Financial institutions still struggle with costly manual efforts to patch gaps in their systems, resulting in higher operational expenditure (OPEX). Neo4j's graph technology was designed to resolve these gaps and complement existing solutions, particularly in the payments and transaction monitoring spaces. By automating complex calculations and entity resolution, Neo4j reduces OPEX spent on manual payment message repairs, detects suspicious transactions more effectively, and frees up resources for financial institutions to achieve a synchronized positive effect across all three operational spaces. With its graph database, Neo4j has proven effectiveness in reducing OPEX by up to 0.7% and improving the accuracy of transaction monitoring.
