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

"An issue that used to take days is now fixed within minutes to an hour."
"We are attracting customers in good sized numbers as we advertise and market this solution."
"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 packet flow switch is the most valuable aspect of the solution."
"The most valuable feature is utilization."
"It's an easy product to set up."
"If you are looking for a good application monitoring and packet analysis tool, you can strategically use NETSCOUT to get it done."
"This solution has saved us hours (three to four) per problem when troubleshooting."
"Network visibility is the most valuable feature."
 

Cons

"Sometimes, we can't access it."
"The stability depends on who is using the tool, because you only can get as much out of the tool as you put into it. There are a lot of patches for this particular environment, so you have to keep on them. If you lose track of them, then the product is not useful anymore."
"There is a timeout feature that we have been asking for awhile."
"The monitoring and reporting tool needs improvement."
"The single pane of glass feed still needs work."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"I'd like them to make the product more user-friendly."
"It can be scalable. It just costs too much."
"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."
"I would like it to be more scalable with less spend."
"The price is a little high."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"This product could be cheaper."
"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."
"It's expensive."
