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",…

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 solid solution that can be easily deployed then I'd recommend considering Netfort solutions."
"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."
"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."
"This solution has saved us hours (three to four) per problem when troubleshooting."
"When we have mobile operators who are signal partners, where one is the roaming host and another is the roamer, we are able to see their traffic. Their packets are able to detect if any faults to develop, and at what point they fail."
"The real-time troubleshooting and application segregation that you can do within it."
"It's an easy product to set up."
"The packet flow switch is the most valuable aspect of the solution."
"The ability to troubleshoot customers' connectivity has been very beneficial."
"Go with NETSCOUT."
 

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 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."
"We don't use the single pane of glass view, even though we own it."
"There is a timeout feature that we have been asking for awhile."
"The single pane of glass feed still needs work."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"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."
"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
"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."
"I would like it to be more scalable with less spend."
"The price is a little high."
"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."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
