Excellent tool for network security
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 anout Zenmap.
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.
Recommendations to others considering Zenmap?
Scan your network devices only. If you are using this professionally, ensure you have written permission to use the tool, clearly identify devices for scanning, and remember that ISP modems do not belong to the organization. Hence, don't scan them
What problems is Zenmap solving and how is that benefiting you?
A benefit to having Zenmap is that you can use it to uncover vulnerabilities within the environment. If you can reach a certain port you can see which service is occupying it and take the necessary action if needed. There is also the benefit of using more advanced features in the NSE for malware scanning, you can also write your own scripts with this feature and share with others.

Zenmap - The Ultimate NMAP GUI
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.
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.
Recommendations to others considering Zenmap?
Networking monitoring tools can be vast and expensive and hard to set up. So, if you're looking for an on-the-go solution for your company's network, without spending unnecessary resources, Zenmap might be the best choice for you.
What problems is Zenmap solving and how is that benefiting you?
I am a local IT Network admin and need to often verify the visibility of networking devices and hosts running in our private network. Zenmap is one of the most inexpensive and simple GUI tool for NMAP to diagnose all the layered changes that my team makes to the network visually.

Good and unexpensive network tool to have a clear vision of real-time network topology
What do you like best about Zenmap?
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.
What do you dislike about Zenmap?
No script library available, to make vulnerabilities assessments you have to download external script without security checks available.
What problems is Zenmap solving and how is that benefiting you?
Create and print four network diagram of four different subnets to use in Zabbix for real time host monitoring map features.
