Nmap vs. SolarWinds NetFlow Traffic Analyzer (NTA)

If you're a sysadmin, or anyone who's had to deploy network services, you've almost certainly had to use Nmap at some point or other. Need to see what devices are on your LAN? Nmap can tell you that. Want to check which ports your web server has open to the internet? Nmap is your friend.

Nmap is a powerful command-line tool and has many options that require some reading of documentation to get the best out of (although generally straightforward). If the thought of working at the command-line scares you (presumably not if you're reading this review), then you may want a much simpler tool, or at least check out Zenmap GUI.

We use and depend on it for status state of our network gear, switches and routers. It does an excellent job of getting you the details you need to confirm all devices and products are working at the level needed. At times, it does tend to flag network switch ports and/or switches themselves as exceeding their rated capacity when frequently it was a quick blip of high traffic due to downloads, or uploads causing the max'ing of the device. Again, you can adjust the settings but then you adjust it too high and miss real activity. It can become nuisance alerting when you tend to then ignore

• NMap provides a very fast and a very thorough network "sweep" that allows you to quickly map out exactly what's on your network.
• NMap is highly configurable. The "canned" choices are very good in most instances, but using various switches and options, you can create a very specific scan and get exactly the results you're looking for.
• NMap is easy to use. Even a new administrator will be able to use the graphical version (Zenmap) with efficiency right away.

• The level of customization possible with Network Bandwidth Analyzer is very valuable. Rather than being stuck with a "one-size-fits-all" presentation, an administrator can easily create customized views, reports, and alerts so that users can have a more tailored view of the data provided by Network Bandwidth Analyzer. This has the effect of making the tool more attractive to the end user.
• The NetFlow Traffic Analyzer piece of Network Bandwidth Analyzer provides the details on bandwidth usage on the network. More than knowing how much bandwidth is being used, one is provided with detailed information on how that bandwidth is being used. This provides invaluable information for capacity planning and even certain forensic tasks faced by the network engineer.
• The ability to produce network maps provides an easy way to create an attractive and functional NOC/SOC view of the entire network. Both technician and the occasional passerby can quickly determine if there are issues to be addressed. The ability to customize a map with background images and custom icons and stencils can make these maps really pop.

• 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.

Incentivized

• The ability to intuitively and quickly serve up specified information up to a dashboard for general “public” consumption, that cycles through several pages of information.
• The ability to intuitively set up alerting on bandwidth levels, instead of having to dig through all types of alerts available to find the one needed.
• Provide a pricing model based on different support levels: if I want only available update installations, don’t make me pay the same amount as those wanting full support.

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.

As far as rating for usability is concerned I would give 10/10 as NTA is very easy to use. All you need to do is install that module and ask network Team to configure the Netflow towards Server IP. [The] rest is pre-configured and reports are pre-built. Moment you receive the flows from Network all you will have is information about traffic.

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.

I know we could probably pay for it, but it would be nice if we could get to a tier 2 technician faster. Spending a couple of hours on the phone with the level 1 technician, when we have already tried the troubleshooting they are walking us through, is just a waste of time.

The training offered by SolarWinds is some of the best out there. They have several different videos that go into great detail from initial setup to advanced configurations. In addition to the view at your own pace video, they also have live training for customers that focus on a single product and you can ask questions with the folks who develop the software. I have had good success with their live sessions and getting questions answered.

Alternatives to Nmap (other IP scanners) are often much more limited in what they can do; They often only allow you to scan a specific subset of ports or a limited number of IP addresses in one command. Nmap is unrestricted in that regard. What makes Nmap stand out above the rest, is the complete network analysis package you get with it. It allows IP scanner, network deep-dives, hardware analysis, vulnerability analysis, encryption detailing, and so much more, in one free application

SolarWinds NetFlow Traffic Analyzer compared to Wireshark and PRTG Network Monitor beats it by just the simple interface. Though all are manual setup, NTA takes it a step further with graphs and reports that analyze the data for you. In comparing to Extrahop from a bandwidth comparison, Extrahop wins but Extrahop is a lot more than just a bandwidth monitoring and cost.

• Nmap with Wireshark is free, so it's been a great combo team to gather info and test.
• It's allowed us to avoid fines from false positives and to fix actual issues ourselves.
• Great for finding hosts, helps keep the network secure.

• Be prepared to answer lots of questions. When people see the data in NTA they are going to want to know why App A is talking to App B. Be ready to explain!
• Hand the keys to the NTA kingdom to the network team. They will thank you. Everyone wants to have friends on the network team, right?
• Be prepared to invest in some significant compute and storage performance to keep up with your NTA monitoring
• Running the latest firmware for your network gear is (often) required to take advantage of all the flow-monitoring. You upgrade regularly, right??
