Overall Satisfaction with Nmap

We use Nmap to help troubleshoot networking issues, run internal purple team events, and identify operating systems and open ports. During purple team events we use Nmap to run some exploits on systems to make sure they are not suspectable to the particular exploits. Externally, we perform scans to verify ports that are exposed to the internet. Sometimes we use it to see what systems are on a particular segment of our network.

Pros

  • Nmap is very good at discovering systems on your network.
  • Nmap is very good at guessing a systems operating system with a high degree of accuracy.
  • Nmap is good at validating externally facing systems to make sure that unauthorized access is not allowed.

Cons

  • The GUI version on Nmap could use some improvement with the options that are available to do scans. For example, they could make it easier to select options for the different types of scanning for people who are beginners
  • There are no abilities to schedule a scan in the Nmap tool.
  • An intensive scan sometimes takes too much time to complete.
  • Nmap is a part of other tools that I use and it give a high return on investment in the vulnerability management area.
  • It is very accurate with the information it provides. I would say more than 98% of the times Nmap is spot on the information it provides once validated.
Nmap uses are very practical and I don't think there is a better tools for what Nmap does. It is open-sources that therefore there is no cost to use it. It offers a number of benefits, including but not limited to network mapping, port scanning and more. It is very reliable as a network scanning tool.
Nmap out perform all other network mapping tools. Other tools will detect systems on a segment of network but does not always discover running services and open ports. In most cases Nmap scans out perform other tools with the speed at which it return it scan resuls. The price of Nmap is free therefore it is easy to acquire.

Do you think Nmap delivers good value for the price?

Yes

Are you happy with Nmap's feature set?

Yes

Did Nmap live up to sales and marketing promises?

Yes

Did implementation of Nmap go as expected?

Yes

Would you buy Nmap again?

Yes

Nmap is well suited for network discovery and finding open ports on systems. Nmap can also been used to discover some vulnerabilities or verify vulnerable systems. It is a good reconaissance tool for performing penetration test. The downside to Nmap I think is the ability to be stealthy for some scanning options. It can be a little bit noisy.
