Shadow IT in SaaS: where IAM teams lose control first

TL;DR: Shadow IT in SaaS grows when employees adopt unsanctioned apps, stored credentials, and unvetted vendor access outside IT oversight, creating security, compliance, and data-loss exposure, according to Zluri. The governance gap is no longer whether people will bypass approved tools, but whether identity teams can still see, scope, and revoke the access they never approved.

By the numbers:

• 80% of the employees admit that they use apps that aren’t approved by IT.
• 57% of IT leaders are concerned about shadow IT.

Questions worth separating out

Q: How should security teams govern shadow IT in SaaS environments?

A: Start by treating shadow apps as identity-bearing systems, not just unsupported software.

Q: Why do unsanctioned SaaS apps create more risk than software sprawl alone?

A: Because the risk is not only the tool.

Q: What do teams get wrong about SaaS access reviews?

A: They often review the application name but not the actual permission scope.

Practitioner guidance

• Build a shadow SaaS inventory from identity data Correlate SSO logs, browser telemetry, finance records, and OAuth consent data to identify apps that exist outside approved intake.
• Classify every unsanctioned app by access risk Separate low-risk personal productivity tools from apps that store customer data, internal files, or privileged credentials.
• Remove secret storage from unmanaged locations Eliminate browser-saved passwords, spreadsheets, and consumer vaults for work credentials.
