Scans the network and identifies vulnerabilities on each machine
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 tool's most valuable feature is its vulnerability scanning. It allows us to scan a specific range of IP addresses and discover devices within that range. This makes it easy to identify devices and view their details. Port scanning is crucial for network management tasks. It helps us identify vulnerabilities by finding open ports that may be unused or misconfigured. This tool makes it easy to detect such issues. The OS detection feature is great. Unlike other tools, Nmap provides accurate information about asset vulnerabilities, helping us easily detect and address them. Using Nmap provides value to the company, especially during compliance audits. It helps generate reports on assets, updates on workstations, and insights into network activities and potential attacks. Additionally, Nmap detects vulnerabilities and provides port details, allowing us to close unused ports on the client machines.

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

"Nmap has a powerful command line tool and a set of diagnostic features."
"The most valuable feature of the solution for security audits stems from the fact that it serves as a powerful tool with the ability to scan a large number of ports."
"It helps us secure the network infrastructure."
"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 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."
"It is a very user-friendly product."
"The scanning procedure includes UDP ports which sets it apart from competitors."
"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."
"It allows us to see how the network devices function as well as to see network glitches or fluctuations or dropping of packets."
"We're a smaller company so it automates a lot of the tasks and lets us focus in on building out our own solution. It's quicker, there is less building of manual solutions, and less downtime. It allows our developers to quickly develop, get provisioning done, de-provisioning, etc; the stuff that you would expect to be able to make it streamlined."
"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."
"A lot of time is saved when you use this type of software solution for the network. We have moved systems into the new data center and the servers and systems are much faster because of the very low latency between virtual machines."
"I find it user-friendly and intuitive. With the GUI interface that we do use on a regular basis, it's easy to navigate, it's easy to see, easy to query. We get reports. It's easy to use."
"The initial setup was straightforward."
"The most valuable feature for us is that insight into what our network is really doing - it's a fairly complex network. Not having to go through thousands of lines of network configuration to find firewall ports that were open or closed, for various ports, was very valuable. It went out and found everything we need very quickly."
"The solution helps reduce time to value, increase performance, provide deep visibility, and easily manage networks."
 

Cons

"It takes a bit of time to get familiar with the solution and its options."
"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."
"Customization is not very user-friendly in Nmap."
"There are concerns with the stability of the product, making it an area where improvements are required."
"The challenge often lies in finding suitable courses and professional resources."
"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."
"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."
"The solution's initial setup could be better."
"The virtual appliance has rebooted."
"The product is slightly complex use, while still being user-friendly. It could use more training modules, as it is not a straightforward product."
"The only issue we have is that the solution does not always capture the host names."
"The solution can be improved by making it more compatible with other brands, allowing for better integration."
"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."
"I would like to see more interoperability on the firewall and low balancer sides."
"The only real improvement they can make is to add more third-party vendors into the environment, mostly switch manufacturers, because it's really limited to Cisco equipment and there are a lot of companies out there other than Cisco."
"After you use it for a little while you become accustomed to it but the layout doesn't feel very intuitive. You have to dig around and find the exact place where you can find the information, where you can actually see your east-west traffic, etc. I would like them to bring that information more to the forefront, instead of having to find it."
 

Pricing and Cost Advice

"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."
"The solution is free of cost."
"The solution is free of cost, but there are specific services that we have to buy."
"The solution is open source so it is free."
"Nmap is an open-source product. You don't need a license to install it."
"I am using the free version of Nmap."
"Nmap is an open-source and free product."
"Nmap is open source software, which suits us well because we are a manufacturing company and not an IT company, for example. If we were an IT company, we would probably need to pay for extra support or instead go for another software solution. But as it is, we don't have any need for high-end troubleshooting tools."
"We have spent less time investigating network flows, so it is absolutely cost-effective."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
"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."
"It's an expensive product because we have a lot of nodes."
"vRealize Network Insight is expensive."
"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."
"They should include the product in NSX because it's important to have it for deployment."
"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."
