Microsoft Sentinel Deployment Steps

Microsoft Sentinel, Microsoft’s intelligent security analytics service, offers enterprises scalable, cloud-native solutions for:

• Security Information and Events Management (SIEM)
• Security Orchestration, Automation, and Response (SOAR)

With Sentinel, organizations have a unified platform for attack detection, threat visibility, proactive hunting, and threat response.

Key Features of Microsoft Sentinel:

• A holistic security view reduces stress from complex attacks and streamlines responses.
• Data collection at cloud scale across all assets.
• Advanced threat detection using Microsoft’s vast threat intelligence and analytics.
• Intelligent threat investigation tools driven by AI.
• Quick incident response with built-in orchestration and automation.

Microsoft Sentinel natively integrates with other Azure services, such as Log Analytics and Logic Apps. It augments your investigations with AI, offers Microsoft’s threat intelligence feed, and even lets you incorporate your intelligence.
