"GUI front-end that brings Nmap’s power to the desktop"
4.5/5
What do you like best about Zenmap?

Zenmap serves as the official graphical interface for Nmap, exposing all command-line functionality through an intuitive desktop application. The cross-platform compatibility ensures consistent deployment across Windows, Linux, and macOS environments.

Profile management streamlines recurring scans by storing configurations as reusable templates. The Command Creator pane provides real-time CLI translation, making it an effective learning tool for transitioning from GUI to command-line workflows.

Output persistence handles multiple formats (XML, grepable, SQLite) automatically, enabling historical analysis and third-party integration. The Diff function highlights changes between scan results through color-coded comparisons, accelerating change control processes.

The Topology tab renders network relationships as visual graphs, providing immediate insight into network segmentation without parsing raw traceroute data. Full NSE script integration allows vulnerability assessment directly through the interface. Review collected by and hosted on G2.com.

What do you dislike about Zenmap?

The application depends on deprecated Python 2 and GTK2 libraries, creating compatibility issues on modern systems. Release cycles lag behind the core Nmap engine, leaving newer features unavailable through the GUI.

Performance degrades significantly with large result sets - the topology view becomes unresponsive beyond 2,000 hosts. Administrative privileges are required for advanced scan techniques with no graceful fallback options.

The lack of automation endpoints prevents integration with CI/CD pipelines, forcing manual workflows for routine operations. Review collected by and hosted on G2.com.

"A quick review of Zenmap"
4/5
What do you like best about Zenmap?

Zenmap is the best tool for penetration testers, ethical hackers, and cyber security analysts. It's used for showing services on web servers, open ports, and versions on web servers. It is easy to use and ease of implementation. Review collected by and hosted on G2.com.

What do you dislike about Zenmap?

Yes, that is a very limited command to use. And in Kali Linux, I'm using a lot of commands. So I think that is some issue of Zenmap. Also, Zenmap's UI is not good but I don't think integration is possible or not with Zenmap. Review collected by and hosted on G2.com.

"Using this tool has made it easy to scan a network and gain information like ports and services."
4/5
What do you like best about Zenmap?

It is easy to use and convenient, and gives much information by using different plugins. Review collected by and hosted on G2.com.

What do you dislike about Zenmap?

The result is not saved anywhere, if it automatically saves the result somewhere it would be easy. As I have mistakenly ended many running scans. Review collected by and hosted on G2.com.

"Excellent tool for network security"
5/5
What do you like best about Zenmap?

Zenmap is a relatively simple tool to use; select your target and the scans you want to perform against it. I can scan for open ports and see which services are running on them. I can also check for malware using scripts from the NSE. Its vulnerability scanning is excellent in identifying vulnerable systems for patching. With Zenmap, you can scan for vulnerabilities, see where they are within your network or devices, and begin patching them. I like that I can scan different or specific systems without having to sit directly in front of them which to me is one of the best things about Zenmap. Review collected by and hosted on G2.com.

What do you dislike about Zenmap?

The scan result can be a little difficult to read and understand. Also, it would be nice if Zenmap could download the updates or patches needed for the vulnerabilities found and install them. Review collected by and hosted on G2.com.

"Scanning a network can be simple"
5/5
What do you like best about Zenmap?

Easy to use, you can get a lot of information from the scans and there's a big community ready to help with the commands if required. Review collected by and hosted on G2.com.

What do you dislike about Zenmap?

It's hard to understand at the beginning. Sometimes it takes a lot of time to give you simple scans and sometimes it does bring you all the information Review collected by and hosted on G2.com.

"Multi-functional IP Scanner"
4/5
What do you like best about Zenmap?

First of all, it's completely free because it is tough to find a free IP scanner for the m1 chip MacBook pro. That's why I love it. Also, it has many features, and results are coming clear and with different styles. Review collected by and hosted on G2.com.

What do you dislike about Zenmap?

Unfortunately, user interface is blurred and not optimized for the M1 MacBook Pro. Sometimes program getting, too. Review collected by and hosted on G2.com.

"Zenmap - The Ultimate NMAP GUI"
5/5
What do you like best about Zenmap?

The GUI covers everything you need to analyse your entire local area network. It also helps visualize the topology and clearly shows all sophisticated and verbose findings for hosts and devices in the network. Review collected by and hosted on G2.com.

What do you dislike about Zenmap?

The GUI can get pretty non-responsive and the included NPCAP compatibility adapter can interrupt your internet supply due to conflicting metrics but that can be fixed manually. Review collected by and hosted on G2.com.

"Zenmap Tool for Network Discovery"
4.5/5
What do you like best about Zenmap?

The ease of use and power of this network scanner. Learning to use the tool in a cursory manner is relatively easy, which makes getting started with it extremely simple and straightforward. Review collected by and hosted on G2.com.

What do you dislike about Zenmap?

There is a bit of a learning curve to go from novice to power user. Once you want to delve deeper into what can be done with this tool, it takes quite a bit of further understanding - not as simple and easy as starting off. Review collected by and hosted on G2.com.
