    I would recommend all system administrators use some form of network monitoring if they are not already doing so, and I'd definitely recommend people consider OpenNMS if they're shopping around. Small businesses will benefit from the low-cost of entry (it's free!), whilst getting all the enterprise features. Larger businesses can benefit from paid support plans.
    However, there's no getting around the fact that you will require some advanced networking and sysadmin knowledge to get the most out of OpenNMS, or at least, be prepared for a steep learning curve. If you don't have the resources to devote this time initially, you may struggle.

    Untangle
    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

    • 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
    The OpenNMS Group
    • We've had a few issues with delayed alerting.
    • I haven't quite figured out how to make topologies work yet, but I haven't spent a ton of time on it either.
    • We've also had a bit of trouble importing some MIBs, but that usually boiled down to working with the vendor to make sure we had the right MIBs and dependencies.

    • 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.

    OpenNMS's more attractive GUI and its price break were the main reasons our company chose to explore and use this product. However, it never managed to actually replace Nagios which had a much more established hold within the company. Perhaps we were over-monitoring, but our company claimed a $100k loss per hour of downtime.

    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
    The OpenNMS Group
    • Initial adoption required quite a lot of resources and time to get everything right. Totally worth it for us; just be prepared for a gradual process that will get better and better with time.
    • Once setup and running smoothly, it provides us with all the reporting we could hope for, at near zero cost.
    • With OpenNMS, we're able to offer a much more reliable service to our customers, and spend a lot less time dealing with issues.

    • 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.
