Understanding Data Exporting to Microsoft Sentinal

This article describes how to set up and use Microsoft Sentinel (formerly Azure Sentinel). It is a scalable, cloud-native, security information event management (SIEM) and security orchestration automated response (SOAR) solution that integrates with the Perimeter 81 platform. Azure Sentinel delivers intelligent security analytics and threat intelligence across the enterprise, providing a single solution for alert detection, threat visibility, proactive hunting, and threat response. You can configure your Perimeter 81 data stream to Microsoft Sentinel to have full visibility of your Perimeter 81 activity.
