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

"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 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 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 enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."

"It helps us secure the network infrastructure."

"From a functionality standpoint, it's robust and straightforward to comprehend."

"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."

More Nmap pros

"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."

"The most valuable features are the monitoring and tracking. It's also intuitive and user-friendly. The screen looks exactly the same as the other appliances for VMware, so it's easy to navigate."

"The graphical interface of this environment is so good with all the views, the graphics, and everything in them. It's really easy for me. It doesn't need an engineer to work on it. It's easy enough that anyone can get into the environment and look for issues or look at how communication is going on across the VMs. It's pretty much straightforward."

"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 gives the visibility that was either broken or there in pieces only. This solution provides a unified view of the whole system, back and forth. It has helped to reduce time to value, increase performance, more easily manage networks, and provide deep visibility."

"The most valuable feture is NetFlow to help us understand how VMs communicate with each other over ports that are known and ports that are also unknown to us. Our company is a security company, so it's very important for us to know exactly which VMs are doing what at all times."

"It provides deep visibility into what is happening with traffic and helps us manage our network."

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

More vRealize Network Insight pros

Cons

"The challenge often lies in finding suitable courses and professional resources."

"The price is high and could be cheaper."

"The solution's initial setup could be better."

"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."

"The solution is not that easy for a beginner to learn."

"The solution should increase the number of features under a free license."

"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."

"It takes a bit of time to get familiar with the solution and its options."

More Nmap cons

"When we talk about those micro-segmentation rules, there's an Export function. It is very macro-segmentation oriented instead. So if you choose an application, it will find the tiers within that application and say that it's communicating on, say, port 80 to a separate VLAN. There might be 200 machines in that other VLAN. You don't want to open port 80 at all of them. So we need a lot more granularity in those suggested firewall rules."

"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."

"If it were more application-aware, more descriptive; if it were able to determine the application that is actually doing the communication, that would be easier. More application information: which user or account it's accessing, is it accessing this application, doing these calls, if it is accessing a script, what script is it accessing. Things like that would provide deeper analytics so I can track what's going on. It would not just be, "These people shouldn't be talking," but who is actually doing these calls."

"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 interoperability on the firewall and low balancer sides."

"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."

"Since Broadcom acquired VMware, it has been experiencing challenges. Many sales processes are not well defined."

"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."

Pricing and Cost Advice

"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."

"The solution is free of cost."

"Nmap is an open-source and free product."

"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 an open-source product. You don't need a license to install it."

"It's an open-source solution. Commerically, only the support service is available."

"I am using the standard free version of Nmap."

"The solution is open source so it is free."

More Nmap pricing and cost advice

"It has brought more money into our company."

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

"vRealize Network Insight is expensive."

"It's an expensive product because we have a lot of nodes."

"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."

"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 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."

Overview

Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).
