Shows question being asked, breaks it down and it'll just show you who's not answering

I wouldn't want the interface to go towards the web because they did have a version that was inside of the TruView product. It was more web-based and, to me, the web-based applications lose the robustness of the intimacy of a true character interface. I liked that they were on that path and I hope that they stay on that path because it just looks like it's a better product. I would like to see a multi-user version where you can have a launch platform and, potentially, instead of buying six licenses you buy 12 seats or something like that. From a centralized platform, you could have multiple users using that particular product in a series of different ways. That's what I'd like to see, rather than having everybody running a standalone one on their own workstation.

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

"What ClearSight will do is it actually maps out the conversation for you."

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

"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 has a powerful command line tool and a set of diagnostic features."

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

"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."

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

"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."

Cons

"I would like to see a multi-user version where you can have a launch platform and, potentially, instead of buying six licenses you buy 12 seats or something like that."

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

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

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

"Nmap needs to improve its scanning speed."

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

"Customization is not very user-friendly in Nmap."

"The price is high and could be cheaper."

"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."

Pricing and Cost Advice

"It was pretty modest because you could get it in different ways. I think the six licenses, at that time, were about $1,000 each. But then again, I work for a school and educators tend to get discounts on things. So maybe it cost us about five or six hundred a copy."

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

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

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

"I am using the free version of Nmap."

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

"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."

"The solution is free of cost."

Overview

Protocol analysis tool for application performance analysis and monitoring. Provides real-time problem identification and statistics.

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).
