What is Nmap?

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).

The product's port scan capabilities have positively impacted my company's network management tasks. The OS detection feature has benefited our company's network analysis since it shows me the open ports that are vulnerable. The product helps me get details about the vulnerability in open ports. I have not integrated the product with other tools except for the fact that I have used Nmap in Metasploit. I recommend the product to those who plan to use it for network security and management. The tool provides full scanning of ports. Though there are other products in the market, many of the solutions are not as good as Nmap, which offers a lot of features that are easy to use. I rate the solution a nine out of ten.

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.

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 had an OpenRx assessment module. So far, I can discover devices and gather information, but still, I may need other tools for vulnerability assessment. If they can add it to the stack, maybe it can be helpful.

"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."

Room for Improvement

Nmap users suggest improvements such as a graphical user interface to enhance usability and an increase in scanning speed. They desire features for better network insight and vulnerability assessment like those provided by competitor tools. Users seek a more accessible experience for beginners and additional API functionalities. Some suggest reduction in pricing, stability enhancements, and more licenses for extended scan capabilities. Overall, they propose community-driven updates and enhanced third-party library evaluations.

"The solution is not that easy for a beginner to learn."
"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."
"There are concerns with the stability of the product, making it an area where improvements are required."

Pricing

The pricing, setup cost, and licensing for Nmap vary depending on the version. There is a free version available, which is suitable for users who do not require advanced troubleshooting tools. However, for those who need additional support or more features, there are specific services that can be purchased, including a license for a professional version.

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