Splunk is software for searching, monitoring, and analyzing machine-generated big data, via a web-style interface. It captures, indexes and correlates real-time data in a searchable repository from which it can generate graphs, reports, alerts, dashboards and visualizations.
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: Splunk is very well suited if you have multiple log sources of related data. All of them can be correlated and tasks can be automated based on the requirement. Other than alerts, Splunk can also run a specific script of your choice, based on some defined conditions. Cons: If you have a few logs but a large number of log sources, Splunk can be very expensive.
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.
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 are using Splunk extensively in our projects and we have recently upgraded to Splunk version 6.0 which is quite efficient and giving expected results. We keep track of updates and new features Splunk introduces periodically and try to introduce those features in our day to day activities for improvement in our reporting system and other tasks.
You can literally throw in a single word into Splunk and it will pull back all instances of that word across all of your logs for the time span you select (provided you have permission to see that data). We have several users who have taken a few of the free courses from Splunk that are able to pull data out of it everyday with little help at all.
Splunk maintains a well resourced support system that has been consistent since we purchased the product. They help out in a timely manner and provide expert level information as needed. We typically open cases online and communicate when possible via e-mail and are able to resolve most issues with that method.
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).
I wanted to learn a new language that I can quickly master and implement. Splunk is easy, fun to use and best of all, it can be developed in hours not days or weeks. Splunk is fundamentally a programming language that is minimal but yet powerful enough to collect, analyze and visualize data.
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.
