Newwork And Collaboration Supervisor at Nafeza
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.

Director at Bitrate
Has good network visibility
The primary use case is for monitoring and troubleshooting. We also use it for security.   The correlation of data in Apex helps to get full visibility of the entire enterprise. Apex is where we get the end-user experience score from one to ten. Network visibility is the most valuable feature.…

Quotes from Members

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

Pros

"It has cut our group's troubleshooting time down significantly, e.g., depending on the issue, what would normally take maybe a couple of hours will now take minutes."
"The best feature is when we have it connected permanently via TAPs. That enables us to constantly collect data and then we can go back in time... To be able to rewind, back in time, and see the problem as it happened, is very helpful."
"Technical support for this product has been ok, with no issues."
"This solution has saved us more than $50,000 a month and freed up 30 percent of our bandwidth."
"It is a scalable product."
"The most valuable features are speed and cost."
"The visual and graphical interfaces in the display that it provides for us to show our senior leadership. We can show them what is actually happening, instead of a spreadsheet."
"Other than those bugs I mentioned, we haven't encountered any issues with stability."
"Network visibility is the most valuable feature."
 

Cons

"It needs a better GUI, and especially it needs to be more user-friendly."
"I would like more in-depth convergence between all the applications, especially when I look for information through a data mine."
"The solution is not easy to install."
"I would love to have them reassemble fragmented packets. That would be a very big plus in my book."
"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."
"On a network the size of ours, the loading times seem a little extensive, 20 or 30 seconds to load up some graphs."
"The initial deployment is tedious and requires a lot of build, deployment and configuration time. Experience is key to a successful deployment."
"A lot of tools highlight what's going on but they don't actually pinpoint the user experience. It would be good if there were a small message or something highlighting what the user experience is like and any degradation that's actually occurring."
"The pricing and AI can be improved."
 

Pricing and Cost Advice

"The price is a little high."
"Like any company, we always want better pricing. The pricing is okay, but it's not a cheap solution. When you want to deploy it across an enterprise as large as ours, you go into seven figures. It's not a cheap solution to get out there."
"We have a premium customized contract for the solution."
"It can be expensive, but if you have a good configuration, based on what you are looking for, it's okay, it's manageable."
"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."
"It is a little overall pricey and expensive, but you get what you pay for."
"It is very expensive, but it's well worth the money."
"I would like it to be more scalable with less spend."
"It's expensive."
