TL;DR: Software evaluation checklists help teams compare functionality, cost, and stakeholder fit, but they also reveal a broader governance problem: SaaS buying decisions often outpace identity, access, and lifecycle controls, according to Zluri. Procurement discipline matters, but identity teams still need to govern who gets access, how it is reviewed, and when it is removed.
At a glance
What this is: This is a SaaS procurement checklist article that argues structured evaluation reduces decision friction, but it also exposes how purchasing processes can outpace identity and access governance.
Why it matters: It matters because SaaS selection affects access sprawl, stakeholder approval paths, and lifecycle controls across human users, service accounts, and the systems that connect them.

Context
SaaS evaluation is not just a procurement exercise. It is an identity governance decision because every new application introduces users, administrators, integrations, and lifecycle obligations that eventually have to be reviewed, revoked, and defended.
The article focuses on functional fit, cost, stakeholder agreement, and vendor comparison. From an IAM perspective, the deeper issue is whether buying decisions create access paths faster than teams can govern them, especially when applications introduce new human accounts, machine accounts, and delegated integrations.
Key questions
Q: How should IAM teams govern SaaS purchases before rollout?
A: IAM teams should treat SaaS purchasing as a control checkpoint, not a post-contract cleanup exercise. Before rollout, they should confirm federation, role design, privileged access, integration ownership, and offboarding paths. That prevents business demand from creating unmanaged access paths and makes the application governable from day one.
Q: Why do SaaS buying decisions create access governance risk?
A: SaaS buying decisions create risk because each new application adds identities, permissions, and integrations that must be managed over time. If procurement happens without IAM input, teams usually discover the control gaps after users are already active. That leads to entitlement sprawl, unclear ownership, and delayed deprovisioning.
Q: What do organisations get wrong about total cost of ownership for SaaS?
A: Organisations often count licence fees and deployment work but ignore recurring identity work. Access reviews, admin oversight, entitlement cleanup, and offboarding effort are part of the real cost. If those costs are excluded, a cheap application can become expensive to govern and difficult to retire cleanly.
Q: Who should approve SaaS tools from an identity perspective?
A: SaaS tools should be approved by business stakeholders, IT, security, and the application owner together. Business approval confirms value, but identity approval confirms that access can be provisioned, reviewed, and removed safely. Without that shared decision, the organisation inherits an application it cannot fully govern.
Technical breakdown
Why SaaS evaluation creates identity sprawl
Every new SaaS application expands the identity surface. A single purchase can create human user access, admin entitlements, API connections, service accounts, and SSO trust relationships. If evaluation focuses only on features and price, teams miss the operational cost of provisioning, access reviews, recertification, and offboarding. The problem is not software selection itself, but the hidden governance work that follows adoption. Once the app is live, identity controls must cover who can use it, which systems can talk to it, and how those rights are removed when the relationship changes.
Practical implication: include identity inventory, lifecycle ownership, and offboarding requirements in every SaaS evaluation.
How procurement decisions affect access governance
Procurement often decides the application before IAM has defined the control model. That creates a gap between commercial approval and security readiness. If stakeholders choose tools without mapping authentication, federation, admin roles, and integration permissions, the result is ad hoc access design after deployment. In practice, that leads to over-permissioned admins, unmanaged shared accounts, and unclear ownership of integrations. The evaluation checklist should therefore be read as a governance input, not only a buying template. The technical question is whether the chosen application fits existing identity architecture or forces exceptions that accumulate over time.
Practical implication: require IAM sign-off on federation, role design, and integration permissions before SaaS contract approval.
What total cost of ownership misses in identity programmes
The article treats total cost of ownership as purchase price plus implementation, support, and replacement. For identity teams, that is still incomplete. SaaS ownership also includes entitlement review effort, joiner-mover-leaver processing, admin delegation, logging, and the risk cost of dormant or orphaned access. A low-cost application can become expensive if it multiplies exceptions across HR, finance, and IT workflows. The technical takeaway is that access governance overhead should be counted as part of operational ownership, not as a separate security project after the fact.
Practical implication: add access governance, recertification, and offboarding effort to TCO calculations for every SaaS purchase.
