Case Study: a leading retailer achieves 85% SIEM cost savings with CyberProof and Microsoft Sentinel

Threat-led SIEM transformation delivers 85% cost savings for international retailer

An international retailer faced significant challenges in reducing costs and improving effectiveness across its five fragmented SIEM platforms. Struggling with visibility gaps, inefficient data management, and a costly legacy Splunk environment, the company sought a reliable strategy to migrate to a cloud-native SIEM. Their key objectives were to achieve substantial cost savings, build an optimized architecture, and gain self-sufficiency. They engaged CyberProof for its expertise with the Microsoft Security Suite to help with this transformation.

CyberProof implemented a consultative program to migrate the retailer from Splunk to Microsoft Sentinel. The solution included a threat-led design, manual translation of detection rules, and an intelligent telemetry layer using Cribl to prioritize high-value data and archive the rest to a data lake. This resulted in an 85% cost reduction in data storage and a more efficient security operation. CyberProof's hands-on approach also provided extensive training, empowering the client's internal team to become proficient in managing the new platform and ensuring long-term resilience.
