FireMon vs. Tenable Nessus

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.

It is an excellent tool for scanning servers, workstations, and network devices to identify missing patches and misconfiguration; we regularly use it to confirm patch effectiveness after the update; it also helps us for preparing audits such as iso 27001, and regulatory requirements, it also helps us to identify open ports and services that violate security.

• Give good real time reporting for anyone making a change to any of our firewalls
• Provides good reporting tools that are out of box
• Provide good customization tools that is specific to our needs
• Upgrades are a simple process and support does relatively well with assisting us.

• Nessus is best at performing vulnerability scans, in fact, it gives findings and moreover accurate findings of the assessments. It does not do penetration testing or exploit the vulnerabilities because it is concerned about scanning the systems/applications.
• In fact, Nessus has multiple profiles/policies to perform different types of scans such as, scans oriented for PCI-DSS, malware scans, web application scans, bad shell shock detection scan to name a few.
• Nessus has the ability to classify the vulnerabilities into risk-based categories from critical to even informational which I think is one of the things that separates Nessus from other vulnerability scanners.

• 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

• The tool has lots of options for setting up before scanning any device, this methodology could be simplified further with default configuration for various devices predefined, anyhow we can use this technique by making use of policies.
• For advanced users we cannot disable the plugins inside the plugin groups, we can enable the whole set of plugins at a time, for few hundreds its ok, but thousands of plugins are of waste of resource and time.

The shell is locked out and we can't run any general centos commands. The implementation and maintainence of the arch is very complex. Even with the right identifiers on log messages the log collection keeps failing. The warning messages on the device are ambiguous. The log messages on firemon are a bit confusing and don't show the exact issue.

Nessus is best and easy to use application for Vulnerabilities finding and reporting, it has multiple platforms and wide scope covering almost all devices for security improvement so far, thus we are very likely to continue its services.

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

Tenable Nessus is a great product and provides a lot of value, but it is difficult to set up and use and the amount of data it generates can be overwhelming. It does help us prioritize based on the severity of the detection, however there are sometimes mitigating factors that we have implemented that Nessus does not account for, which causes lots of noise in the reports.

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.

I haven't needed to contact support yet. But issues are easily solved with a quick internet search which means support and by extension, the larger community are involved and knowledgeable.

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

Sometimes when we identify a vulnerability with Nessus that has an exploit, we made a proof of concept with Metasploit in order to show to the IT managers the importance of the software/hardware hardening.

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.

• FireMon's Compliance Reporting provided an immediate and tangible benefit
• FireMon helps identify egregious or erroneous rules quickly across multiple platforms
• FireMon took our audit process from an Excel spreadsheet into a far more advanced process with readily available context for reviewers

• Nessus certainly has a positive impact while me while performing my job, either as security research, or performing vulnerability assessments for clients. It gives a lot of information about the system/application after performing scans. The number of false positives is also less compared to other vulnerability scanners.
• The professional edition is very useful as policy templates available in this edition are very handy and useful even to perform compliance scan like PCI DSS scan.
• Also, the ability to export the scan results into reports in formats like HTML, PDF is very useful which could be for performing system/application reviews.
