    Microsoft Sentinel Data Lake

    A security data lake that stores and analyses security data cost-effectively at scale.

    Microsoft Sentinel data lake provides cost-effective, long-term storage and analytics for the massive volumes of security data modern SOCs generate — decoupling storage from analytics so you can retain everything affordably and query it for hunting, compliance, and AI. It is the data foundation of the unified Microsoft Sentinel platform. Faltrox operates it as the data layer of a managed SOC.

    Overview

    What Microsoft Sentinel Data Lake is

    SOCs face a dilemma: security data volumes are exploding, but ingesting and retaining everything in a traditional SIEM is prohibitively expensive — so teams drop data and lose visibility. The Microsoft Sentinel data lake solves this by decoupling storage from analytics: it stores large volumes of security data cost-effectively for the long term, and lets you query it when needed.

    It provides a scalable, affordable security data lake that retains high-volume and long-tail security data — the logs teams would otherwise drop — and makes it available for threat hunting, historical investigation, compliance, and AI-driven analytics. As the data foundation of the unified Microsoft Sentinel platform, it feeds detection, hunting, and Security Copilot. Faltrox operates it as the data layer of the managed SOC it runs, balancing cost, retention, and visibility.

    FAQ

    Common questions

    01Why does a SOC need a data lake?

    Because ingesting and retaining all security data in a traditional SIEM is prohibitively expensive, so teams drop data and lose visibility. The Sentinel data lake decouples storage from analytics, letting you retain everything affordably — including the long-tail logs you would otherwise drop — and query it when needed.

    02What can we do with the retained data?

    Threat hunting, historical investigation, compliance and audit retention, and feeding AI-driven analytics and Security Copilot — so the data that was too expensive to keep becomes available for detection, investigation, and AI.

    03How does it relate to Sentinel SIEM?

    The data lake is the cost-effective storage-and-analytics foundation of the unified Sentinel platform; the SIEM provides real-time detection and response. Together they let you keep more data affordably while still running fast detection on what matters. Faltrox balances the two.

    04Does it help with compliance?

    Yes — long-term, cost-effective retention supports compliance and audit requirements that mandate keeping security data for extended periods, which full SIEM retention often makes uneconomical.

    05How does Faltrox operate it?

    We operate the data lake as the data layer of the managed SOC we run — balancing cost, retention, and visibility, and making retained data available for hunting, investigation, compliance, and AI.
