A Living Data Catalog Reduces Risk While Cutting Discovery Costs

The challenge for modern organizations is no longer simply collecting information but understanding where it lives, how it is used, and what obligations attach to it. According to an Exterro blog post, a living data catalog is the response to this challenge.

A data catalog doesn’t store the actual data. It remains in its original location and stores intelligence about that data. Too often misunderstood as a static inventory or technical reference, a living data catalog functions as an authoritative data source for the organization. It captures not only where data resides, but what it contains, how old it is, who it relates to, and which legal, privacy, and security requirements apply. By enriching technical metadata with business and legal context, the data catalog becomes a shared operational asset.

A data catalog also transforms the discovery process. Without clear insight, organizations tend to over-preserve and over-collect, driving up costs and risk. A data catalog enables precise identification of relevant systems and custodians, supports defensible preservation through documented audit trails, and exposes shadow systems that might otherwise expose the data to risk. 

The benefits extend well beyond litigation. The same intelligence that streamlines discovery also accelerates incident response and regulatory compliance. When a breach occurs, knowing exactly which systems hold sensitive data allows legal teams to assess impact quickly and meet tight notification deadlines. For privacy operations, centralized visibility simplifies responding to data subject requests. This visibility is vital for compliance with complex regulatory regimes and reducing the likelihood of costly missteps.

Establishing a living data catalog equips legal leadership to quantify risk, justify governance investments, and build trust with regulators and customers. In a global environment where data proliferation is inevitable, a single scalable interface becomes a strategic advantage, ensuring meaningful data reduction and cost control.
