Offers detailed network monitoring but requires improvement in deployment complexity and pricing

The price is really high, making it difficult for many financial companies to purchase immediately; it will take time for them to afford any budget for the purchase. The traffic data correlation feature's effectiveness with performance issues for clients remains uncertain as there are questions that need to be addressed through engineers regarding how many customers are actually using it. Regarding pricing and value for money, while the solution has the potential to save time and money for clients in the long term, monitoring solutions for performance management or network monitoring do not cause immediate damage to a company. It could lead to damage over time, but financial and management teams typically cannot see the immediate crisis. This is why many big companies Samsung and Hyundai try to build their own monitoring solutions using open-source tools and their own engineers, though it has not been successful.

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

"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."

"This solution provides us with increased visibility while conducting IT deployments. E.g., if we have devices which have overloaded or links which have saturated, then this tool tells us exactly what is going on with that link or device. Very few tools do it at this level for things like DDoS."

"It catches bigger issues on a weekly basis. That's how often we find something big enough that the only reason we know about it is because of the nGeniusONE. The bigger issues are mostly security-type issues: Odd traffic leaving our network or coming into it, that has found its way past a firewall."

"Deep packet inspection is a very useful tool as it works in real time and uses serial packet-level analysis."

"The valuable features include packet analysis, packet capture, and [that] it's easy to use."

"The most valuable features are visibility, real-time, on-demand."

"It is the ability to collect data and analyze it, especially key performance indicators. This is before a customer would call to the service center to complain that they have had bad coverage or a dropped call."

"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."

More NETSCOUT nGeniusONE pros

"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"

"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."

"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."

"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 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..."

"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."

Cons

"The solution could do more for security. It should offer more security-related features."

"There is currently less visibility or GUI to analyse the packet for troubleshooting purposes."

"On a network the size of ours, the loading times seem a little extensive, 20 or 30 seconds to load up some graphs."

"The stability is only fair. It goes down a lot."

"Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time."

"NETSCOUT nGeniusONE can improve the detection of what area of the infrastructure could be having an issue, such as an application, server, or network. It needs to find evidence of a fault."

"It's not intuitive, it's not simple to use. It is probably the only monitoring tool, out of all the ones that I have, that I really need an expert on, an expert from nGenius, a contractor that I have to pay, to manage the tool. And that's because it's simply not easy to use. Netscout needs to focus on making it easier to use."

"While it is good, the single pane of glass view is too high level. It is better for management or someone doing sanity checks. A lot of times, I need to go deeper into the additional screens to get what I want out of it."

More NETSCOUT nGeniusONE cons

"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."

"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."

Pricing and Cost Advice

"Make sure you get the low down on your licensing and understand the licensing requirements before making a purchase, especially when it comes to an upgrade. Make sure that it suits your needs before you commit to it. For example, we purchased ATA at version 6.2.1. At that time, the licensing covered everything we need. NETSCOUT comes out with 6.2.2, stating that in order to upgrade, you had to purchase CyberStream licensing. Now that requires some additional funding from both a capital investment and a maintenance cost. That's something that should have been said, "Well, if you want these additional features, you will need to purchase these CyberStreams." Otherwise, we should be allowed to continue on the basic operations as it is now through the newer releases without being stuck."

"Licensing is flexible, it's not tied to anything else. We can easily switch up the licensing piece... Obviously, NETSCOUT is a little bit in the higher range, but it gives you value for money. You get what you pay for."

"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."

"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 biggest problem we have with this product is the expense."

"The product is too expensive compared to other products."

"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."

More NETSCOUT nGeniusONE pricing and cost advice

"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."

"It's quite expensive."
