ES
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 solution transforms packet wire data into real-time data that is actionable. It helps us with faster detection of issues and allows us to create alerts."
"Packet decode and bandwidth analysis reports are the two most valuable features."
"The installation process is straightforward."
"We are using nGeniusONE to run our bandwidth capacity management reports. In the past, we used to be very reactive, we used to depend a lot on suppliers to tell us which sites are our hot sites, meaning, which have high bandwidth utilization. Now we do this in a much more proactive way and we are moving to a more predictive approach in that aspect, thanks to nGeniusONE."
"The most valuable feature of NETSCOUT nGeniusONE is it helps customer to understand what risks are in their network. For example, if a customer has some wrong configurations. It could cost them some critical services to slow down."
"The product is very good. We have very few problems."
"Stability-wise, I rate the solution a ten out of ten."
"Deep packet inspection is a very useful tool as it works in real time and uses serial packet-level analysis."
"One of the valuable features is the packet decoding."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
 

Cons

"The product was lacking for awhile when they did the Arbor acquisition. I was waiting to see more security stuff, which they did eventually add, and is now impressive."
"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."
"Datadog is more stable than NETSCOUT nGeniusONE, being a SaaS-based solution compared to on-prem solutions like NETSCOUT."
"The current solution is not easy to scale, because it is an appliance-based solution. So, you have to swap everything out."
"The solution is not easy to install."
"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."
"The product is a little complicated."
"NETSCOUT nGeniusONE's pricing is higher compared to the competitors. It is more than 15-18 percent of competitor costs. It also needs to add AI features."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"Room for improvement exists in filtering in the packet decode."
"I would like to see improvements made to the user guide."
 

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."
"The product is too expensive compared to other products."
"It is very expensive, but it's well worth the money."
"It is a little overall pricey and expensive, but you get what you pay for."
"I rate the price of NETSCOUT nGeniusONE a four out of five."
"This solution has saved us more than $50,000 a month and freed up 30 percent of our bandwidth."
"The license becomes cost prohibitive very quickly."
"The biggest problem we have with this product is the expense."
"Licensing is quite expensive."
