SaaS integrations and app sprawl: where IAM teams lose control

TL;DR: SaaS integrations can automate onboarding, offboarding, billing, and app-to-app data exchange, but they also expand the identity surface across APIs, permissions, and shadow IT, according to Zluri. The governance challenge is not integration itself, but whether organisations can track and revoke the access created by each connection.

By the numbers:

• Only 5.7% of organisations have full visibility into their service accounts.

Questions worth separating out

Q: How should security teams govern SaaS integrations as part of IAM?

A: Treat each integration as an identity-bearing connection with an owner, scope, credential, and revocation path.

Q: Why do SaaS integrations create governance risk for organisations?

A: They create durable permissions that often outlive the business need that justified them.

Q: What do teams get wrong when they review connected SaaS apps?

A: They often review the application list but not the credentials and scopes behind each connection.

Practitioner guidance

• Inventory every SaaS integration as an identity object Record the owner, scopes, authentication method, data touched, and revocation path for each connection.
• Tie provisioning and offboarding to the integration lifecycle When an app, department, or business process changes, confirm that connected permissions, service accounts, and tokens are reviewed at the same time.
• Review unused or low-value integrations for removal Prioritise dormant connections, duplicate connectors, and app links with unclear business ownership.
