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…

Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience

There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

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."

"The real-time troubleshooting and application segregation that you can do within it."

"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 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."

"The most valuable feature is utilization."

"The ability to troubleshoot customers' connectivity has been very beneficial."

"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's an easy product to set up."

More NETSCOUT InfiniStreamNG pros

"The ability to capture packets. It is not only for monitoring. That is very important for a company that wants to keep an eye on the packets, the transactions, the flows..."

"There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies."

"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"

"It can help to write your rules, organize firewalls, your block, and also your protocols and IP address to come in or out of your network."

"It's able to capture packets and, after a long time, you can come and use that information; to check, to analyze - everything you would want to do. So it's very good and helpful if you want to protect your data. It is stored in a certain place where you can access it every time you want to analyze it."

"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."

Cons

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

"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."

"Being able to manage the packet flow switches in nGeniusONE would be great."

"I'd like them to make the product more user-friendly."

"There is a timeout feature that we have been asking for awhile."

"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."

"The single pane of glass feed still needs work."

"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."

More NETSCOUT InfiniStreamNG cons

"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."

"I would like to have more than 4TB of storage available in the portable version of this solution."

"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."

"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."

Pricing and Cost Advice

"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."

"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."

"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 depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."

"It's quite expensive."
