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…

A user-friendly solution that is easy to install and improves visibility
I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

Quotes from Members

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

Pros

"It has cut our troubleshooting down by days. Once we have a product in place, we show people examples of how it can streamline their troubleshooting process."
"The most valuable features are speed and cost."
"An issue that used to take days is now fixed within minutes to an hour."
"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."
"This solution has saved us hours (three to four) per problem when troubleshooting."
"The packet flow switch is the most valuable aspect of the solution."
"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."
"It has cut our group's troubleshooting time down significantly, e.g., depending on the issue, what would normally take maybe a couple of hours will now take minutes."
"One of the valuable features is the packet decoding."
"Sometimes it took a month to troubleshoot something that we can now do within days."
"The generation of KPI-like information that feeds to the nGeniusONE (management) server is the most valuable feature."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
 

Cons

"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 monitoring and reporting tool needs improvement."
"I'd like them to make the product more user-friendly."
"The NetFlow Collectors could handle more flows per minute."
"Sometimes, we can't access it."
"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."
"It can be scalable. It just costs too much."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"I would say that this is not a scalable solution."
"Room for improvement exists in filtering in the packet decode."
"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."
"I would like to see improvements made to the user guide."
 

Pricing and Cost Advice

"This product could be cheaper."
"The price is a little high."
"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."
"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."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"Licensing is quite expensive."
