Abdalraheem Asha - PeerSpot reviewer
Senior cloud engineering lead and IT project owner at KDD
Has improved collaboration with providers and pinpointed issues across regional networks
ThousandEyes has been the most user-friendly tool I have seen in the past couple of years, making life easier in troubleshooting and helping us find what's happening while offering vivid options on how to use the agents or the server-side tools with multiple options to trace out the issues. The best features ThousandEyes offers include the ability to place two different points or nodes, such as a server or a node in the cloud in my account, then installing agents and tracing the connectivity which helps me build a perfect user experience to check what's happening while users access my resources. I love the dashboards in ThousandEyes and the way I see the results after placing or doing the tests; this is perfect, and I would say this is the best thing. ThousandEyes has positively impacted my organization by raising the customer experience and positive feedback by over 70% due to the complex situation with local service providers, allowing me to resolve user feedback and issues which enhanced the user experience significantly. I measure the 70% improvement in customer experience through customer tickets and feedback after resolving issues, where previously, users faced problems and limited time on the platform, and after using ThousandEyes, the user time reached up to five to six hours a day, even for teams possibly totaling 30 hours a day.

Offers steady access and reliable support but could benefit from better integration and user-friendly insights
Regarding future updates, I would like to see Zscaler prioritize pricing and integrate more with multiple products. Multiple integrations with various platforms would enable some sort of automation. Zscaler provides real-time insights, but it is not reaching the end users properly, which is something Zscaler should improve because it should be user-friendly for understanding what Zscaler is offering. When there is too much technology, people cannot understand it, so it should be very simplified, and there should be some ways for users to gain knowledge about the product themselves. Zscaler's ability to analyze millions of telemetry data points in real-time is still somewhat unclear to me; perhaps that level of knowledge has not been reached by me or the end users, indicating that Zscaler has to focus on that area.
