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

"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."

"If you are looking for a solid solution that can be easily deployed then I'd recommend considering Netfort solutions."

"If you are going to implement NSX, it's a great tool."

"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."

"I love what we can do with this and I love everything it gives to us."

"This tool is critical because from a VMware perspective, it's really the only tool that does application rationalization."

"I would definitely advise, especially healthcare companies that need to secure their products, NSX using vRNI as their tool."

"We get proper reporting on different aspects such as utilization and health monitoring reports, including throughput details and network latency, and there are many things we can obtain from there."

"It allows us to see how the network devices function as well as to see network glitches or fluctuations or dropping of packets."

"If we can get it to provide those firewall rules it will literally save hundreds of man-hours, if not thousands of man-hours."

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."

"We're still going through the learning pains so we haven't quite got out of it most of what we're looking for, yet."

"Technical support has been responsive. The response has always been immediate. Whether or not they've fixed it immediately is a different story."

"In a very general way, I would like to see an improvement in interoperability with third-party product, from other vendors."

"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."

"In a very general way, I would like to see an improvement in interoperability with third-party product, from other vendors."

"There could be some deeper analytics into packet inspection and trace flows. It could use some kind of machine learning to look at Layer 7 traffic for potential malware or corrupt packets."

"I'd like to see better support for being able to search the hardware NetFlow data."

Pricing and Cost Advice

Information not available

"I rate vRealize Network Insight's pricing a seven point five out of ten."

"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."

"The solution has helped us to reduce time, increase performance, reduce costs, and even easily manage networks. We are probably seeing 10 to 20 percent labor savings because we are able to be very specific and focused on what we want to do. It ends up saving the customer money and makes us be more efficient on our cost deliveries."

"vRealize Network Insight is expensive."

"We have spent less time investigating network flows, so it is absolutely cost-effective."

"They should include the product in NSX because it's important to have it for deployment."

"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."

"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."
