Retail Company Reduces Data Costs by 85% with SIEM Transformation
Download the PDFAbout the client
The client is a leading retailer with over 1,000 stores across the United States and Canada. They offer a wide range of products and services to both consumers and businesses. To streamline their security infrastructure, the company decided to consolidate under a single, trusted cloud vendor. As an existing Microsoft 365 user, they embraced Microsoft’s comprehensive security suite, aligning their security approach with the industry’s best cloud security solutions.
The client's challenge
The client faced significant challenges in reducing operational costs and improving the efficiency of their security operations. Having tried five different SIEM solutions over the last decade, they needed a reliable strategy to migrate from their on-premises Splunk SIEM to a cloud-native solution, Microsoft Sentinel. The key objectives for this transformation were:
- Cost Savings: Reduce infrastructure, data ingestion, retention, and operational maintenance costs.
- Optimized Design: Build an intelligent SIEM system to efficiently manage and streamline security data ingestion and logging.
- Self-Sufficiency: The client needed a partner who could provide the expertise and training to empower their internal team to maintain and optimize the system independently.
The benefits of CyberProof
- 85% Reduction in Data Costs: By adopting a cloud-native, optimized design, the company reduced costs related to data ingestion, retention, and licensing fees, along with cutting infrastructure and maintenance overhead.
- Increased Autonomy: Through expert coaching and hands-on training, the client gained full control over their SIEM system, enabling them to manage and optimize their environment independently.
- Streamlined Data Management: CyberProof implemented an intelligent layer in the design, using Cribl and Sentinel to ensure only relevant security data was ingested into the SIEM, while archiving non-relevant data for compliance purposes.
- Enhanced Control & Visibility: The business now enjoys complete visibility into their security operations, consolidating their security stack and ensuring peace of mind through a future-proof system.
Our solution
CyberProof worked closely with the client to develop and implement a successful migration strategy. Our solution included a series of hands-on workshops and ongoing consultancy to ensure the transformation was seamless. Key components of the solution were:
- Cloud-Native Architecture: We implemented a cost-efficient, cloud-first design using Microsoft Sentinel, optimized for data management and security.
- Smart Data Ingestion & Management: We created an intelligent layer with Cribl and Sentinel to ensure only relevant data was ingested into the SIEM, improving both cost-efficiency and data management.
- Expert Training & Knowledge Transfer: Through in-depth training sessions, we ensured that the client’s internal team could independently manage and optimize their SIEM system post-migration.
This collaboration ensured the business not only migrated successfully but also had the tools to manage their system efficiently, reducing reliance on external vendors.
