TL;DR: Hidden, duplicated, legacy and unmanaged data stores expand breach blast radius, and Ground Labs argues that data intelligence is what makes exposure reduction practical across modern estates, according to Ground Labs. The governance issue is not discovery for its own sake, but removing data copies and forgotten repositories that add risk without adding value.
NHIMG editorial — based on content published by Ground Labs: How data intelligence reduces data breach blast radius
By the numbers:
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, with 46% confirmed and 26% suspected.
- When AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes and as quickly as 9 minutes in some cases.
Questions worth separating out
A: Start by locating where sensitive data actually lives, including duplicates, exports, archives, and inherited repositories.
A: Poor governance makes it harder to know what data exists, who can reach it, and which controls actually protect it.
Q: What are the signs that data retention is creating unnecessary security risk?
A: Look for stale exports, duplicated records, archives no one can justify, and repositories that have no clear owner or business purpose.
Practitioner guidance
- Build an estate-wide sensitive data map Identify where regulated, confidential, and business-critical data exists across cloud, SaaS, legacy, and inherited systems, then keep the map current as systems change.
- Delete redundant data copies on a schedule Use retention rules to remove duplicated records, stale exports, and legacy archives that no longer support a business purpose or regulatory need.
- Tie data ownership to system ownership Assign accountable owners for repositories that contain sensitive information, including inherited stores created during migrations or acquisitions.

Data intelligence is becoming a breach containment control, not just a discovery function. Organisations often treat data discovery as a hygiene exercise, but the article shows that its real value is limiting the amount of information a breach can reach. When duplicated and legacy stores remain outside normal management, they become exposure multipliers. For identity and governance teams, that means blast radius reduction must be measured alongside access control. The practitioner conclusion is straightforward: inventory is only useful when it drives removal, restriction, or monitoring decisions.
A question worth separating out:
Q: When should organisations prioritise data deletion over broader data discovery projects?
A: Prioritise deletion when discovery already shows repeated copies, legacy stores, or data that no longer has a business purpose. At that point, the risk comes less from not knowing enough and more from leaving unnecessary data in place. Removing that data reduces exposure faster than expanding discovery alone.
