Large Scale SIEM Implementation
Brief :
A major German IT banking provider required harmonizing its heterogeneous cybersecurity monitoring environment towards a centralized SIEM solution. In particular, the request focused on connecting more than 40.000 assets to the newly established central SIEM solution and developing more than 380 platform-specific use cases.
BxC was asked to lead the implementation of this centralized SIEM solution in order to provide holistic coverage with essential SIEM use case controls.
