Large Scale SIEM Implementation

Technical implementation coordination and project management for a Security Information and Event Management (SIEM) platform based on IBM QRadar.

Case

Brief

A leading German IT banking service provider faced the challenge of consolidating their complex cybersecurity monitoring landscape into a unified Security Information and Event Management (SIEM) solution. The project encompassed the integration of over 40,000 assets into the new centralized SIEM platform and the development of more than 380 customized monitoring use cases specific to their banking environment.

BxC led the implementation of this comprehensive SIEM solution, ensuring complete visibility across the organization's IT infrastructure. The team established sophisticated detection and response capabilities while adhering to strict banking industry security standards. Through careful orchestration of the implementation process, the solution now provides holistic security monitoring and robust threat detection across all critical banking systems.
