Monitoring has improved bandwidth insights and application diagnosis but setup and costs still need work

They need room for improvement about the spare parts. There are shortages in Egypt in their stock. We tried to make RMA for specific parts, and it took a long time. Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time. This needs more improvement. I believe it is expensive. They need to reduce its budget a little bit. Comparing to other solutions, it is very expensive.

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.

Quotes from Members

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

Pros

"I like the single pane of glass view because it presents everything in one window, obviously. You can see it all. With a quick glance, you get a pretty good snapshot of what's going on in a particular situation."

"When we can get the data into the tool, we absolutely see a decrease in mean time to know and mean time to repair, and similarly for overall troubleshooting time."

"With the Vprobes, we quickly identified issues on the application servers, which we normally couldn't, where it usually would be a full circle round between our NOC and server people."

"Go with NETSCOUT."

"The product is very good. We have very few problems."

"Whenever there is an outage, it's quickly able to identify it and, without pointing fingers, we can prove that it is not the network environment."

"NETSCOUT nGeniusPULSE has an easier dashboard to manipulate compared to SolarWinds."

"Among the valuable features, if it's TAP'ed well, are the density of the data that you can get and the relatively high veracity or accuracy rate that we see from it."

More NETSCOUT Network & Application Observability pros

"Regarding the benefits of Zscaler Digital Experience (ZDX)'s traffic analysis for my IT operations, I believe it greatly supports our needs."

"Zscaler Digital Experience (ZDX) positively impacted my organization by providing Zero Trust Network Access, which many organizations are moving towards."

"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

"This is a typical thing, but every time they do a major code upgrade, we get hit with some nasty bugs. Some of them literally stop the whole platform from collecting traffic data. They should really do more Q&A on the software stability before release."

"I would say that this is not a scalable solution."

"They require a lot of manual effort as traffic flows, networks, and formal times change."

"It's not able to communicate with our probes."

"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."

"Between the host analysis and session analysis, there is a limitation of one hour. This can hinder us if a situation occurred ten hours ago."

"Maybe the optics cost could be improved. It's not about the product itself, but the optics cost from other companies is very high, which affects the business. When you buy a $1 million product, you shouldn't be expected to pay $500,000 for support. So, support, operation, and professional services are very expensive. It's the main weakness."

"Room for improvement exists in filtering in the packet decode."

More NETSCOUT Network & Application Observability cons

"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."

Pricing and Cost Advice

"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."

"Their pricing is very competitive with other solutions... But what I like about NETSCOUT's licensing is that it's shared across all their platforms. They don't create a new licensing scheme for every one of their products. So for nGeniusONE, you buy a certain license level, and it works on all of their products."

"If you are able and you are willing to use everything that Netscout provides to you, it's probably a relatively fair price. The problem is that it's such a large and such a complex tool that I'm not sure that many companies would be able to use it entirely, the way it's expected to be used."

"There is a need to make yearly payments towards the licensing charges attached to the product. The product may come across as a cheap tool for some, while it may seem costly for others."

"The price is only for acquisition; it's not a licence."

"The platform is expensive."

"Cost is probably the biggest drawback. Compared to some of the newer vendors that have popped up in the space, it's definitely more on the expensive side... [But] it's been able to keep its value, even in the face of the cheaper competition."

"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
