FireMon vs. Nmap

FireMon is best used in a large environment (for example, I have >100
firewalls in my environment). It's best used when trying to improve
security posture and showing changes in firewall security over time. It
might not be the best choice for smaller environments or those that aren't concerned about security management.

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.

• PCI Reporting - After identifying which firewalls and rulesets are in scope, producing a report artifact to satisfy PCI requirements on Firewall reviews is literally a two-click operation.
• Storing Rule Metadata - FireMon stores metadata (prefilled fields, standard fields, and custom fields) for each rule in each policy which is valuable for context during firewall reviews in particular
• API - FireMon exposes most if not all of its functionality via REST API

• 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.

• Some features could be added to the existing functionality which include NAT rules usage
• Rule expiration normalization from firewalls rather than entering them in rule documentation
• .csv exports of the files from the firewall pane only gives usage for 30 days by default and that should be increased

• 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.

Once all the customization has been completed, the business is starting to see the return on investment. The visibility it provides into the network gear that is owned by other IT groups is immeasurable and has allowed us to apply standards across the board. The only thing I have concern with is their support documentation.

It save me time and I'm able to have the review - review the rule independently with using my time.

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.

FireMon has been relatively stable overall. However, there have been a handful of times where we had issues with the console. For example, we couldn't update which devices to include in a security assessment. The initial suggestion from support was to just reboot it. It seems like there weren't many other options available such as to restart services before going to the extreme of a complete reboot.

I'm not sure we have the largest implementation of FireMon out there but we do have a few 1000 devices being probed by FireMon. Overall, the system's performance has been rock solid. The console refreshes quickly and reports are generated within an expected timeframe.

FireMon technical support is awesome! They respond quickly to our requests and they are well trained and very knowledgeable about the tool. Some issues have to be referred to the development team, but technical support largely provides solutions for any issues that we may have.

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.

Implementation is fairly simple. Most issues can be resolved by referencing manuals.

I has worked with AlgoSec and while they are very similar product, I find the FireMon is easier to understand and get rolling with. While both require some learning, FireMon is by far the easier one. Once you have an understanding of how things are arranged and labeled you can easily import firewalls and begin to work on them to improve them

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'.

Firemon Is easily scalable and maintainable with any size team. Although it requires some tech debt, it is well worth the time to invest to ensure compliance is visible and reports are accurate. Although our environment is very large we do not fully utilize the scalability of the Firemon product.

• It helps us save us time in determining what change was made and by whom.
• Real time alerting is a great convenience in helping us know if something went wrong, we can immediately review the last report to determine what has changed.
• Allows us to determine what rules are not used and if said rules are still required.

• 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.
