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.

The product is extremely valuable and provides a lot of functionalities and visibility to organizations
The score-based application performance ratings help the network team. Often, customers have a siloed environment for security, applications, and servers. The network team is always asked to do troubleshooting. Being able to know how well an application worked in the past and what's happening today is really helpful. If someone has a complaint and the network team says that the problem is not on their side, they must be able to demonstrate it accurately. The network team is often given the least budget and the least number of employees. So, they must be able to troubleshoot and pinpoint problems as fast as possible. If it’s a network issue, they must fix it. However, if it is a cloud problem, an ISP problem, or a problem within the server or application environment, they must be able to demonstrate it clearly. It is the real benefit they get from the solution. Some of our customers are financial institutions. They use the tool for traffic accounting, especially when they get charged by ISPs or carriers for the amount of traffic they are using. In South Africa, we have banks that pay the service providers to allow customers to use their banking apps for free. The bank pays for it, not the customers. So, they need to compare to ensure they are paying for what has been used. Viavi enables them to do that. It is pretty much the best there is in the world. There is nothing to beat it. The product is extremely valuable and provides a lot of functionalities. It's really impressive.

Quotes from Members

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

Pros

"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."
"We have cut back on our troubleshooting, by isolating certain trouble areas."
"The solution gives us increased visibility while conducting an IT deployment, recording data all the time so we have the before picture and the after picture, and in areas where we have instrumentation, we have seen a measurable decrease in mean time to know and mean time to repair."
"The details it provides are among the most valuable features; the ability to drill down and get to the packet level."
"The VoLTE model, call search and Media Monitor were essential when we launched VoLTE. We're relying heavily on them to troubleshoot our VoLTE calls."
"It is an easy-to-scale platform."
"The tool itself is just fantastic."
"Aside from having the logs that are just on the firewall, we're able to get the traffic as it's going in between, throughout our network. It isolates end sources that are having issues, where we don't have any other tools that would be able to go down to an end-user's computer to find out what's going on."
"The score-based application performance ratings help the network team."
 

Cons

"It would be beneficial to see more AI capabilities included in nGeniusONE to further streamline processes and allow lower-level tech support to handle issues more effectively without escalating them."
"Its initial setup process is complicated."
"It's not an easy system, it's a very technical system."
"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."
"The stability depends on who is using the tool, because you only can get as much out of the tool as you put into it. There are a lot of patches for this particular environment, so you have to keep on them. If you lose track of them, then the product is not useful anymore."
"I would like to see an improved level of stitching between IPs."
"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."
"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."
"The product must start using a bit more machine learning and AI, especially for security."
 

Pricing and Cost Advice

"I don't know what the cost to buy the solution was, but I doubt if it's a significant part of the budget as far as the maintenance and support are concerned."
"We have a premium customized contract for the solution."
"This product could be cheaper."
"It is very expensive, but it's well worth the money."
"The tool's price is okay. On a scale of one to ten, I rate it as a five, where one means it is not expensive, and ten means it is the most expensive."
"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."
"The price is only for acquisition; it's not a licence."
"Licensing is quite expensive."
"The tool is very pricey."
