Gartner describes Security Information and Event Management (SIEM) as technology that supports threat detection, compliance and security incident management through the collection and analysis (both near real time and historical) of security events, as well as a wide variety of other event and contextual data sources. The core capabilities are a broad scope of log event collection and management, the ability to analyse log events and other data across disparate sources, and operational capabilities (such as incident management, dashboards, and reporting).

Microsoft’s SIEM Solution
Launched in 2020, Microsoft’s SIEM solution is Microsoft Sentinel, a modern, cloud-native SIEM solution that collects security data from the entire organization. Using hundreds of connectors and AI to help SecOps teams prioritize the most important incidents, Microsoft Sentinel includes user and entity behavior analytics (UEBA) and rich security orchestration, automation, and response (SOAR) capabilities.
Microsoft’s SIEM solution, Microsoft Sentinel, was recognized as a Leader in the 2022 Gartner Magic Quadrant for Security Information and Event Management.
Microsoft Sentinel delivers intelligent security analytics and threat intelligence across the enterprise. With Microsoft Sentinel, you get a single solution for attack detection, threat visibility, proactive hunting, and threat response. Microsoft Sentinel uses advanced AI and machine learning to correlate alerts from diverse sources, identify anomalies and patterns, and prioritize the most critical incidents. You can also leverage Microsoft’s threat intelligence stream and bring your own threat intelligence to enrich your investigation and detection.
Microsoft Sentinel is a scalable, cloud-native solution that integrates with your existing security tools and data sources. You can easily connect your logs with Microsoft Sentinel using built-in data connectors for all your Microsoft security tools but also 100’s of third-party tool as well,
Microsoft Sentinel Overview
- Collect data at cloud scale from all your sources, both on-premises and in multiple clouds.
- Detect previously undetected threats and minimize false positives using Microsoft’s analytics and unparalleled threat intelligence.
- Investigate threats with artificial intelligence and hunt for suspicious activities at scale, tapping into years of cybersecurity work at Microsoft.
- Respond to incidents rapidly with built-in orchestration and automation of common tasks.
Microsoft Sentinel enables you to investigate threats with artificial intelligence and hunt for suspicious activities at scale. You can use interactive dashboards and workbooks to visualize and analyze your data, drill down into specific events and entities, and get insights into the root cause and impact of an attack. You can also use notebooks to run queries and scripts, apply machine learning models, and collaborate with other analysts. Microsoft Sentinel provides you with built-in hunting queries and notebooks based on years of cybersecurity work at Microsoft.
Microsoft Sentinel helps you respond to incidents rapidly with built-in orchestration and automation of common tasks. You can use playbooks to trigger actions based on specific conditions or events, such as sending notifications, creating tickets, blocking IPs, isolating devices, and more. You can also use logic apps to create custom workflows that integrate with other services and tools. Microsoft Sentinel allows you to automate repetitive tasks and streamline your response process.
