Microsoft Sentinel Data Lake: Revolutionising Security Analytics with Cost-Effective Long-Term Storage

Microsoft has unveiled an exciting development in cloud security: the Microsoft Sentinel Data Lake, currently in preview. This innovative solution promises to transform how organisations handle high-volume security data whilst significantly reducing operational costs. By decoupling storage from compute, Sentinel Data Lake offers unprecedented flexibility and economic efficiency for security operations.

The Economic Advantage

The preview pricing structure demonstrates Microsoft's commitment to affordability, with data lake ingestion priced at $0.05 per GB, storage at just $0.026 per GB per month, and query operations at an incredibly low $0.005 per GB of data analysed. Perhaps most compelling for organisations evaluating the solution, the preview includes 30 days of free storage and complimentary data processing during the preview period. This pricing model represents a substantial departure from traditional security information and event management (SIEM) solutions, where storage costs often escalate dramatically with data retention requirements.
