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

"It helps us to assist our customers to isolate problems. If it is us who is having the problem, then we can use it to streamline the process."
"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."
"It's an easy product to set up."
"The most valuable feature is utilization."
"This solution has saved us hours (three to four) per problem when troubleshooting."
"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."
"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 helps us get to root cause quickly. With utilization and consumption of bandwidth, we can usually see what application is taking as much as they should (or shouldn't), then account for it accordingly."
"Network visibility is the most valuable feature."
 

Cons

"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."
"The solution is not great, but it is not bad."
"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 single pane of glass feed still needs work."
"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."
"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."
"I would like it to be more scalable with less spend."
"The price is a little high."
"It's expensive."
