Rethinking SIEM Economics with Microsoft Sentinel Data Lake
Overview
Security teams are generating more telemetry than ever, but traditional SIEM cost models often force a tradeoff between visibility, retention, and budget, pushing many organizations to limit how much data they keep, and with it, their ability to investigate incidents, hunt threats, and meet compliance requirements.
This session covered how Microsoft Sentinel Data Lake changes that equation by enabling low-cost, long-term storage of security data with on-demand analytics. We walked through how Sentinel Data Lake works alongside Microsoft Sentinel and why it's becoming a critical capability for modern SOCs looking to retain more data, reduce costs, and prepare their environments for AI-driven security tools.
What you'll walk away knowing.
Sentinel Data Lake improves SIEM cost efficiency
Low-cost, long-term storage separates retention from per-GB analytics spend, so keeping more data doesn't mean paying more to analyze it.
Long-term retention pays off beyond compliance
Holding more security data for longer strengthens investigations and threat hunting, not just audit readiness.
It's built for real SOC use cases
Investigations, threat hunting, and compliance all benefit from on-demand access to historical data that used to get aged out.
Enabling it takes deliberate configuration choices
Getting the most out of Sentinel Data Lake means thinking through what to route where, and how to optimize as usage grows.
