Nmap vs. Preseem

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.

For any ISP that wants to know the QoE their customers experience while using their service, Preseem is an excellent choice. The rate plan shaping also makes sure the connection feels fast, even if the speeds are being 100% utilized by the customer. This is not a DPI service though, so you can't classify or shape certain services over others. All traffic is treated fairly, and small flows are moved to the front of the queue to make sure interactive traffic like VOIP, DNS, and gaming is working well ahead of large downloads.

• 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.

• The tool could stand to be a little less engineered, but really the ROI isn't there for them to do so. I don't think most of us care about how pretty it looks, more so does it work and can I figure it out in relatively short order.

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.

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.

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'.

Any Amplifi product can show client infrastructure usage and date. the Dream Machine is perfect because it has built-in everything for the client to manage his local network.

• NMap being free of charge has a positive impact on our budget. It is an enterprise-class tool that anyone can download and use.
• NMap, both command line and GUI, is a very advanced tool that is easy to use, so there's very little learning curve involved, which has a positive impact on productivity and security.
• A valuable feature that is a huge time saver is that you can compare scans. This saves hours of searching manually for differences in scan results. Faster results means faster mitigation of problems, which can be a real money saver.
