SaaS app sprawl in spreadsheets: what IAM teams miss

TL;DR: Manual SaaS tracking works only for very small environments, but spreadsheet-based records quickly become inaccurate as app counts, ownership, renewals, and license details grow, according to Zluri. The governance gap is that spreadsheets cannot surface unapproved apps or automate discovery, so visibility and control fall behind business growth.

By the numbers:

• Zluri says its app discovery engine surfaces a SaaS landscape with near 100% accuracy in less than 5 minutes.
• Zluri says customers have seen 30% - 40% cost savings on SaaS by eliminating duplicate, unused, and abandoned apps.

Questions worth separating out

Q: How should security teams manage SaaS app inventory as the business grows?

A: They should replace manual spreadsheets with an authoritative inventory built from SSO, spend, and endpoint signals.

Q: Why do spreadsheets fail as a SaaS governance control?

A: Because they are static, manual, and easy to drift from reality.

Q: What breaks when SaaS ownership is not assigned clearly?

A: Renewal decisions, access reviews, and cleanup tasks all lose accountability.

Practitioner guidance

• Establish a single authoritative SaaS inventory Combine SSO, expense, browser, and desktop signals so app records do not depend on manual spreadsheet updates.
• Tie every SaaS app to an accountable owner Require one named business owner and one technical steward for each application.
• Reconcile renewals against actual usage Check whether the app is actively used before any renewal discussion.
