The Trend Micro Deep Discovery Inspector (DDI) Splunk Add-On addresses the lack of effective tools for parsing and categorizing Trend Micro DDI logs in Splunk. This add-on ensures accurate log extraction, alignment with Splunk's Common Information Model (CIM), and enhances threat detection and incident response capabilities. Developed based on official Trend Micro DDI documentation, the add-on fills a critical gap in the Splunk ecosystem and will be continuously updated, with plans to add dashboards for improved security monitoring.
