Microsoft SentinelMicrosoft Sentinel SIEM
A cloud-native SIEM that scales elastically across your whole estate.
Microsoft Sentinel is a cloud-native SIEM that collects security data at cloud scale across users, devices, apps, and infrastructure — on-premises and in multiple clouds — then detects, investigates, and responds to threats with AI and automation. It removes the infrastructure burden of legacy SIEM and unifies security operations. Faltrox operates it as the core of a managed SOC.
Overview
What Microsoft Sentinel SIEM is
Legacy SIEMs are expensive to scale, slow to deploy, and buried in infrastructure management — just as security data volumes explode. Microsoft Sentinel is a cloud-native SIEM built for that reality: it scales elastically with no infrastructure to manage, ingests data from across the estate, and applies AI and automation to cut through the noise.
It collects data at cloud scale from Microsoft and hundreds of third-party sources via built-in connectors, detects threats with analytics and machine learning, investigates incidents with rich context and AI, and responds through automation and orchestration. Now part of Microsoft’s unified security operations platform alongside Defender XDR, it gives one place to run the SOC. Faltrox operates Sentinel as the core of the managed SOC it runs — onboarding data, tuning detections, and driving investigation and response.

FAQ
Common questions
01How is Sentinel different from a legacy SIEM?
It is cloud-native — it scales elastically with no infrastructure to deploy or manage, ingests data at cloud scale via built-in connectors, and applies AI and automation. Legacy SIEMs are expensive to scale and buried in infrastructure work; Sentinel removes that burden while adding modern detection and response.
02Does it only work with Microsoft data?
No — it ingests data from Microsoft and hundreds of third-party sources via built-in connectors, so it can be the SIEM over a mixed-vendor estate across on-premises and multiple clouds, not just a Microsoft one.
03How does it relate to Defender XDR?
Sentinel is now part of Microsoft’s unified security operations platform alongside Defender XDR, so SIEM and XDR run in one place — Sentinel provides broad data collection and correlation, Defender XDR provides deep first-party detection. Faltrox runs them as one SOC.
04Can it automate response?
Yes — through Security Orchestration, Automation, and Response (SOAR) playbooks, it automates and orchestrates response across your tools, so common response steps run automatically rather than by hand. Faltrox builds those playbooks.
05How does Faltrox operate it?
We run Sentinel as the core of the managed SOC we deliver — onboarding your data, tuning analytics and detections, building automation playbooks, and driving investigation and response, so you get a modern SOC without operating the platform yourself.
