Improves network monitoring and offers insights into traffic, including VPNs
The real-time reporting feature of Nmap is particularly valuable. It generates detailed reports on the source and destination IP addresses, the protocols used, and the types of traffic. This feature is crucial for law enforcement agencies to monitor and analyze network connectivity effectively. It also has traffic analysis. For example, assessing bandwidth usage and configuring the tool to track specific types of traffic is crucial. Unlike SolarWinds, which requires configuration for this, Nmap has built-in functionality that allows it to check all 4,000 computer ports. It identifies the type of traffic each port is using and can easily generate reports on network communications between computers, whether there are 100 or 1000 in the network.

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

"It helps us secure the network infrastructure."
"Nmap is mostly helpful during compliance checks. We run the scanner to see how many devices are on our network and find vulnerabilities in those that aren't compliant. We also use it monthly to scan our network and identify devices that aren't connected properly. This helps us detect any issues related to the operating systems of these devices."
"The initial setup was simple."
"Nmap's performance is great, and I've never noticed any issues in this respect. It really doesn't put a heavy load on the machine when using it."
"The scanning procedure includes UDP ports which sets it apart from competitors."
"The solution detects the operating systems, which makes testing the software much easier before making the payload."
"The best feature of Nmap is that it lets me see useful information about each endpoint in my entire network environment. For example, I can see every single connection of the network as well as each and every port."
"Nmap has a powerful command line tool and a set of diagnostic features."
"It allows you to see traffic that you couldn't otherwise see, which is traffic within your Layer 3-bounded network, meaning east-west traffic. It's hard to get that any other way."
"The gradual way the Network Insight shows you all the relevant information about your networks. It's pretty good. You can really dig deep deep inside and see where the problem is, where it comes from, what you have inside, how did you configure it. Also, it has alerts so you can have pretty much quite a big overview about your network. This is really something good."
"If we deploy NSX it shows us how the workflow will flow in the organization, what the roadblocks are, and what we need to do to overcome those hurdles. When we run this product, it gives us reports which describe problems with physical switches. We work with the network team to get them all resolved."
"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."
"Also, the ability to troubleshoot all the way across the NSX part of it to the physical and actually watch the packets go through and then see where the bottleneck is or where the interruption is. We run queries on the network flows within the application to find where they are in it and it graphically tells us how the packets are actually going through the system."
"It has definitely helped us to meet compliance rules by assuring that all traffic is going to where it's supposed to go. It can be used to report that you are in compliance, as well as helping you get into compliance."
"We haven't had any complaints about the stability of the solution or heard of any issues. None of our clients have mentioned running into bugs or glitches. There haven't been crashes."
"As a troubleshooting tool, it's a level-3 troubleshooting-skills tool and it's very easy to use and very easy to find the information that you need."
 

Cons

"One of the drawbacks of the standard Nmap utility is that it does not come with a graphical user interface, unlike a number of other open-source alternatives such as Zenmap."
"The solution's initial setup could be better."
"The price is high and could be cheaper."
"They should deliver Playtech's username and password."
"Nmap needs to improve its scanning speed."
"Customization is not very user-friendly in Nmap."
"The tool's license limits the number of scans it can perform. Improving the license model could benefit customers by allowing more scans for compliance and other purposes."
"There could be a specific option to check non-pingable endpoints for the product."
"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."
"After Broadcom acquired VMware, I would rate their support at five or less in many cases. It's difficult to find necessary documentation, open tickets, and get support."
"I want to see more in terms of microsegmentation. As of now, I can see the rules, but they are not in a readable format that I can convert to microsegmentation and can fit into NSX Manager."
"The only issue we have is that the solution does not always capture the host names."
"There is room for improvement when it comes to pricing because we pay here in Brazil, and all the costs are based on the dollar."
"I would like to see more reporting features, more dashboards."
"There's enough information there, especially in the visualizations, but I would love to see this in a kiosk mode, where I could have a dashboard for interested stakeholders to see and appreciate what's going on. Then, moving on to a more practical level for our Help Desk, our operations team could benefit by seeing, in real-time, a visual view of the network."
"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."
 

Pricing and Cost Advice

"The solution is free of cost."
"I am using the free version of Nmap."
"The solution is free of cost, but there are specific services that we have to buy."
"The product's pricing is fine. The licensing options for Nmap include perpetual licenses and volume-based licenses. For perpetual licenses, once you purchase it, there's no need to invest in renewals. And for volume-based licenses, enterprise companies can use it multiple times based on the number of users or devices they need to scan. It's a pay-as-you-go model, similar to how you pay for what you use."
"Nmap is an open-source and free product."
"I am using the standard free version of Nmap."
"It's an open-source product, and I haven't seen any premiums. Options are available for those who purchase, but for my use case, everything I need is available in the community and forums."
"It's an open-source solution. Commerically, only the support service is available."
"It's an expensive product because we have a lot of nodes."
"They should include the product in NSX because it's important to have it for deployment."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"It has brought more money into our company."
"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."
"We have spent less time investigating network flows, so it is absolutely cost-effective."
"vRealize Network Insight is expensive."
"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."
