EdwardShim

General Manager at MOCOMSYS

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.

Network Engineer at Inniti Network Solution

A user-friendly solution that is easy to install and improves visibility

I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

Quotes from Members

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

Pros

"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."

"From my user community, I am getting the impression that something which used to take days has now gone to hours for troubleshooting."

"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."

"From the standpoint of VoLTE and related things, it's providing visibility into the network and how it operates."

"Network faults are easily and quickly identified through dashboards and drill down."

"We are using nGeniusONE to run our bandwidth capacity management reports; in the past, we used to be very reactive and depend a lot on suppliers to tell us which sites are our hot sites with high bandwidth utilization, and now we do this in a much more proactive way and are moving to a more predictive approach in that aspect, thanks to nGeniusONE."

"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."

"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 nGeniusONE pros

"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."

"The generation of KPI-like information that feeds to the nGeniusONE (management) server is the most valuable feature."

"One of the valuable features is the packet decoding."

"Sometimes it took a month to troubleshoot something that we can now do within days."

"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."

Cons

"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."

"It needs a better GUI, and especially it needs to be more user-friendly."

"While it is good, the single pane of glass view is too high level. It is better for management or someone doing sanity checks."

"We see it overload once in a while. It doesn't have built-in protection."

"The product is a little complicated."

"We would like more encryption of customer data, because we have a very security conscious company. We have a lot of regulation coming in which requires us to make customer data private."

"The feature I am looking for is the Arbor technology, especially to run in parallel with our firewall."

"The initial setup was complex. It was hard to know what to tap and how to tap."

More NETSCOUT nGeniusONE cons

"I would like for it to have a smaller footprint of the virtual appliance and better performance."

"I would like to see improvements made to the user guide."

"I would like for it to have a smaller footprint of the virtual appliance and better performance."

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

"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."

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

Pricing and Cost Advice

"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."

"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."

"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."

"It is very expensive, but it's well worth the money."

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

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

"The scalability becomes very expensive quickly."

"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."
