Nagios Core

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.

pfSense

For fast-growing or SME companies, pfSense is quite suitable because pfSense already had many advanced features such as VPN and multiple WAN / LAN. As a result, we just need to pay for expensive router frequently to upgrade our infrastructure.

Pros

Nagios Core

  • 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.

pfSense

  • pfSense is an excellent firewall - It logs all of your traffic. It has packages you can install to snort bad traffic.
  • pfSense has a tool called "p0f" which allows you to see what type of OS is trying to connect to you. You can filter these results and you can also block a specific OS from connecting to you.
  • pfSense is an excellent load-balancer: (Multi-WAN and Server Load Balancing) The fail-over/aggregation works very well. This is perfect if your business uses multiple ISP's to ensure your customers are always able to access their data. Also helps with bandwidth distribution as well.
  • VPN's - I am not entirely sure if this package was free with pfSense, but it does offer the ability to use OpenVPN which is what I am familiar with.
  • They also have IPsec in the settings as well, but I am not familiar with that enough to go into any detail with it.
  • As I mentioned I do use OpenVPN the only thing I don't care for with it is I can create OpenVPN configs for each user I want to be able to VPN into the network and I assumed each one would be "unique" but this does not seem to be the case. I could be doing it wrong, but if I create a config for a specific employee I would expect only that employee should be able to use that config, but I have been able to login to everyone that I made using my credentials.
  • I mentioned earlier that pfSense had a GUI.
  • I personally really think it is cool because it has a bunch of reporting graphs for monitoring your networks. I think when I become the full-time admin at the company I am going to try to talk them into getting me a TV I can mount on the wall and display all the graphs and real-time info pfSense shows so I can monitor what is going on with the network(s) at all times. Plus I think it would look rad.

Cons

Nagios Core

  • 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.

pfSense

  • There is no API for making changes. This can be a hindrance in environments where auto-deploying something needs firewall rules or HAProxy configs updated. Since all settings are stored in an XML file and then configs are generated from that, even manually updating config files cannot be done.
  • Beware that some network cards can have issues. pfSense is based on FreeBSD, so it's best to look on their compatibility list before deploying.

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.

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.

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.

Alternatives Considered

Nagios Core

I have been using Nagios for 10+ years, so I am very familiar with it. The learning curve with SolarWinds was more difficult for me to pick up than Nagios and it wasn't as easy (at first) to duplicate, edit, etc. in SolarWinds. I genuinely think Nagios is a great product for many reasons, one of which is the unbeatable price.

pfSense

Before pfSense we were using consumer and small business rated network appliances from Linksys, Cisco, Buffalo and Netgear. We were replacing them on average of every 6-12 months because they'd fail or would offer poor wifi availability.Switching to pfSense allowed us to use professional grade switches and wifi access points, offloading all of the services that the consumer grade products took care of, onto pfSense (DHCP, DNS, routing, firewall, VPN, etc).

Return on Investment

Nagios Core

  • Much better network device performance metrics allowing to troubleshoot and do before/after changes comparisons
  • Has helped us to integrate with our Service Management tool (through other 3rd party tools)
  • Important part of our overall network health dashboard providing granular details at the device level (not end-to-end performance)
  • Cost is very convenient

pfSense

  • Moving to a FWaaS solution installed on a decent computer the initial investment was moderate to cover 50 to 250 users, but still being cheaper that a Fortinet, Cisco ASA, or a Sophos UTM.
  • Paying only for support can be a double edge knife, cause you need to identify what's the goal of the request, or your drown into a an endless list of requirements.
  • To stay in the top with the half of a regular investment pFSense gives a wide variety of plugins that will give you a deep knowledge of your security flaws and strong points.
