Cost effective but when we originally purchased LANGuardian, some features needed further development.

The ability to detect and decipher torrent traffic for the purpose of identifying what some refer to as "copyright violators" Our CIO asked us to track down the source of undesired uploads, which trigger e-mails received by outside bodies regarding what they refer to as "copyright violations",…

Quotes from Members

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

Pros

"Our CIO asked us to track down the source of undesired uploads, which trigger e-mails received by outside bodies regarding what they refer to as "copyright violations", and Languardian was the most efficient and effective tool for the job."

"If you are looking for a solid solution that can be easily deployed then I'd recommend considering Netfort solutions."

"It is very rock solid. We hardly have any hardware issues."

"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."

"We use it for monitoring whenever we update a new circuit or site."

"It's an easy product to set up."

"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."

"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."

"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."

More NETSCOUT InfiniStreamNG pros

Cons

"It takes a long time to load results. I think it would be great if they fix the slowness issue in the next release."

"Sure, at the time we bought the product, the GUI and graphs/reports/pie charts etc ... were not fully developed."

"The NetFlow Collectors could handle more flows per minute."

"We don't use the single pane of glass view, even though we own it."

"The NetFlow Collectors could handle more flows per minute."

"It's not able to communicate with our probes."

"The monitoring and reporting tool needs improvement."

"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."

"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."

Pricing and Cost Advice

Information not available

"This product could be cheaper."

"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."

"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."

"The price is a little high."
