AI XDR（AI-powered Extended Detection & Response）是一类以“跨域遥测数据汇聚、智能关联和响应闭环”为核心的检测与响应平台，为安全运营场景提供事件级的统一视图与自动化处置能力。AI XDR通过原生传感器、安全组件、开放接口（API、日志、第三方等），持续汇聚来自端点、身份、邮件、网络、云工作负载等多层面的跨域安全遥测数据；继而运用AI/ML技术，对这些海量、异构的原始数据自动进行规范化、上下文化处理。在此基础上，实现对原本孤立、泛滥的分散告警的智能关联，并通过智能研判压缩成具有完整攻击链视角的“可处置事件”，形成风险评分与处置优先级、处置决策。
综合而言，AI XDR通过全域真实联动、全量联动、语义联动的智能化检测与响应能力，实现从调查、处置到复盘的安全运营闭环，其根本价值在于以更少的人力成本、产品采购成本获得更快的发现、更准的研判和更短的响应时间。
AI-powered Extended Detection and Response (AI XDR) represents a new generation of security platforms built on three core principles: cross-domain telemetry aggregation, intelligent correlation, and closed-loop response. These platforms provide security operations with a unified, event-centric view and automated remediation capabilities.
Leveraging native sensors, integrated security components, and open interfaces (such as APIs, logs, and third-party connectors), AI XDR continuously ingests and harmonizes cross-domain telemetry from endpoints, identities, email, networks, and cloud workloads. This vast and diverse data is automatically normalized and enriched through artificial intelligence and machine learning, enabling advanced correlation across previously siloed and overwhelming alerts. Through analytical reasoning, AI XDR distills these alerts into actionable events that map the full attack chain—complete with risk scoring, prioritization, and recommended response actions. By unifying and contextualizing detection and response in a holistic and semantically aware framework, AI XDR closes the security operations loop from investigation and remediation to post-incident analysis.
Ultimately, AI XDR delivers faster threat discovery, more accurate validation, and shorter response cycles, while reducing manual effort and the overall cost of security ownership.
