Intermapper vs. Nmap

Intermapper is a light weight, quick and easy to use monitoring application. It will get you up and monitoring key infrastructure devices with a simple management interface and effective alert system that doesn't generate a lot of noise. It provides mobile device access through a web interface and is relatively inexpensive.

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.

• The best thing about Intermapper is that it is map-based. You start by building your map, which is done completely automatically. I've used many different monitoring software packages, Solarwinds, Nagios, Opmanager, and it is a royal PITA to create live maps with those.
• Another great feature is that it shows you, visually, the bandwidth utilization of your network by using "ants" and color codes. Incredibly useful.
• Alarms are very easy to setup, again much easier than the packages mentioned above.

• 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.

• Setting up probes in bulk can be difficult, so it can take a long time to get the system set up correctly to start.
• Sometimes the probes can be sensitive and report false positives.
• Interface can be a little clunky and non intuitive at times.

• 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 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. We have had the product for years and it may have been a year or better since the last time we contacted them.

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.

Intermapper is a cross between WhatsUp Gold and Nagios. WhatsUp Gold being for a less technical end-user and Nagios doing more than just SNMP scans and up down monitoring.

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

• Downtime costs money. Every minute we can get ahead of an outage is time that a plant is not sitting there waiting. We don't need to wait for a call from a plant, we know they are down immediately and we can begin troubleshooting.

• 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.