NHI Mgmt Group analysis
SaaS procurement is an identity governance event, not a buying event. Every application purchase creates a new access boundary, new administrative trust, and new lifecycle work. The article is useful because it shows how quickly business selection criteria can outrun IAM controls if identity ownership is not built into the evaluation step. Practitioners should treat procurement intake as the first control point in SaaS governance.
Access sprawl starts before the first login. Once stakeholders approve a SaaS tool, identity teams inherit the consequences: federation setup, role mapping, privileged access, and offboarding obligations. The governance failure is not in user adoption alone. It is in allowing commercial approval to occur without a defined identity model for the application. That is where entitlement creep begins, and practitioners should make that boundary explicit.
Total cost of ownership is incomplete without identity lifecycle cost. The article correctly notes implementation and support, but it underestimates the burden of access reviews, admin review, and orphaned account cleanup. In modern SaaS estates, identity work is recurring operational overhead, not a one-time setup task. Organisations that ignore that cost tend to underfund governance and overestimate the true value of the application.
Stakeholder alignment must include control owners, not only buyers. Business departments can validate usefulness, but they cannot by themselves define access architecture, federation trust, or offboarding standards. The evaluation process should force agreement between procurement, IT, security, and application owners before contracts are signed. That is the point at which SaaS decisions become governable rather than merely approved, and practitioners should make that distinction routine.
From our research:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to Ultimate Guide to NHIs.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
- For a deeper baseline on governance scope, see Ultimate Guide to NHIs for the broader lifecycle and control model.
What this signals
SaaS procurement is becoming a governance control point, not just a buying workflow. Teams that do not require identity sign-off early will keep discovering access design flaws after deployment, when remediation is slower and more expensive.
Lifecycle debt: the real risk is not the app itself but the accumulation of unresolved ownership, admin privilege, and offboarding work. In practice, that means procurement teams and IAM teams need a shared approval path before new tools enter the estate.
The broader signal is that application rationalisation, access review, and deprovisioning need to be evaluated together. When SaaS growth outruns identity controls, the programme spends more time catching up than governing.
For practitioners
- Embed identity review into procurement intake Require IAM, security, and application ownership review before any SaaS contract moves forward. Capture federation requirements, admin roles, integration permissions, and offboarding expectations during evaluation rather than after deployment.
- Map every new SaaS app to an owner and lifecycle path Assign a clear business owner, technical owner, and access owner for each application. Document how joiner, mover, and leaver events will be handled for users, admins, and connected integrations.
- Add access governance to total cost of ownership Count access review effort, privileged admin review, logging, entitlement cleanup, and orphaned account removal as recurring costs. Use that total when comparing tools, not just license fees and implementation costs.
- Block SaaS rollouts without offboarding criteria Require a removal process for users, admins, and API connections before purchase approval. If the application cannot support reliable deprovisioning, treat that as a governance risk, not a minor operational inconvenience.
Key takeaways
- Software evaluation becomes an identity control problem once each new SaaS app adds users, admins, integrations, and offboarding obligations.
- The hidden cost of SaaS is often governance overhead, not licence price, because access reviews and deprovisioning continue long after purchase.
- IAM teams should be involved before contract approval so the organisation does not buy applications it cannot cleanly govern or retire.
Standards & Framework Alignment

| NIST CSF 2.0 | PR.AC-4 | Access permissions should be defined and controlled before apps are approved for use. |
| NIST Zero Trust (SP 800-207) | PR.AC-1 | SaaS selection affects trust boundaries and authenticated access paths across the estate. |
Inventory every non-human identity created by SaaS adoption and assign a lifecycle owner before go-live.
Key terms
- SaaS Governance: The set of controls used to manage who can adopt, access, and retire software-as-a-service applications. It combines procurement discipline with identity, security, and lifecycle oversight so that new tools do not create unmanaged access paths or orphaned accounts.
- Identity Sprawl: The growth of identities, permissions, integrations, and trust relationships that occurs as more applications are added. In SaaS environments, identity sprawl increases review effort, complicates offboarding, and makes it harder to understand who or what still has access.
- Lifecycle Ownership: The assignment of a clear accountable owner for provisioning, access review, change management, and deprovisioning. Without lifecycle ownership, SaaS applications often remain active after business need changes, leaving administrators, integrations, and accounts exposed longer than intended.
