Phishing Triage Agent in Microsoft Defender

Microsoft has announced the public preview of its Phishing Triage Agent in Microsoft Defender. This new agent is designed to help security teams handle the massive volume of user-reported phishing emails with greater speed and accuracy.
The Phishing Triage Agent uses advanced AI reasoning to quickly analyze and categorize reported emails, identifying real threats and dismissing false positives, often processing thousands of messages in under 15 minutes. Unlike traditional rule-based systems, this agent adapts to complex scenarios and continuously learns from security analysts’ feedback to improve over time.
Integrated deeply with Microsoft Defender’s automation tools, the agent filters out roughly 90% of noise, freeing up analysts to focus on real, high-priority threats. A dedicated dashboard allows teams to track agent performance, feedback quality, and triage coverage in real time.
