If you're a sysadmin, or anyone who's had to deploy network services, you've almost certainly had to use Nmap at some point or other. Need to see what devices are on your LAN? Nmap can tell you that. Want to check which ports your web server has open to the internet? Nmap is your friend.

Nmap is a powerful command-line tool and has many options that require some reading of documentation to get the best out of (although generally straightforward). If the thought of working at the command-line scares you (presumably not if you're reading this review), then you may want a much simpler tool, or at least check out Zenmap GUI.

Nmap is the ideal solution if you are working alot in network environments. If you come to grips with the syntax and the most-used features (the online community helps alot), you will be able to much more quickly and thoroughly troubleshoot networks or check for security vulnerabilities, for instance. It is free to use and is available for Windows and Linux, so I would say it is very much warrented for any network administrator or sysadmin to take it out for a spin.

Often, when we get a new service or api or endpoint created, we like to check it out and verify network settings upon creation. Especially if there are ports open that we don't need or want depending on internal classification.
Also, when we set up a new product or do a proof-of-concept of a software we're looking into, we like to scan it and see what ports may be used and open and then bring it up with our sales engineers.

Nmap has helped us perform scans of our network to track down lost computers. In this virtual world it is easy to lose a physical box. Nmap has helped up find these lost machine and add appropriate monitoring tools on them. Nmap has also been crucial to find machines for Windows Operating system end of life project. Scanning machine and obtaining OS version is crucial for our Windows decom project.

Exporting the results from these scans do not always format nicely when imported into spreadsheet programs. much data manipulation is required.

Nmap is well suited to analyze a new network of which you don't have info, because you can find configurations, OS and software versions, and moreover. Nevertheless, I wouldn't use Nmap in certain environments, like OT, because you can interact with the processes. Besides, if you have a full knowledge of the nerwork, it won't be useful.

One of Nmaps strongest skills is the ability to gather initial evidence about networks to begin narrowing down target windows. Nmap can scan entire subnets and find only live hosts and then more intensively scan the live hosts to help identify which ones have the most vulnerable services or open ports. It is not suited for actual exploitation, just the initial steps

As a blue/red team member, NMAP is crucial to my day and I would highly recommend it to other users needing the same type of tool for scanning. This tool is a key program to use for enumeration and port-scanning a network. One of the caveats though is if you do not have network connectivity then this tool will not be able to provide any results.

Nmap is great at finding out the weak points within your internal and external network. Being able to find out exactly what devices are on your internal network is a great asset to securing your network from internal threats.

NMap is well suited to any environment that requires vulnerability scanning or endpoint identification. The application is free to use and well-documented. Any network that has technicians capable of running and interpreting scans would benefit from installing NMap. The only reason I wouldn't recommend NMap would be a scenario in which the users didn't have the capability to run or interpret the output of the application.

If you get an email saying your organization has failed its PCI scan because of a service running on a specific port that is a known port, say port 500 for a tunnel or something, and they want you to justify why port 500 is open, but you never opened port 500, you can use Nmap to check that. It's awesome in that role.

Is a powerful tool, but be careful not to make too many flood and SYN floods using this software. It can scan a lot of things and it can decrease performance on other device in the network.

As a new Network Admin coming into a network with virtually no documentation at the workstation OR server level, Nmap was the perfect starting point to get some idea of the types of devices on the network, the services they were running, and how they were configured at the port level.

I would say it excels in network sweeps for either inventory or footprinting. Very easy, intuitive, and the GUI does simplify the process considerably. I would say some of the more complex NSE scripts for finding holes in network security could be done a bit better, but for what it is, it is an excellent tool.

Nmap is well suited for already situated networks when looking for open IP addresses on the network. When a new piece of equipment, such as audio visual equipment, needs to have a static IP for support purposes, Nmap allows you to scan a full IP range and find an open one for you to use.

NMap is well suited to just about any situation, network size, or complexity. Some have brought up the point that NMap's proxy settings need work. I haven't used NMap with a proxy. NMap is my "go to" tool for a cursory security sweep. Once a problem is found, I can perform a deeper dive scan on a system or a network. I wouldn't, and don't, use NMap as my only security tool. No single tool has all the answers. For example, it is not a Wireshark in that it does not capture packets or analyze them. It is basically a port scanner, host discovery, OS detection tool.
