Shreyans Parekh - PeerSpot reviewer
Vice President, Finance and Operations at Fruitist
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.
Chella  Chalapathi - PeerSpot reviewer
Senior Technical Program Manager at Infosys
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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"One feature I liked is end-user monitoring."
"ThousandEyes offers the best features including global internet and cloud visibility from distributed vantage points, application and network performance monitoring, real-time outage detection and incident alerts, end-to-end path visualization for rapid troubleshooting, proactive issue demarcation, and historical data."
"The solution's most valuable feature is network security."
"For me, all the features are great and make ThousandEyes stand out among other observability products."
"The solution is very easy to use."
"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."

Cons

"I feel it needs more holistic integration. It needs more improvement."
"More detailed documentation explaining the metrics and the testing mechanisms would be helpful."
"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."
"Once I fully use the tool 100%, I'm sure I would have something to critique, however, for now, I'm happy with it."
"They only offer synthetic requests."
"ThousandEyes should expand its application monitoring to monitor some communication applications."
"It's an expensive solution."
"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 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."
 

Pricing and Cost Advice

"The solution is cheap."
"In our company, we incur a yearly expense in our company for the licensing part. I rate the solution's pricing a seven out of ten since it is expensive."
"It is a quite expensive solution."
"The solution's pricing is cheap; I rate it a five out of ten."
"The solution costs several thousand dollars per year."
