R39 — SaaS Security Posture / Tenant Misconfiguration
Productivity, CRM, HR, source-control and similar SaaS tenants drift into over-permissive sharing, third-party OAuth grants, and disabled logging. Distinct from R15 (IaaS/cloud-infra) because the surface is tenant settings, not VPCs/IAM-roles. SSPM is the dominant control; identity governance limits OAuth blast radius. Residual exists because every new SaaS adds attack surface no central team owns.

Real-world parallel
SaaS security posture / tenant misconfiguration is the cloud-misconfiguration risk for SaaS rather than IaaS. Sharing settings in M365 / Google Workspace / Salesforce, OAuth-app sprawl, and over-permissive admin assignments compound silently. SSPM tooling (AppOmni, Adaptive Shield, Wing) automates the assessment.
