SaaS, IT Atlas

Overview

SaaS shifts operations to the vendor but concentrates risk in identity and configuration. Every SaaS tenant is a separate administrative surface with its own roles, sharing model, audit log and integration permissions.

Sustainable SaaS management means a register of applications with owner, data classification, SSO status, provisioning method, admin roles, log retention and exit plan.

Security considerations

Require SSO with MFA and SCIM provisioning; local accounts in SaaS bypass every corporate control.
Review OAuth integrations and third party app permissions per tenant.
Confirm audit log retention and backup/export capability before onboarding.
