Monitoring has transformed internet visibility and speeds up resolving external service issues
ThousandEyes needs to specify unit consumption forecasting or scaling testing and deeper app analytics. It needs deeper out-of-the-box Layer 7 code or database-level insights. Additionally, it should unify the GUI with broader Cisco platforms and flatten the learning curve, adding better correlation with local laptop system metrics such as endpoint depth, CPU, RAM, or processes. ThousandEyes isn't designed to be a full-blown SNMP monitoring tool for on-premises infrastructure. While it tracks network paths effectively, it doesn't provide deep local device telemetry such as switch port buffer utilization, fan status, or power supply health. For full internal device monitoring, you'll still need to pair it with traditional tools such as SolarWinds or Cisco Catalyst Center.

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.

"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."

Cons

"ThousandEyes could improve the dashboards by adding more features."
"I feel it needs more holistic integration. It needs more improvement."
"I chose a six out of 10 because it lacks monitoring features for application performance and database monitoring, especially end-user experience; it excels mainly in network performance monitoring and network device monitoring."
"ThousandEyes could improve by implementing a similar incident management system like BigPanda or ServiceNow."
"Cisco is the standard for anyone wanting something good, the problem with it is the cost and that means that it's not accessible to many smaller companies."
"It might be practical to extend monitoring capabilities to include network devices"
"ThousandEyes definitely has differentiators versus the peers in the space, as there are other tools that are a bit more user-friendly to configure, especially around enterprise agents; for example, when upgrades are required, it sometimes needs a complete de-installation and re-installation of a newer version, which leads to a bit of administrative overhead from time to time, but overall, it has been an excellent product."
"There is room for improvement in terms of customization and user-friendliness."
"I have noticed drawbacks within Zscaler Digital Experience (ZDX), as the sales team is too arrogant and too aggressive, playing politics, but the product itself is very good."
"Support responses are excellent, but for more complex cases, it sometimes takes longer."
"Zscaler Digital Experience (ZDX) is comparatively an expensive product."
