Executive SummaryUpdated on Oct 10, 2024

NETSCOUT nGeniusONE and Nmap both compete in the network analysis category, addressing different needs. While nGeniusONE dominates with its feature-rich offerings for deep network visibility, Nmap holds its ground due to cost-effectiveness, making it favorable for budget-conscious users.

Features: NETSCOUT nGeniusONE provides in-depth network traffic analysis, packet inspection, and application-specific monitoring. It offers tools for troubleshooting network issues like jitter and latency, alongside a comprehensive dashboard for real-time communication monitoring. Nmap is efficient in network scanning and port detection, excels in OS identification, and offers advanced script scanning for vulnerability detection.

Room for Improvement: NETSCOUT nGeniusONE users suggest a more user-friendly interface and a modular pricing strategy to avoid paying for unused features. Improvements are also needed in dependency mapping and tool integration. Nmap users advocate for a graphical interface to attract less technical users, faster scanning speeds, and enhanced service identification capabilities.

Ease of Deployment and Customer Service: NETSCOUT nGeniusONE is typically deployed on-premises with hybrid and private cloud options, requiring dedicated support due to complexity. Nmap, primarily on-premises with some hybrid capabilities, benefits from its open-source nature, reducing the need for extensive support, though improved guidance could assist new users.

Pricing and ROI: NETSCOUT nGeniusONE is expensive, with users questioning ROI against budget options, despite its comprehensive monitoring. Nmap, being free and open-source, supports tight budgets while delivering essential network security features without a significant financial investment.

Offers detailed network monitoring but requires improvement in deployment complexity and pricing

The price is really high, making it difficult for many financial companies to purchase immediately; it will take time for them to afford any budget for the purchase. The traffic data correlation feature's effectiveness with performance issues for clients remains uncertain as there are questions that need to be addressed through engineers regarding how many customers are actually using it. Regarding pricing and value for money, while the solution has the potential to save time and money for clients in the long term, monitoring solutions for performance management or network monitoring do not cause immediate damage to a company. It could lead to damage over time, but financial and management teams typically cannot see the immediate crisis. This is why many big companies Samsung and Hyundai try to build their own monitoring solutions using open-source tools and their own engineers, though it has not been successful.

Penetration testing has become efficient as I identify open ports and security risks with confidence

Nmap could potentially become a GUI and provide automatic reports with one-click downloads. For example, the report could show all the open ports for an IP address with a professionally formatted report. This is a far-fetched suggestion and not really required, but it could make the work a little better. On a scale of one to ten, I give Nmap a solid nine. I mean, how can you fix something that is not broken? Nmap is already the best, and I do not think there are any other features that can be added. Its job is reconnaissance, so I do not think there is more to add to it. However, if I get any ideas, I will let them know about this.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It is an easy-to-scale platform."

"The solution transforms packet wire data into real-time data that is ready to act on."

"It's easy to detect unwanted traffic with all the detection tools available."

"The solution helps us get to root cause quickly by using the Media Monitor to help identify QoS mismatches for voice calls on the network."

"This solution provides us with increased visibility while conducting IT deployments, for example, if we have devices which have overloaded or links which have saturated, then this tool tells us exactly what is going on with that link or device, and very few tools do it at this level for things like DDoS."

"From my user community, I am getting the impression that something which used to take days has now gone to hours for troubleshooting."

"It has helped with the operations teams, who have been able to collect information and troubleshoot with the application."

"It is a scalable solution."

More NETSCOUT nGeniusONE pros

"The solution really is not comparable to other products because of its many features."

"This was my first project, and Nmap was the best tool that I have used to date, and I recommend it to everyone."

"It helps us secure the network infrastructure."

"The initial setup was simple."

"Nmap is easy to use. It's a command-line interface, and the output is quite good."

"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."

"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."

"It’s an excellent tool and allows its users a multitude of solutions to scan a network."

More Nmap pros

Cons

"The solution could do more for security. It should offer more security-related features."

"I think it could have an easier to understand interface."

"The dependency mapping is good, but I am hopeful that they will build some type of partnership and relationship with ServiceNow. I want to see NETSCOUT partner with ServiceNow so they can leverage Service Now Discovery and Service Mapping to automate the build of the service dependency mappings inside of nGeniusONE."

"Initially, we were having a lot of issues with bugs when using version 6.1.1. There were a lot of problems with the dashboard causing confusion. We worked with our SE and the NETSCOUT engineering team to fix the visibility with the data. There should be a patch release to fix this issue. However, this seems to be working fine for us right now after the 6.2.2 upgrade."

"The product is a little complicated."

"NG1 has been stable for a while in our environment - at least we have what we needed. But with nBA, there's a lot of room for improvement."

"The initial deployment is tedious and requires a lot of build, deployment and configuration time. Experience is key to a successful deployment."

"When we would like to use a feature, we have to remove another one. For me it's a bit of a drawback; I'm a bit frustrated with it."

More NETSCOUT nGeniusONE cons

"Nmap will be a little difficult for beginners because of the learning curve and the CLI-based system, but once you get the hang of it, it becomes very powerful."

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

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

"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's initial setup could be better."

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

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

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

Pricing and Cost Advice

"It can be expensive, but if you have a good configuration, based on what you are looking for, it's okay, it's manageable."

"If you are able and you are willing to use everything that Netscout provides to you, it's probably a relatively fair price. The problem is that it's such a large and such a complex tool that I'm not sure that many companies would be able to use it entirely, the way it's expected to be used."

"The price is only for acquisition; it's not a licence."

"Cost is probably the biggest drawback. Compared to some of the newer vendors that have popped up in the space, it's definitely more on the expensive side... [But] it's been able to keep its value, even in the face of the cheaper competition."

"We have a premium customized contract for the solution."

"The license becomes cost prohibitive very quickly."

"Licensing is flexible, it's not tied to anything else. We can easily switch up the licensing piece... Obviously, NETSCOUT is a little bit in the higher range, but it gives you value for money. You get what you pay for."

"This solution has saved us more than $50,000 a month and freed up 30 percent of our bandwidth."

More NETSCOUT nGeniusONE pricing and cost advice

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

"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."

"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."

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

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

"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."

Overview

The nGenius Real-Time Monitor software provides you with tools to monitor and display information about your network both historically and in real time. The nGenius Real-Time Monitor software allows you to understand your current network usage and to plan for future needs. It also allows you to proactively troubleshoot problem areas in your network.

NETSCOUT

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).
