Case Study: Disque Denúncia (Rio de Janeiro crime-tips service) achieves case analysis in hours instead of 15 days with Tableau Software

“Time is essential” Disque Denúncia and Tableau

Disque Denúncia is a Rio de Janeiro public safety project that collects anonymous reports of criminal activity; its database exceeds 2 million denunciations, each with multiple identifying details. The organization struggled to systematize and analyze this high volume of time-sensitive data—processes that were previously manual and could take up to 15 days—hindering rapid police response.

By deploying Tableau with implementation and training support from partner Path, Disque Denúncia now extracts and diagnoses trends in a few hours instead of weeks. Interactive dashboards help identify criminal migration patterns to support Police Pacifying Units, improve data quality and staff efficiency, and accelerate public-safety decision making.
