    Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.
    As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.
    Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.

    Untangle is very strong in the "traditional" sense of security. That means an edge appliance that either works with an existing router or is the router itself (recommended). This approach has also been adapted well to cloud environments in order to protect virtual servers and VDI workstations. As mentioned earlier, many schools are using cloud-based filtering for their 1:1 solutions for their students. This is an area where Untangle is unable to serve. Some have used an instance of Untangle in the cloud with VPN to serve their remote needs, but it is not the same as solutions that are designed for cloud-based filtering of devices without VPN.

    Pros
    Nagios Enterprises
    • Monitoring of services is one of the biggest benefits for our company. Being able to respond in a timely fashion keeps business smooth.
    • Hardware and device monitoring are easy to set up with proper parameters.
    • Notification to key staff to be able to respond quickly makes issues go away faster.

    • Web Filtering is strong, and can also do application fingerprinting to allow Facebook, but not Facebook games. Secondly, a separate partition called a "rack" can be set up to give one subnet or group of users different web filtering policies than another. For example, teachers would get more freedom to browse the web than students at a school.
    • Built-in SD-WAN connectivity as part of your license. IPSEC tunnel creation is also amazingly easy.
    • Will install on any x86 hardware created in the last 5-10 years. Ram and processor requirements per user are very low.
    • Reporting is phenomenal, however you can get death by details very easily.

    Cons
    Nagios Enterprises
    • Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
    • Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.

    • The full suite can be expensive for business but will be powerful enough.
    • The full suite for home or small office isn't that bad of a price but may be out of reach for most home users but remember the basics are FREE so anyone can get started with it.
    • I would like to see it promoted for mid to large businesses as I think it can handle it.

    We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.

    Usability
    Nagios Enterprises
    The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.

    Support Rating
    Nagios Enterprises
    I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.

    Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].

    Untangle NG Firewall has a partnership with third parties to provide an amazing suite of applications. You pay for those. With free software, you have to wait for it to be updated. With Unifi, the hardware was too underpowered to do anything meaningful. I don't mind the monthly fees because these companies update quickly; they have a reputation to maintain.

    Return on Investment
    Nagios Enterprises
    • With it being a free tool, there is no cost associated with it, so it's very valuable to an organization to get something that is so great and widely used for free.
    • You can set up as many alerts as you want without incurring any fees.

    • It's allowed us to be PCI compliant which we need to do business.
    • It's allowed us to not only be PCI compliant but follow best practice to be actually as secure as we can be.
    • It's really presented us with a lot of flexibility in terms of how we connect to other services.
    • There is some maintenance, but it's very minimal.
