Intermapper vs. Nmap

If you've never mapped your network out before, download a demo of Intermapper and let it run. Your jaw will drop as your network grows before your eyes. If you have your network already mapped, you still would like InterMapper because it will find stuff you did not even know you have. If I were a network consultant, the first thing I would do when I hit a client's site is to start a scan with Intermapper. You will very quickly learn what the topography is.

Nmap is the ideal solution if you are working alot in network environments. If you come to grips with the syntax and the most-used features (the online community helps alot), you will be able to much more quickly and thoroughly troubleshoot networks or check for security vulnerabilities, for instance. It is free to use and is available for Windows and Linux, so I would say it is very much warrented for any network administrator or sysadmin to take it out for a spin.

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.

The product works well and is very easy to maintain. As such, we haven't had many occasions to use support. When we have called them they were easy to contact and responsive to our questions.

There is a very large support community and a robust selection of add-ons and scripts. Once you get the use down this is one of the most powerful tools and you can find anything you are looking for as far as examples on the web. While not having official support its not lacking by any means.

We have been using Intermapper for years and have been satisfied with it to the point that we haven't looked at competitors. The maintenance cost is very low and the product does exactly what we expect and need it to do. The product has gone through a couple owner transitions and still is a effective and when we first procured it.

A similar but more basic alternative is available on Android, called Fing. It's very useful for diagnosing issues on networks when you only have your mobile device to hand.

A graphical user interface alternative to Nmap, is Zenmap. It's the official GUI for Nmap and does use Nmap under the hood. It makes things a bit more 'point and click'.
