DORA Requires Financial Entities to Prove ICT Data Lineage

DORA requires EU financial entities to maintain a continuously accurate, auditable Register of Information linking every ICT third-party provider to the critical or important functions it supports and documenting the associated data flows. With regulators increasingly comparing submitted registers against production environments after DORA took effect in January 2025, reliance on contract inventories, periodic architecture diagrams, and data catalogs can create compliance gaps because these tools often fail to capture current code changes, transformation logic, and embedded API dependencies. The text argues that deterministic, code-derived data lineage offers a more defensible approach by tracing data movement and ICT dependencies directly from application code and metadata, allowing the map to update as systems change. It presents Foundational as a platform for creating such live, audit-ready dependency maps and cites Vio’s reported reductions in potential data issues and development-cycle time as evidence of operational benefits beyond compliance.
