Which feature in ZDX provides visibility into SaaS and private applications?

The feature that provides visibility into SaaS and private applications is the Application performance metrics. This capability is essential for administrators as it allows them to assess and monitor how applications are performing from the user's perspective. Application performance metrics gather crucial data on various factors such as response times, availability, and user experience across different applications, both SaaS and private. This visibility ensures that organizations can identify performance issues and take corrective actions swiftly, ultimately leading to improved user satisfaction and productivity.

While automated root cause analysis through the Y-Engine is valuable for troubleshooting and understanding underlying issues related to performance, it does not, in itself, provide the broad visibility into application performance metrics as mentioned in the question. The other options, such as user device inventory and network latency analysis, serve specific purposes in terms of understanding users and network conditions but do not specifically focus on the performance metrics of applications themselves. Thus, application performance metrics stand out as the feature that directly addresses the need for insight into both SaaS and private applications.
