Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

Quotes from Members

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

Pros

"If you are looking for a good application monitoring and packet analysis tool, you can strategically use NETSCOUT to get it done."
"The real-time troubleshooting and application segregation that you can do within it."
"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."
"Because we are doing proactive monitoring instead of reactive, the end users don't even see that there is something wrong."
"The product is stable. I have never had any issue where we have lost an InfiniStream, or visibility from that particular InfiniStream, throughout the bank."
"This solution has cut our overall troubleshooting time, sometimes going down to a few hours over what might have taken one to two days to fully troubleshoot an issue, and it has helped to increase our application uptime as we try to keep the five nines."
"I love the single pane of glass view. It makes it easier to not have to navigate everywhere. It allows more simplistic visibility, without having to go from tool to tool to tool, or from window to window to window."
"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."
"Network visibility is the most valuable feature."
 

Cons

"The NetFlow Collectors could handle more flows per minute."
"Sometimes, we can't access it."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"It can be scalable. It just costs too much."
"I'd like them to make the product more user-friendly."
"It's not able to communicate with our probes."
"The monitoring and reporting tool needs improvement. Users want more information, such as the level of detail when doing a packet analysis. They want more detail to be able to isolate down to a specific point."
"I'd like them to make the product more user-friendly."
"The pricing and AI can be improved."
 

Pricing and Cost Advice

"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"This product could be cheaper."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"I would like it to be more scalable with less spend."
"The price is a little high."
"It's expensive."
