About this integration

The following instructions will guide you through the process of configuring the RST Threat Feed in Microsoft Sentinel using the STIX v2.1 data format and the TAXII protocol. This integration allows you to populate the standard threat intelligence table in Microsoft Sentinel automatically. Please note that this integration needs to be configured per feed for each Sentinel instance. This integration will only pull attributed indicators.
