A tier-1 bank cut data-leak risk with classification-aware DLP

Rolling out Veriket classification and Verikor DLP across tens of thousands of endpoints — without drowning analysts in false positives.

The challenge

The bank moved customer-financial data across email, web and USB every day, and its legacy regex DLP produced so many false positives that analysts had begun ignoring alerts.

With BDDK, PCI DSS and KVKK obligations, leadership needed enforceable control and audit-ready evidence — not another shelved tool.

The Siberson solution

1

Classify at source

Veriket labelled customer-financial data across the estate, giving every control real context.

2

Enforce with context

Verikor applied label-aware policy across email, USB, web, cloud and print.

3

Cover the images

Endpoint offline OCR caught sensitive data hidden in scans and screenshots.

4

Prove control

Every allow, warn and block became evidence mapped to BDDK, PCI DSS and KVKK.
