the key finding that software sprawl becomes an identity governance problem when accounts, permissions, and renewals are not controlled together.
Why it matters: IAM, IGA, and SaaS governance teams need this lens because unmanaged applications often create unmanaged access paths, renewal exposure, and orphaned entitlements across the software estate.
Context
SaaS risk is not only a procurement or licence-cost problem. Once an application is widely adopted, the governance challenge expands into identity lifecycle, account ownership, permission scope, and renewal control, which means software sprawl can outgrow a purely asset-management view.
The article’s core argument is that SAM teams need to prioritise risks by both risk and volume, not by licence count alone. That matters for identity programmes because the same sprawl that drives overspend often also creates unmanaged users, unclear ownership, and weak offboarding discipline.
Key questions
Q: How should teams prioritise SaaS applications for risk review?
A: Prioritise applications by combining business criticality with exposure volume. High-risk, high-volume tools deserve the fastest review cycles because they create the broadest compliance and access impact. Lower-volume specialist tools still matter when they carry privileged functions, sensitive data, or expensive audit penalties. A simple quadrant model helps teams focus governance effort where failure would hurt most.
Q: Why do SaaS sprawl and identity governance fail in the same place?
A: They both depend on discovery happening before control. If applications are only found at purchase or SSO integration, finance cannot manage spend early and security cannot govern access early. The shared failure is late visibility, which turns both disciplines into cleanup functions instead of preventive ones.
Q: What do organisations get wrong about SAM renewals?
A: They treat renewals as a contract event instead of a governance checkpoint. Renewal decisions should confirm active use, access legitimacy, and owner accountability, otherwise dormant entitlements and unnecessary applications can persist for another term.
Q: How can teams tell whether SaaS governance is actually working?
A: Look for evidence that discovered applications can be assigned an owner, tied to an access policy, and removed through an enforced workflow. If the platform can only report on SaaS usage but cannot drive deprovisioning or entitlement review, governance is still fragmented.
Technical breakdown
How a 2x2 risk and volume matrix changes SAM prioritisation
The article uses a 2x2 matrix to classify software vendors by risk and usage volume, then prioritise response by quadrant. High risk and high volume demands different treatment from low volume, high risk software, because scale changes the blast radius of non-compliance, audit exposure, and operational disruption. That approach is useful when software estates contain both widely used collaboration tools and niche, expensive platforms with complex licensing terms. The key technical point is that prioritisation becomes a governance decision, not just an inventory exercise.
Practical implication: separate high-volume software governance from high-risk niche software governance so remediation follows exposure, not just licence counts.
Why SaaS sprawl becomes an identity governance issue
Software asset management usually starts with licences, but SaaS environments also carry identities, access entitlements, and delegated administration. If an application is not owned, reviewed, and offboarded properly, the organisation can lose track of who still has access and which permissions remain active after a business need changes. That is why SAM and IGA overlap in practice: application inventory without identity ownership leaves a control gap at the point where users, admins, and renewals intersect. The risk is governance fragmentation, not just overspend.
Practical implication: map each material SaaS application to an owner, an access path, and a renewal decision point.
What vendor audit exposure really signals in SaaS estates
The article highlights the risk of discrepancies between purchased licences, employee count, and actual usage. In practice, those mismatches are audit signals that often point to shadow SaaS adoption, untracked renewals, or access granted outside formal procurement routes. The governance problem is not only whether the software is paid for, but whether the organisation can explain its usage, ownership, and entitlement history under scrutiny. For identity teams, that means software governance data and access governance data should be reconcilable.
Practical implication: reconcile usage, procurement, and access records before a vendor audit exposes gaps in control ownership.
NHI Mgmt Group analysis
SaaS sprawl is an identity governance problem disguised as SAM. The article treats risk as a software management issue, but unmanaged SaaS almost always means unmanaged access, unclear ownership, and incomplete offboarding. Once application sprawl reaches that point, licence control and access control are the same governance problem seen from different angles. Practitioners should stop treating SaaS inventory as a separate admin task and govern it as part of identity lifecycle.
Risk prioritisation should follow exposure, not software category labels. High-risk, high-volume applications deserve different governance than low-volume, niche tools because the likely failure modes are different. One quadrant creates audit and compliance concentration, while another creates expensive but contained non-compliance. The useful decision is not whether SAM matters, but which combinations of business criticality and usage intensity deserve the earliest control attention.
Identity blind spots in SaaS renewals create hidden entitlement drift: renewal decisions are often made without a clear view of who is still using the application, who owns the access path, and whether the business need still exists. That creates entitlement drift even when the licence is technically paid for. Practitioners should treat renewals as a governance checkpoint for access validity, not just a commercial negotiation.
Vendor audit readiness depends on joining procurement and identity data. The article’s examples around licence discrepancies and usage tracking show that audit defence fails when teams cannot reconcile procurement records with real application usage. That is not simply a finance control gap. It is a cross-functional governance failure that identity, IT, and procurement teams have to share, because the evidence trail crosses all three.

What this signals
Identity ownership is the missing layer in many SAM programmes: software inventories only become governable when each application has a clear owner for access, renewals, and offboarding. Without that layer, the organisation can measure spend but still fail to control who can actually use the software.
SaaS renewal cycles should be treated as entitlement reviews: a renewal is the right moment to confirm whether access is still justified, whether the application still has a business purpose, and whether dormant users can be removed before the next term begins.
For practitioners
- Prioritise SaaS by risk and usage volume Classify applications into a risk-volume matrix so governance effort goes first to tools with both high exposure and broad adoption. Use this view to distinguish audit-heavy platforms from niche but expensive software.
- Tie every material app to an owner Assign an accountable business and technical owner for each SaaS application so renewals, access decisions, and offboarding do not drift between teams. Ownership must include who approves continued use and who can revoke access.
- Reconcile usage, licence, and employee records Compare actual active usage against purchased licences and workforce counts to identify oversubscription, dormant entitlements, and unapproved adoption. This is the fastest way to surface hidden governance gaps before an audit does.
- Review renewals as access checkpoints Use each renewal cycle to confirm whether the application still has a business purpose, whether access is still justified, and whether inactive users can be removed. Renewal timing should trigger a governance review, not just a finance approval.
Key takeaways
- SaaS sprawl is not only a licence efficiency issue. It becomes a governance problem when applications outgrow clear ownership, access review, and offboarding.
- The article’s prioritisation model is useful because it combines risk with usage volume, which better reflects real audit and operational exposure than inventory alone.
- Identity teams should align procurement, usage, and access records so renewal decisions and SAM reviews expose drift before it becomes a compliance problem.

Key terms
- SaaS Sprawl: SaaS sprawl is the uncontrolled spread of software-as-a-service applications across teams and business units. It creates fragmented ownership, duplicated functionality, and weak visibility into who can access what. For IAM and NHI teams, the main risk is not only cost but persistent entitlements that outlive business need.
- SAM Risk Prioritisation: SAM risk prioritisation is the process of ranking software asset management issues by exposure and business impact. In practice, it helps teams decide which applications need immediate attention, using factors such as usage volume, licence sensitivity, audit risk, and operational criticality.
- Entitlement Drift: Entitlement drift is the slow accumulation of permissions that no longer match the original purpose, role, or workload. In cloud-native and NHI-heavy environments, it usually happens because access changes faster than review cycles, leaving organizations with more privilege than they intended.
- Application Ownership: Application ownership is the assignment of accountability for approving, funding, governing, and retiring a software application. Effective ownership links budget responsibility to access responsibility, which is essential when renewals, offboarding, and access reviews need a clear decision-maker.
