SaaS subscription sprawl: what it means for IAM and access control

TL;DR: Decentralised SaaS purchasing creates duplicate subscriptions, unused licences, and weaker access governance because departments add tools faster than IT can inventory or review them, according to Zluri. The real issue is not cost alone: unmanaged SaaS expands the identity surface, complicates offboarding, and leaves security teams blind to who still has access.

Questions worth separating out

Q: How should security teams govern SaaS sprawl across departments?

A: Security teams should treat SaaS sprawl as an identity and lifecycle issue, not only a procurement issue.

Q: Why does SaaS subscription management matter to IAM teams?

A: Because every subscription introduces accounts, admins, roles, and permissions that can outlive the business need for the tool.

Q: What breaks when SaaS subscriptions are managed only by finance or procurement?

A: Access governance breaks because licence ownership is not the same as entitlement ownership.

Practitioner guidance

• Build one SaaS inventory tied to ownership Map every subscription to a business owner, technical owner, renewal date, and entitlement source so the estate can be governed as a control surface, not a spreadsheet.
• Link renewal reviews to access certification Require every renewal decision to confirm whether the application still has valid users, valid approvers, and a current offboarding path for leavers and dormant accounts.
• Integrate SaaS governance with IAM and IGA Feed application discovery into identity workflows so access requests, role changes, and removals are visible alongside licence usage and contract status.
