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.

Pros

"I would advise others looking into using ThousandEyes to consider it one of the best tools for monitoring their network infrastructure."
"One feature I liked is end-user monitoring."
"With ThousandEyes, it's one click or one place where I can see all of my public prefixes, how long it takes, when the last update was, where a route was missing from the internet, or is it actually causing a black hole."
"The installation process is not hard at all."
"The most valuable features of ThousandEyes are the full monitoring capabilities and the ability to identify the exact location of problems in the path between the application and the end-user."
"<p>ThousandEyes is an excellent product that really provides accurate metrics into network performance as well as the user experience, and I would highly recommend it.</p>"

Cons

"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."
"ThousandEyes could be improved by unifying the GUI with the rest of the Cisco products since it remains legacy from its original state when Cisco acquired it."

"The first thing is that we don't have any option to export the reports."
"They only offer synthetic requests, so they should create an agent for users that can track your request."
"I feel it needs more holistic integration. It needs more improvement."
"We can show the traffic path in some cases, but it's almost impossible to do so in cloud networks like CDN, Akamai, or Microsoft."
"I would like the product to offer more agility."
"Support responses are excellent, but for more complex cases, it sometimes takes longer."
"Zscaler Digital Experience (ZDX) is comparatively an expensive product."
"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."
