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

"The solution detects the operating systems, which makes testing the software much easier before making the payload."

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

"It is a very user-friendly product."

"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."

"It helps us secure the network infrastructure."

"The most important function, according to me, is the capability to use some arguments in the scanning. The solution's capability to go figure and do a deep dive, discovering information on specific aspects."

"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."

More Nmap pros

"It is user-friendly. It's pretty simple to deploy and to run. It gives you pretty easy-to-understand reports, very graphically intense, so you can visualize what's going on in your network."

"The best feature of this application is its ability to capture everything within the same application, as well as capture all the traffic."

"compare-to-competition; I would recommend the product. I don't think there is any other product like this on the market right now."

"It allowed us to set up NSX and to do microsegmentation, without all of the pain points of having to determine each port and each IP address that needed to have access, and which ones needed to be blocked."

"It's a very powerful, very manageable product."

"One of the most valuable features is the ability to look at the traffic flows, to look at NetFlow data."

"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."

"The solution helps reduce time to value, increase performance, provide deep visibility, and easily manage networks."

More vRealize Network Insight pros

Cons

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

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

"They should deliver Playtech's username and password."

"There are concerns with the stability of the product, making it an area where improvements are required."

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

"There could be a specific option to check non-pingable endpoints for the product."

"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."

More Nmap cons

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

"The virtual appliance has rebooted."

"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."

"Support could be much better."

"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."

"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 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."

"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."

Pricing and Cost Advice

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

"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."

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

"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 product. You don't need a license to install it."

"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."

More Nmap pricing and cost advice

"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."

"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."

"It has brought more money into our company."

"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."

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).

Nmap

VMware vRealize Network Insight delivers intelligent operations for software-defined networking and security. It helps customers build an optimized, highly-available and secure network infrastructure across multi-cloud environments. It accelerates micro-segmentation planning and deployment, enables visibility across virtual and physical networks and provides operational views to manage and scale VMware NSX deployments.
