Information

Use Cases and Deployment Scope

We use Nmap in our CyberSecurity department to detect different machines and software version in our clients' networks. It helps us to analyze easily the network topology of the network and detect misconfigurations or deprecated software. In that case, we can conduct remediations to patch the machines and improve security.

Pros

Ease of use
Completeness
Good interface
Lots of options

Cons

Curve of learning
Fluent design
Better docs

Likelihood to Recommend

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.

Use Cases and Deployment Scope

We use Nmap to do internal vulnerability testing and identifying holes in network security. The most common use case for me is to use Nmap to identify running services on devices to spot potential weaknesses in firewall rules or router rules. Many employees are familiar with Nmap and use it as well. It helps us identify problems quickly in new environments before we move to vulnerability scanning.

Pros

Nmap is great at finding live hosts on the network
Nmap is great for teaching new cyber specialist how network reconnaissance works
Nmap is built into every major recon tool on the market, it just works when it comes to scanning

Cons

There could be more built in tools for further vulnerability scanning
command line Nmap should store recent scans automatically
More detail in the help menu for what some of the triggers actually do

Likelihood to Recommend

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

Nmap

Use Cases and Deployment Scope

The software is used by me personally. Currently, I use Nmap to sweep LANs to determine if any rogue devices are connected. Additionally, any unknown items can be port scanned, and present services determined. Similarly, for security testing, vulnerabilities of specific VMs can be discovered using NSE scripts.

Pros

Scans for open ports, giving you the option of how aggressively or lightly to scan.
Can help determine which OS and services are running on a device, again, giving the option of how aggressively to scan a device.

Cons

There is something of a learning curve in using the tool. A number of shortcuts and GUI options are available in Zenmap to simplify the process, but perhaps a more visual interface can help simplify the selection process prior to executing the Nmap command.

Likelihood to Recommend

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.
