The use of graph technology, specifically Neo4j, is crucial for managing complex identity and access management in financial services firms. The centralized entitlements structure can lead to "permissions creep" and increased risk of data breaches, but graph technology provides a solution by tracking and adapting to interconnected relationships. This enables administrators to easily determine who has what permissions, reducing the risk of data breaches and providing real-time insights into entitlement access. A Global 500 financial services company uses Neo4j to manage user identity and access management for its investment banking platform, demonstrating the flexibility and scalability of graph technology in this context. By using Neo4j, IT organizations can create an effective competitive advantage by mapping out authorizations at individual and group levels and tracking them dynamically as users' roles change within the company.
