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

"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."
"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."
"Go with NETSCOUT."
"This solution has saved us hours (three to four) per problem when troubleshooting."
"If you are looking for a good application monitoring and packet analysis tool, you can strategically use NETSCOUT to get it done."
"We use it for monitoring whenever we update a new circuit or site."
"The most valuable feature is utilization."
"The solution has helped to increase application and network uptime, reduced our mean time to repair significantly for application and network issues, and cut our overall troubleshooting time from an hour down to five minutes."
"Network visibility is the most valuable feature."
 

Cons

"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."
"I would like to see an improved level of stitching between IPs."
"The single pane of glass feed still needs work."
"The solution is not great, but it is not bad."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"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

"I would like it to be more scalable with less spend."
"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."
"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."
"This product could be cheaper."
"The price is a little high."
"It's expensive."
