Verizon’s 2026 report found third-party involvement in 48% of breaches, up 60% on last year’s dataset. Only 23% of third-party organizations fully fixed missing or improperly secured multifactor authentication on cloud accounts. Only 26% of critical vulnerabilities were fully fixed in 2025, down from 38%.
Duties arrive from several places: laws, contracts, customers and standards. Each uses its own words and asks for its own evidence. Teams often answer each one separately, so the same control is tested three times and nobody can say which duties it covers. Standards also move. PCI DSS v4.0 was retired on 31 December 2024, and its future-dated requirements took effect on 31 March 2025.
What an assessor, a regulator or a customer wants to see is evidence that a control works, and works at the suppliers you rely on.
