NETSCOUT nGeniusONE vs. Nmap

It’s best for troubleshooting issues that require a packet level analysis. By having source/destination you can have a view into how the packets are traversing the network. If alerts/baselines are set up it can help identify something out of the norm. Very useful for VoIP applications as well. Would not recommend for small scale environments.

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.

• The graphical interface has to be the key benefit of NetScout. I am more of a packet analyzer but the interface gives the upper levels easier view into the network.
• The breakdown of sites is useful.
• The ability of the break the traffic down and go into the packet analyzer straight from the graphical interface. Saves a lot of time writing filters with just simple clicks.

• 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.

• Better access to resources
• Pricing in this niche market is very high, hard for the little guy to take advantage of these solutions

• 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.

It provides a lot of useful information, but it's not always easy/intuitive to find it. It really needs to get a fully functional API integrated to support automation and integration with other monitoring and analytics tools to enable faster decision making. On the other hand, it gathers a lot of useful information from complex networks that are useful for capacity management and faster incident isolation and resolution.

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.

We have a dedicated OSE who has been very helpful. Besides that, we have little experience beyond this specific model

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.

NETSCOUT nGeniusONE is the best solution which we have encountered so far. The best part about this is that it can be integrated with various third party tool for more visibility and behavior analysis. The dashboard is loaded with a lot of useful features which gives the complete trend analysis of connectivity loss and network flaps and helps to identify the critical sites which is not present in other technology solution. This is an incredible network performance monitoring tool

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'.

• NetScout nGeniusONE helps to reduce the time and effort (people to involve) to react on network outages, speed up the investigation progress, and much more quickly to identify the root cause.
• Proactive helps the operation team to identify the underline problems and help the business to take actions before the issue starts to impact the customer's business. Help to reduce the incidents and outages.
• Help the operation teams to better understand the performance and health of the network from a higher level and end to end perspective, improve the efficiency of work.

• 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.
