We’re introducing Data Security Triage Agent summaries and categorizations for Data Loss Prevention (DLP) alerts directly within the Microsoft Defender XDR portal. This update helps security analysts triage DLP alerts more efficiently by surfacing AI-generated summaries and categorizations created by the Microsoft Purview Data Security Triage Agent.
