Zenmap is basically Nmap with a user interface, and that's what I really like about zenmap, because zenmap let us scan networks without having to enter most of commands, because zenmap will give us lists of commands that we can select from, with zenmap, we can see the network structure and connected computers in a network topology, which I found really helpful.

It's a GUI version of Nmap but, in Zenmap we still have to enter commands to do most of the scans. There is no option to change the font style of the output, or color of the fonts, we won't even get any option to change into dark mode. Review collected by and hosted on G2.com.

One of the best tools to discover devices in your network. Zenmap can do everything that Nmap can do but with a nice user-friendly graphical user interface. With the help of Zenmap, it is really easy to get an understanding of your organization's network topology even if you are a new system admin. Review collected by and hosted on G2.com.

Operating System detection is not functioning very well, sometimes Zenmap displays wrong OS names. Review collected by and hosted on G2.com.

Zenmap is the GUI version of Nmap and I really like that, I can do lots of different scans on my network using Zenmap. It will show the open ports and services running on my network. I like that it shows the open ports in green colour in the result after scanning and that is very easy to spot and identify. After scanning I can see my hosts in Topology view which very easy to understand. Review collected by and hosted on G2.com.

Sometimes scanning takes more time than usual even when we use the same commands. They should have added more scanning profile option in the drop down menu. Review collected by and hosted on G2.com.

Zenmap is the graphical version of the Nmap security scanner. One of the best tools for port scanning and discover hosts and their services. It is available freely in many platforms such as Windows, Linux, Mac OS X. One of the great features is frequently using commands can be saved. Filters can be added easily. Zenmap provides a detailed output report about hosts and services. Review collected by and hosted on G2.com.

Sometimes scanning results are not 100% accurate. (Ex. OS version identifies differently.) Review collected by and hosted on G2.com.

nmap (The zenmap engine) is very powerful even from CLI but when combined with zenmap GUI it becomes more effective to quickly identify intruders with the real time topology view and other useful features such as stealth mode scan and quick scan plus traceroute to search for network hogs Review collected by and hosted on G2.com.

Some scan profiles are not documented and optimized so, they may cause slowness or decrease stability of your entire network or the hosts that you are scanning Review collected by and hosted on G2.com.

The main thing is the user interface is simple and straightforward. Also, it is the official GUI app for the Nmap. Different profiles can be set, and search results can be saved for later review. Different keyboard shortcut keys can be fixed. Review collected by and hosted on G2.com.

Sometimes Zenmap cannot identify precisely what operating systems are running. Review collected by and hosted on G2.com.

Its a legendary network scanner tool. Zenmap is actually the interactive interface for the nmap. It’s very simple and user friendly application which can be installed on operating systems like Windows, Linux, Mac OS. Using Zenmap, once we can specify the targets it provides us options to choose scan profiles which are already inbuilt into the application like quick scan, intense scan etc. The advantage of these profiles is that we don’t need to remember the commands to run the specific nmap scans, instead we can just select one of the profiles and just hit scan button to perform the scan. Once the scans are complete this application also provides options to see output of the scan, port and host information which shows the information about the open/closed ports of the target system along with the information about services, protocols regarding the open/closed ports, host details like MAC address of the system. Zenmap even provides options of profile editor which I think is one of the best features of this application. It actually allows to choose attributes to run the scan. It also has option to select from different categories of scripts to test particular vulnerabilities. Review collected by and hosted on G2.com.

I don’t have any complains about this application to be fair. Zenmap is really good and helpful tool although I have observed some false positive results about the ports information provided by Zenmap for targeted systems after completion of the scans during the past.

The interface is easy to get to work with and is with all command guides and can be very useful during assessments for scanning or running scripts, the support is great with community level connectivity. Review collected by and hosted on G2.com.

The interface could include topic-wise details, this may have been implemented in current updates, earlier it used to., the tool is very helpful overall. Review collected by and hosted on G2.com.

You can graphically export result without knowing CLI of nmap, the utility used by Zenmap to run scan over the network. OS detection is the best feature because you can accomplish information gathering and survey in a single scan and with a single tool Review collected by and hosted on G2.com.

No cons, maybe some scan profiles are not well documented and are a bit slower on zenmap than on nmap but I think this is caused by the gui Review collected by and hosted on G2.com.

It can draw "automatically" and without user interaction a full network topology with hosts status and "virtual" link between hosts, very useful to create network diagram and to see daily changes inside your network. Review collected by and hosted on G2.com.

No script library available, to make vulnerabilities assessments you have to download external script without security checks available. Review collected by and hosted on G2.com.
