Microsoft Defender Threat Intelligence is a complete threat intelligence platform that enables security professionals to ingest, analyze and act upon massive signal collected from across the internet, processed by security experts and machine learning. It allows users to uncover and understand their organization's external attack surface, including context around vulnerabilities and the tools and systems adversaries use to attack and exploit them.
Microsoft Defender Threat Intelligence Community Edition is a free, lightweight version of Defender TI, offering the same industry-leading threat-hunting experience with limited access to Defender TI data sets. Users can expedite investigations by connecting internal activity, events, and incident indicators of compromise (IOCs) artifacts to external threats, attackers, and threat tooling.
