The Shadow Supply Chain: The SSO & AI Visibility Gap | UpGuard

This analysis examines the growing "shadow supply chain" problem where a large portion of vendor usage bypasses SSO and procurement, highlighting measured gaps (e.g., 31.4% of vendor interactions bypass SSO, a 72.9% inventory gap, and high rates of unmonitored Shadow AI usage including 64% of ChatGPT Enterprise instances), the resulting illusion of control from relying on identity providers and vendor security scores, and the increased risk from unmonitored AI assistants and fragmented tools that may exfiltrate sensitive data—calling for usage-based discovery and browser-level visibility to remediate the gap.
