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",…

Comprehensive management and detailed reports benefit operations while improvements are needed in support and maintenance
We have Tanzu and OpenShift. We have OpenShift, Canonical, and the Tanzu one. The Tanzu platform from VMware is a Kubernetes platform. We haven't completely installed Tanzu yet; we installed the vROps part. vRealize Network Insight is beneficial because you can control the East-West traffic. vRealize has a component called NSX, which has East-West traffic controlling and micro-segmentation, that is one of the best options, and we have the layer extension, layer 2 extension possible through NSX. If you have anything accountable in any business, even in a candy business, having proper accountability on what you are selling and buying will save a lot. If you don't know what you're selling and buying, you will end up with a loss. My team does not use the flow analytics feature; we have a security and network monitoring team, which is a different SOC team. I am using it as an administrator internally. We perform different tasks including costing analysis, capacity management, and many other things. vRealize Network Insight has a concern about the maintenance part, as it requires a person to monitor it completely. It's not something you install and your report will be generated automatically. You have to work on this properly to get the insights. vRealize Network Automation, vRealize Operations, and vRealize Network Insight are completely related to the network. I cannot say much about these network aspects because I am on the operations side, but overall, the vRealize suite is good for reporting perspective or any ISO-related documentation; this is very helpful. The product is called vRealize Operations Manager, and now it is referred to as Aria or vAria. I am now a Senior System Specialist. We use different metrics because we have multiple departments, and we can monitor utilization and comparisons with the previous year. On a scale of one to ten, I rate this solution a seven.

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."
"I would definitely advise, especially healthcare companies that need to secure their products, NSX using vRNI as their tool."
"The most valuable feature is the visualization, as it is really handy to be able to classify network objects with applications and see the interaction between them."
"It allowed us to set up NSX and to do microsegmentation, without all of the pain points of having to determine each port and each IP address that needed to have access, and which ones needed to be blocked."
"It has enabled us to set up and do application discovery, as far as network traffic is concerned, and set up the appropriate rules that we need to make sure we're compliant with our security frameworks."
"It helps a lot because, until now, we didn't have the tools to figure out the micro level, VM-to-VM kind of traffic; that was not in the current environment. We could not figure out VM-to-VM communication from the other tools. This is the tool which gives us end-to-end transparency."
"The most valuable features are the packet trace flow and that the view of the whole environment is deep."
"compare-to-competition; I would recommend the product. I don't think there is any other product like this on the market right now."
"Previously, we had no idea how the dataflow worked. We knew how all the applications and servers worked, but we never knew how the dataflow was happening."
 

Cons

"Sure, at the time we bought the product, the GUI and graphs/reports/pie charts etc ... were not fully developed."
"It takes a long time to load results. I think it would be great if they fix the slowness issue in the next release."
"Price. Honestly, the way it's licensed is challenging."
"Support could be much better."
"I'd like to see better support for being able to search the hardware NetFlow data. It ingests fairly well, but you can't tell, in a lot of cases, what source the data came from. I'd like to see more support for picking specific sources. That way you could really make a compelling use case. There are also some difficulties where it can't exactly trace the path between source and destination but if you hit the reverse flow on the same search it shows the entire path."
"The UI, even though once you get to know it, it's easier, still it's hard to figure out by yourself. You have to go read, watch videos. It has a lot of data on it. So that is an issue."
"vRNI needs more remediation where it hooks into NSX."
"The pricing is steep."
"If it had some kind of plugins with vSphere, more effective plugins with Horizon View or other VMWare products, if it had interconnectivity, I think it would be more effective than it is today."
"Technical support has been responsive. The response has always been immediate. Whether or not they've fixed it immediately is a different story."
 

Pricing and Cost Advice

Information not available
"It reduces costs. It takes something that may be challenging and makes it more usable and visual by being able to bring in tools, seeing what their impact is, such as microsegmentation and application rationalization, and seeing it quickly."
"It's an expensive product because we have a lot of nodes."
"Cost always has room for improvement, you could always make it cheaper. But I think it's a good value for what you pay for it."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"It has brought more money into our company."
"They should include the product in NSX because it's important to have it for deployment."
"It's a little expensive, but for what you're getting out of the product, you often see the trade-off. It depends on the type of licensing you have. It might be a little too pricey for some."
"The solution has reduced the time that we spend on other products. For example, with NSX, we were able to quickly find things that we would normally spend days trying to figure out."
