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.

Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience
There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

Quotes from Members

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

Pros

"We have seen a measurable decrease in mean time to know and mean time to repair, and because the tool allows us to get to things a lot quicker and see things a lot quicker, we have actually reduced those times and it has definitely helped with our network uptime, with an improvement in uptime of at least 50 percent."
"The product is very good. We have very few problems."
"From a troubleshooting perspective, it allows us to quickly search all data TAP points in the network and helps our network engineers get to root cause quickly."
"Valuable features include data threat detection, network analytics, and overall bandwidth monitoring."
"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."
"The support is good."
"If a lot of traffic from one site is hitting AWS Cloud or the data center, then we want to know which client is utilizing the most bandwidth. We will work with nGeniusONE to troubleshoot the issue."
"Proactive versus a customer having a bad experience: That is the key point."
"Go take a look at it. It's a great product and has great capabilities."
"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."
"The ability to capture packets. It is not only for monitoring. That is very important for a company that wants to keep an eye on the packets, the transactions, the flows..."
"It's able to capture packets and, after a long time, you can come and use that information; to check, to analyze - everything you would want to do. So it's very good and helpful if you want to protect your data. It is stored in a certain place where you can access it every time you want to analyze it."
"I have no regrets using this product, I am very satisfied for what I paid for it and for the things I am able to do with the product."
"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"
"If you have the opportunity, I would strongly encourage you to get it, because it makes the IT experience easier and more flexible, by providing the ability to see things in your networks like the directory packet label."
"It can help to write your rules, organize firewalls, your block, and also your protocols and IP address to come in or out of your network."
 

Cons

"They can increase flexibility in the search engine. Basically, I go with the information I have at the time. If I could just type in the parameter that I want to search for and its value, it might be easier than having to do the groundwork upfront before I can get my traces."
"The GUI has gotten better over time but there could be some improvement in how the GUI is built."
"Sometimes the network analyzer will show that a server is down when it's actually working."
"They require a lot of manual effort as traffic flows, networks, and formal times change."
"NETSCOUT nGeniusPULSE is not integrated with SolarWinds. They work in different ways."
"NETSCOUT nGeniusONE is a complex product since it deals in areas like network packet brokers and packet analysis, making the tool complicated for end users."
"In terms of additional features, I would like to see better event notification. Right now, we put in an email address to receive an alert and it receives every event and every alert that comes out. We need something a little more granular."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"I would like to have more than 4TB of storage available in the portable version of this solution."
"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."
"There are some issues, in our environment that puts processing restraints on the Gigastor when turning on trending data to be sent to APEX."
"The Observer Console UI is consistent and stable, but could use some updating to be more modern."
"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."
"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."
"The interface is pretty complex, so for the average user, it takes a while to get up to speed with it. I would like it to be more user-friendly."
 

Pricing and Cost Advice

"The price is only for acquisition; it's not a licence."
"The biggest problem we have with this product is the expense."
"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."
"I would like it to be more scalable with less spend."
"It was pretty modest because you could get it in different ways. I think the six licenses, at that time, were about $1,000 each. But then again, I work for a school and educators tend to get discounts on things. So maybe it cost us about five or six hundred a copy."
"It is very expensive, but it's well worth the money."
"I rate the price of NETSCOUT nGeniusONE a four out of five."
"We have a premium customized contract for the solution."
"It's quite expensive."
"It depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."
