The Visibility Illusion: Why Your Supplier Data Doesn't Tell the Whole Story

An analysis of how supplier data confidence, coverage and verification collapse the further you look beyond Tier 1, and what that means for hidden risk, regulatory exposure and resilience across global supply chains.

What’s inside the report

  • Why Tier 1 confidence is misleading: how firms build strong verification at Tier 1, why that data may still be less reliable than it looks, and what changes the moment you move one tier upstream.
  • The evidence gap regulators will test: which supplier sustainability obligations firms can back with auditable evidence today, and which ones fall apart under scrutiny.
  • Real risk, limited response: the cost, capability and data barriers stopping firms extending verification deeper, and how leading teams are prioritising supplier engagement where it counts most.

Key Findings

82% of firms have solid supplier data at Tier 1 — just 12% say the same for Tier 2 

Confidence in supplier data falls from 90% at Tier 1 to just 2% by Tier 3

Over 90% of firms believe deeper verification would reveal risks they can’t currently see
