AI agents enrich alerts with device context, user login history, and IP intelligence before triaging. AI agents filter out difficult-to-tune alerts with short natural language prompts. A 24/7 team of detection and response specialists validates threats and reduces noise. Managed Detection & Response (MDR) includes threat hunting across clouds, endpoints, and identities, with scoped findings that carry evidence and next steps.

For response, Managed Detection & Response (MDR) can automatically block URLs and IoCs via ZIA, isolate endpoints via EDR, and suspend users via the customer's IDP. Playbooks are no-code and customizable. Customers can choose team oversight to initiate specific response actions, or choose to automate. Managed Detection & Response (MDR) alerts can be sent to a SIEM, SOAR, or ITSM platform to align with existing workflows.
