The challenge

Block manages exabyte-scale data under strict compliance regimes (GDPR, CCPA, PCI DSS, SOX, GLBA, PSD2) while supporting thousands of data users across decentralized systems, with a relatively small team responsible for the work.

The solution

Block implemented Select Star for automated column-level lineage and centralized metadata management, using API-driven integrations with its existing platforms after an eight-month evaluation.
