Overall Satisfaction with Nmap

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.
  • Finding security holes in VM and network client config, leading to patching.
  • Finding rogue devices not approved by IT, helping prevent security incidents.
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.
