What is Nmap?UNIXBusinessApplication
Price:

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.

I use Nmap just for vulnerability assessment, especially for network discovery. I can scan a network and get total information about the device, the operating system, IP, and all of the services running. So, Nmap is one of the good tools The most important function, according to me, is the…

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. A second drawback is that the network scanning process can be very slow. I believe that the developers should improve the scanning speed, or perhaps offer an extra option for quicker scanning. Lastly, even though I can scan the network, the utility doesn't provide any way to fix the network issues that may be discovered. That said, I understand that the tool is not intended for fixing anything, but rather for monitoring and discovery only.

Key learnings from peers

Last updated Apr 23, 2024

Valuable Features

"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 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."
"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."

Room for Improvement

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

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.

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