Proactive monitoring has transformed digital experience and now optimizes application delivery
With ThousandEyes, there are some configuration and metric screens that are not entirely intuitive with ThousandEyes, so they can certainly improve in terms of the usability of certain metric screens. ThousandEyes can also offer deeper traffic insights relative to specific applications, so detailed analytics on application-level traffic would help in better understanding and managing our network resources effectively. I would say that ThousandEyes can also, in terms of providing more extensibility with other observability tools, offer more out-of-the-box integrations with other observability tools so that ThousandEyes can serve as that single source of truth, so that we don't necessarily need to go to other tools to be able to be that one-source dashboard. I think there's a lot that ThousandEyes can continue to improve on there. The issues that I've talked about, including extensibility with other platforms and the improvement of accessing specific metric screens in order to be able to provide for fuller access and more detailed access to network-level metrics would make the platform feel less complicated to navigate. It wouldn't require as many manual integration inputs.

Unified monitoring has improved SaaS troubleshooting and reduces MTTR for remote users
In my opinion, the best features Zscaler Digital Experience (ZDX) offers are Zscaler Digital Experience (ZDX) Insights and scoreboards for quick health visibility. I can analyze the path to identify what the bottleneck of the application is, and I can also diagnose the endpoint for device-level root cause analysis, which is very helpful. Scoreboards and root cause analysis have helped my team significantly, as a scoreboard represents a 100% healthy application and connection, meaning no issues can be identified. During troubleshooting, I definitely need to visit the Insights and scoreboard to understand the level of connectivity the user is experiencing. Zscaler Digital Experience (ZDX) has positively impacted my organization by being beneficial for me as a troubleshooter and administrator, as I can identify all types of network performance-related issues, leading to faster resolutions of user complaints, improved collaboration between network, desktop, and security teams, and more productivity in identifying issues before they affect users. The outcome shows a 40 to 50% reduction in MTTR for SaaS applications and better SLA reporting for critical apps like Zoom and Salesforce, among many more applications which can be integrated with tenant authorization.
