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

"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."
"The solution detects the operating systems, which makes testing the software much easier before making the payload."
"It is a very user-friendly product."
"Nmap has a powerful command line tool and a set of diagnostic features."
"From a functionality standpoint, it's robust and straightforward to comprehend."
"The tool's most valuable feature is its scripts. These scripts prove beneficial when security features may obscure or block connections. Nmap helps identify vulnerabilities across different systems, including web servers and various server types."
"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 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 ability to use the natural language query and see the visualization is quickly intuitive, and it works very well."
"It's a very powerful, very manageable product."
"With this product, we can precisely identify communication patterns between virtual machines within our data center, whether it's east-east or east-west communication."
"By doing dependency mapping, it makes migrations more efficient. There are less outages that require engineers to spend additional hours troubleshooting the migration failures."
"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."
"It especially helps with deploying NSX, that you're not having to manually chase down and figure out what you need to do to microsegment VMs. This gives a nice option where you can say, "Hey, this VM, show me what flows are there." I can export it out and then import it as an NSX rule and job done."
"The best feature of this application is its ability to capture everything within the same application, as well as capture all the traffic."
 

Cons

"The challenge often lies in finding suitable courses and professional resources."
"Nmap needs to improve its scanning speed."
"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."
"Since I started using Nmap, it has been completely based on the command prompt and I think it would help other users if they implemented a decent GUI as well."
"The price is high and could be cheaper."
"There could be a specific option to check non-pingable endpoints for the product."
"The solution should increase the number of features under a free license."
"The solution's initial setup could be better."
"I want to be able to monitor a network flow that is approximately two weeks back, but I haven't found an easy way to do this."
"The IT infrastructure industry is expected to evolve towards a hybrid cloud model in the next five to ten years. In this model, most of the customer's resources reside on-premise within a private cloud setup, such as VMware. Another segment operates within public cloud environments like Azure and AWS, and a portion remains in traditional data centers. There should be seamless interoperability between public and private clouds. AWS and VMware need to work together to make it possible. Whether users interact with on-premise infrastructure or configure resources in the public cloud, the user experience must be seamless."
"Support could be much better."
"vRNI needs more remediation where it hooks into NSX."
"The only reason I would not give it a nine or a 10 is for cost reasons. It seems to be one of those things that really belongs as part of the product inherently and not as an add-on. That would be my only concern."
"It needs to be a little easier to use and to understand the information it's putting out. That would make it more helpful. If you're not a network person you need to understand things like network policies and concepts. If you gave it to a regular admin, it would be nice if it were easier for them to pick up what is going on, understand the flows and whether or not stuff should be talking to each other, as opposed to just port groups and IP addresses."
"The solution is very much viewer centric and it would be nice if it would transcend just the virtual infrastructure."
"While it's not exactly a feature, what normally happens when we are trying to look at the VM flow portion is - although Network Insight does have options to integrate a few physical switches into it - we can't really get an end-to-end flow of the network. We might be using a few switches that are not supported by Network Insight. That is where they can improve, in the support for more physical switches and network devices."
 

Pricing and Cost Advice

"The solution is free of cost."
"The solution is free of cost, but there are specific services that we have to buy."
"It's an open-source solution. Commerically, only the support service is available."
"The solution is open source so it is free."
"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."
"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."
"I am using the standard free version of Nmap."
"I am using the free version of Nmap."
"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."
"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."
"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."
"It has brought more money into our company."
"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."
"I rate vRealize Network Insight's pricing a seven point five out of ten."
