The Y-Engine is Zscaler's proprietary AI and machine learning engine that powers the Zscaler Digital Experience (ZDX) service. It processes vast amounts of telemetry data collected from user devices to automatically identify performance issues, pinpoint their location (user device, network, or application), and provide automated root cause analysis. This engine is fundamental to ZDX's ability to move beyond simple monitoring to actionable intelligence, enabling IT teams to resolve user experience problems efficiently.

A. OAuth request: This is an authorization framework for delegated access, completely unrelated to data analysis or root cause determination.

B. Application Performance: This is a category of metrics that ZDX monitors and the Y-Engine analyzes, not the analysis engine itself.

D. Copilot: Zscaler Copilot is a generative AI assistant for security operations, not the specific engine responsible for automated root cause analysis within ZDX.
