Overall Satisfaction with Nmap

We are generally using Nmap to scan our network segments for lost machines, open ports and vulnerabilities. There are several others that have used it but I am generally the only one to perform large scans.
  • Nmap is fast and flexible, It allows me to perform custom scan across my network(s)
  • Nmap provides crucial OS information when possible
  • comes in GUI and command-line versions
  • allows me to scan individual IP, ranges and full subnets
  • The ability to throttle the scan progress helps me to avoid triggering alarms
  • exporting, There's a serious lack of ability to export the information in a readable format to present to VPs and such. I always find myself doing a lot of data massaging to get it in a pretty format
  • some scans can trigger sensitive IDS/IPS
  • SYN scans can be particularly aggressive and cause problems on remote systems.
  • fast
  • flexible
  • customizable
  • Nmap is free. Its all profit baby!
  • Nmap has allowed up to be able to perform tasks for free which allows us to save $$ for other projects
I have used all three of these alternatives but they are generally limited in their function and ability to tweak settings. I have always found Nmap to be able to out perform these other products with ease.

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.
