Troubleshoot Device Issues Faster with ZDX

Introduction: The Hidden Cost of "Everything's Fine"

In large enterprises, many users suffer in silence, enduring slow applications, frequent crashes, and persistent device instability without ever opening an IT ticket. This "silent pain" drains productivity, damages employee confidence, and creates a massive blind spot for IT. Traditional tools, reliant on ticket data, only see the users who complain—missing the vast majority of underlying issues.

This hidden instability creates distinct, critical challenges for specialized IT teams:

• For the Service Desk: Escalating hidden issues and high resolution times due to a lack of complete data.
• For Network Operations (NetOps): Difficulty correlating device-level instability (like driver conflicts) with network and application performance issues.
• For Network Security (NetSec): Gaps in visibility and inconsistent context that complicate Zero Trust adoption and experience model.

Zscaler Digital Experience (ZDX) Device Health directly addresses this by detecting system and software crashes, delivering a clear device health score, and enabling remote remediation before users are forced to file a ticket.

The Silent Challenges for Key Personas

When device problems go unreported, key IT teams are left to deal with the consequences blindly:

1. Service Desk Teams

• Challenge: They only see the loudest problems. The majority of slow-downs and minor crashes remain hidden, leading to an inaccurate view of service quality. The Service Desk workload is reactive, chasing incidents based on incomplete or late user reports.
• Result: Long triage and resolution times because they lack the cross-domain visibility to pinpoint the root cause (Is it the device, the network, or the app?). This leads to higher operational overhead and lower employee satisfaction.

2. Network Operations (NetOps) Teams

• Challenge: NetOps needs to ensure application and network experience is stable, but a fault on the device can masquerade as a network issue. They struggle to see how device issues relate to app and network experience because traditional monitoring tools are siloed.
• Result: Wasted time troubleshooting network performance only to find the root cause was a faulty Wi-Fi driver, device CPU issues, or a browser hang on the device, not the network path itself. Without end-to-end visibility, the NetOps team wastes critical time debugging network issues that are actually rooted in the endpoint device.

3. Network Security (NetSec) Teams

• Challenge: In a Zero Trust environment, security and experience must be unified. NetSec teams require consistent context across the entire data path. Multiple monitoring agents create complexity and potential security gaps.

Result: Increased cost and complexity from having to integrate and correlate data from multiple, non-unified endpoint, network, and application tools, which undermines a single-platform, Zero Trust strategy.

The ZDX Device Health Solution

ZDX Device Health provides the visibility and control needed to eliminate silent pain and empower IT teams.

ZDX for the Service Desk: Proactive Resolution and Efficiency

By providing real signals from devices (memory usage, disk usage, Wi-Fi signal quality, battery, CPU usage, software crashes, average disk queue length, system crashes) and turning them into clear health scores, the Service Desk can act without waiting for tickets. Beyond a complete device score which may imply one or more key metrics are performing badly, ZDX captures trends and groups scores for individual, key metrics like CPU performance and memory performance, allowing IT to precisely target underperforming devices.

• Proactive Fixes: ZDX detects patterns (e.g., a specific driver causing blue screens on 2% of devices) and allows IT to trigger fixes via existing management tools (Intune, Jamf).
• Shorter Resolution Time: Cross-domain visibility allows IT to confirm improvement and close the loop: Detect signal → Identify cause → Apply fix → Confirm improvement.
• Smarter Asset Management: Data shows which devices truly need replacement versus those that only need a software or driver fix, reducing unnecessary asset costs.

ZDX for NetOps: Cross-Domain Visibility and Precision

ZDX removes the monitoring silos that complicate root cause analysis. Because all traffic passes through the Zscaler Zero Trust Exchange, it captures device, network, and application performance in one stream.

• Correlated Experience View: NetOps can see how device stability impacts network and app performance in a single view, allowing them to pinpoint whether a slow video call is due to the device, the path performance, or app availability. For example, if NetOps suspects a network slowdown, ZDX's end-to-end insight immediately confirms if the problem is device-based (e.g., high CPU usage). This clarity allows them to easily redirect the issue to the Service Desk, preventing wasted time on network traces.
• Precise Troubleshooting: They can quickly identify which models, OS versions, or drivers are causing the most failures, enabling targeted action to prevent the problem from spreading. By providing a clear device health trend and detailed health data on the device/user page, ZDX clearly shows the problem, drastically reducing the Mean Time to Resolution (MTTR).

ZDX for NetSec: Unified Zero Trust Experience

ZDX is built on the same architecture as Zscaler Internet Access and Zscaler Private Access, enabling a unified approach to security and experience.

• Single Data Path & Consistent Context: All device metrics align with application and path data, allowing clear cause analysis and maintaining consistency within the Zero Trust model.
• Unified Operations: Security and experience share a single platform, eliminating the need for multiple agents and tools. This reduces cost and management effort while improving insight across the entire digital environment.
