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.

Helps us by providing root cause analysis when it comes to latency and performance issues

I would recommend NETSCOUT nGeniusONE to others yet not for small SMBs due to the pricing. It is important to have the necessary NETSCOUT experience for smooth integration. The automated issue detection sometimes has a few false positives but is overall cost-effective for our customers. I'd rate the solution eight out of ten.

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.

Quotes from Members

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

Pros

"The most valuable feature is visibility."

"The most valuable feature of NETSCOUT nGeniusONE is it helps customer to understand what risks are in their network. For example, if a customer has some wrong configurations. It could cost them some critical services to slow down."

"From the standpoint of VoLTE and related things, it's providing visibility into the network and how it operates."

"Deep packet inspection is a very useful tool as it works in real time and uses serial packet-level analysis."

"This solution provides us with increased visibility while conducting IT deployments. E.g., 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. Very few tools do it at this level for things like DDoS."

"When we have any type of outage, and we dig into it, we are able to tell what the root cause is instead of having to go through Wireshark, etc."

"The solution helps to troubleshoot and put our hands on the weak points of customer networks."

"The packet capture is the most valuable feature for us. It gathers data from the device. In case somebody has a problem, I can go back X amount of time - days, hours - and get the data to do real troubleshooting."

More NETSCOUT nGeniusONE pros

"It helps us secure the network infrastructure."

"The scanning procedure includes UDP ports which sets it apart from competitors."

"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 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 initial setup was simple."

"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."

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

More Nmap pros

Cons

"The current solution is not easy to scale, because it is an appliance-based solution. So, you have to swap everything out."

"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."

"I'd like to see the nGeniusONE, the nGeniusPULSE, and the OptiView, their three separate products, work a little better together, a little more streamlined."

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

"NETSCOUT nGeniusONE is a complex product since it deals in areas like network packet brokers and packet analysis, making the tool complicated for end users."

"The product was lacking for awhile when they did the Arbor acquisition. I was waiting to see more security stuff, which they did eventually add, and is now impressive."

"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."

"We would like more encryption of customer data, because we have a very security conscious company. We have a lot of regulation coming in which requires us to make customer data private."

More NETSCOUT nGeniusONE cons

"The price is high and could be cheaper."

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

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

"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."

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

"Nmap needs to improve its scanning speed."

"There is room for improvement in the design, the GUI. It looks a bit odd. Maybe Nmap should improve it or add more widgets to make it more attractive, but the basic functionality is good and provides what we need."

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

More Nmap cons

Pricing and Cost Advice

"It is very expensive, but it's well worth the money."

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

"The platform is expensive."

"There is a need to make yearly payments towards the licensing charges attached to the product. The product may come across as a cheap tool for some, while it may seem costly for others."

"The biggest problem we have with this product is the expense."

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

"The license becomes cost prohibitive very quickly."

"The product is too expensive compared to other products."

More NETSCOUT nGeniusONE pricing and cost advice

"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."

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

"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."

"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."

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

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

"The solution is free of cost, but there are specific services that we have to buy."

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).
