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.

Keval Lodaya

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

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

"The biggest advantage of NETSCOUT nGeniusONE is that when gathering logs, which require substantial bandwidth of more than 50 TB or 100 TB of data, NETSCOUT nGeniusONE can gather as much as possible."

"For me, the most valuable features are the dashboards which we use to highlight the overall impact to the customers, and being able to drill down into the nitty-gritty of the customer experience."

"When we have any type of outage, and we dig into it, we are able to tell what the root cause is instead of having to go through Wireshark, etc."

"The real-time insights that NETSCOUT nGeniusONE provides are very helpful."

"The details it provides are among the most valuable features; the ability to drill down and get to the packet level."

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

More NETSCOUT nGeniusONE pros

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

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

Cons

"They can improve still on the workflows, document their workflows that are commonly used... We don't know some of the workflows yet, and it's not something that you can just read up in the manual. There is some stuff in the help manual and online, but it's to a point where you need to purchase extra training and services from them. You can't just go and read up on it yourself and learn from A to Z..."

"Some help screens would be nice, especially if we bring on new operators. It would be great to see if they have more helpful tips available."

"The technical support could improve a bit with quicker responses for early on questions. What I think are simple questions are taking a long time to get answers to."

"This is a typical thing, but every time they do a major code upgrade, we get hit with some nasty bugs. Some of them literally stop the whole platform from collecting traffic data. They should really do more Q&A on the software stability before release."

"nGeniusONE could be improved by reducing the number of bare metal servers required to run it. Currently, you need a separate bare metal server for each of the following: Xfinity, ISNG, nGeniusONE, and CFS. It would be more cost-effective and less complex if all of these functionalities could be combined into a single bare metal server."

"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 could have an easier to understand interface."

"The dependency mapping is good, but I am hopeful that they will build some type of partnership and relationship with ServiceNow. I want to see NETSCOUT partner with ServiceNow so they can leverage Service Now Discovery and Service Mapping to automate the build of the service dependency mappings inside of nGeniusONE."

More NETSCOUT nGeniusONE cons

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

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

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

Pricing and Cost Advice

"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."

"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."

"The license becomes cost prohibitive very quickly."

"It can be expensive, but if you have a good configuration, based on what you are looking for, it's okay, it's manageable."

"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."

"This solution has saved us more than $50,000 a month and freed up 30 percent of our bandwidth."

"It is a little overall pricey and expensive, but you get what you pay for."
