pfSense: Guides and Comparisons

pfSense is one of the most popular home lab and small business firewall operating systems. Simply put, pfSense will provide the best overall bang for your buck in terms of network security, flexibility, and control since it can be installed on DIY hardware. There are a lot of features built into pfSense, and many different configuration options, which can make it a little overwhelming at first.

I used pfSense in my home lab for many years, and I’ve also helped many clients implement it in their home and/or business environments. Whether you’re looking to enhance security, optimize your network, or set up advanced features like VLANs and VPNs, these guides will walk you through every step.

Why Should You Use pfSense?

pfSense is a powerful, open-source firewall and router that provides enterprise-grade features without the cost of commercial alternatives. Unlike traditional consumer-grade routers, pfSense allows for complete control over your network, offering deep customization, traffic shaping, VPN integration, intrusion detection, and more.

One of the biggest advantages of pfSense is its flexibility, since you can run it on dedicated hardware, in a virtual machine, or as part of a high-availability setup. This makes it a great option for home labs and small businesses.
