Overall Satisfaction with Nmap

NMap is used both by my department and other departments within our IT section. In particular, the network engineering department uses it to identify end-hosts that may be unauthorized to be on our network, while the security department uses it to assess the threats of different hosts within the enterprise network.
  • Highly accurate endpoint identification
  • Vulnerability scanning is detailed and clear.
  • Easily scripted and analyzed
  • CLI only; there is an unofficial graphical interface (but it isn't too great)
  • Not supported by a vendor
  • Somewhat steep learning curve
  • Increased Security (able to find and remove threats, obsolete devices, etc)
  • Improved knowledge of existing network devices
  • Improved mean-time-to-resolution of security incidents
  • BeyondTrust Network Security Scanner and powered by Retina
NMap usually lacks the features of the other network scanners, but for a good reason: most of the other network scanners out there are using NMap as part of their system. The nature of NMap (being open-source) is that it is available for use in other applications; as a result, these other applications make use of the NMap source code.
NMap doesn't really have support out there. There is fantastic documentation on it located at the NMap website, but no support to speak of. In this facet, another application may be a better fit for most organizations, at least if there is a support requirement to run the application. The good news is that Nmap doesn't cost money, so if it doesn't work for you and you can't find support, you'll be no worse off than when you started.

Do you think Nmap delivers good value for the price?


Are you happy with Nmap's feature set?


Did Nmap live up to sales and marketing promises?


Did implementation of Nmap go as expected?


Would you buy Nmap again?


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.
