Nmap
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.

If there are a number of different protocols and devices to monitor PRTG is really an all in one solution. There are network specific solutions, telephony solutions, server solutions, etc - but this tool can do anything. Even if you don't use this tool as your main "monitoring solutions" every IT professional should have access to this tool for at least troubleshooting purposes.If you are looking for something specific built for a task you may be able to find [a] more direct and easy tool to use that would be easier and quicker to setup as customization is not needed.

Nmap
- 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.

PRTG
- Very, very configurable. You can create all kinds of monitors for all kinds of things. Plus it has loads of suggestions out of the box. It can get complicated but monitoring is complicated. Pretty decent interface and good support - active community.
- I really liked how easy it was to add alerts by SMS. So easy to setup.
- I like their sizing models (for purchase). We're actually small enough that we are free. But it's not free as in stripped down - it's free because we don't use many "sensors" and don't honestly have the need.

Cons
Nmap
- 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.

PRTG
- The probe service can be quite resource-intensive. This can cause false-positive readings from some sensors sometimes.
- The software gets updated very regularly. Whilst this is usually a good thing to fix bugs etc, it does meantime downtime of the monitoring quite often while they are installed.
- The ability to create Maps from Libraries. Very specific issue but a lot of people have been asking for it for years and it is still not available.

The tool is very intuitive to use and it is Windows-based (everybody knows how to use Windows) so it's easy to get into. Every time is setup in a hierarchy so if you have a good initial hierarchy design, it will really reduce administrative effort down the road.

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 am giving this a 6 simply because I have never had to contact support. The online documentation is adequate for most things, and the user-maintained knowledgebase is excellent. The few times I have run into issues that were not easily resolvable with intuitive UI, I was able to find the answers that I needed either in the PRTG-provided documentation, the knowledgebase, or with a quick online web search.

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

I have deployed and tested three products for evaluation I found [PRTG Network Monitor] very easy to deploy, the deployment literally took not more than one hour including basic configuration and network discovery. After deployment few configuration changes and creation of maps, reports and little tweaking is required. [Then] it would go through its process of recommendation that took some time to complete, while [on] other hand other software's took lot of time to install and configure. And features were also missing, which resulted in decision in favor of [PRTG Network Monitor].

- Positive return as it's open-source (free) on all OS's.
- If a person is not used of the command line there are a ton of front ends that make it point-and-click so the learning curve is good. That cuts down on time and manpower.

- The ability to analyze multiple pieces of information in one place, especially with historical data, has saved our IT department time and headaches. It would be so much more difficult to trace an issue without PRTG, just relying on event logs and an open task manager window.
- The cost is not cheap, so it's an expense that hits the bottom line like everything else. Figure in hardware costs as well, ideally a server outside of your main environment.
- I keep saying this, but the historical data piece is worth so much. There's really no good way to collect all of that information in one place without something like PRTG. And that definitely saves time and money in the long run.
