Snort vs. pfSense

If a colleague was looking to tighten down their network I can easily recommend Snort to them. It gives you some more peace of mind knowing that its always scanning traffic for malicious looking code. Even things your major firewalls and security hardware might miss, Snort has picked up. Its an easy recommendation for me.

pfSense is incredibly budget friendly and capable for organizations of all sizes. My specific scenario, working for a non-profit organization, requires budget consciences decisions without compromising security and function. pfSense has helped tremendously in accomplishing this. It specifically tackles advanced routing, static routing, remote access, intrusion prevention, in a single platform, mostly available for free.

• The threat intelligence from Cisco TALOS is unparalleled. This is grafted into the Sourcefire application which greatly improves security visibility. With this there are a lot of groups that you can use for white listing or blacklisting, knowing its being updated in the background without additional work from you.
• Flexible. Instead of putting a traditional firewall inline you can put a source fire appliance (or firewall with sourcefire on-board) to not only block/allow traffic, but if you insights into it, and do some forms of threat scoring.
• In depth information. Sometimes a bit overwhelming, but you are able to do more than just see alerts, you can view the full information and packets that lead to the conclusion, though the conclusion is prepared in advance for you.

• Easy to use. Good user interface design! Easy to understand and easy to set up.
• Lower hardware requirement. 3 years ago, we used an old PC to run it. Now, we have changed to a router device with Celeron CPU and 8GB RAM. It runs smoothly with a 1000G commercial broadband.

• There are plenty of false positives in the logs, but no problems noticed related to them.

• 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.

pfSense can be a very elementary firewall but can also be as comples as you want, according your needs. I'd always reccomend a HA solution when used in a company and, for bigger companies, commercial license is recommended. It's also very adptable to everyone's needs.

Snort was chosen mainly for the ease and cost. With Snort we was able to set up in a matter of minutes without any professional services needed. If you are used to packet tracing the old fashion way, this is the product for you.

PFSense is not a fully featured and supported enterprise-grade solution; however, it does offer a lot of similar functionality at a fraction of the cost for more minor requirements.

• The Sourcefire deployment has been very good at actively blocking threats that would have potentially caused loss or compromise.
• It has given us great visibility to our network.

• pfSense has only had positive impacts on our company. We are not a huge company so not having to buy licenses to get all these features have been excellent.
• I was not around when our current sysadmin decided to use pfSense, but I am assuming from day one it was probably a 100% return on investment since it does everything we need it to and it was open source software.
