Quick take
Already sold on pfSense?
In this articleShow
Short answer: pfSense turns a small PC or appliance into an enterprise-grade firewall and router with VPN, traffic shaping and intrusion detection. pfSense CE (Community Edition) remains free and open source — version 2.9.0 shipped in 2026. pfSense Plus is Netgate's commercial edition with newer features and support; since Netgate ended its free Home+Lab license in 2023, running Plus on your own hardware requires a paid license, though it comes included with Netgate appliances. For home labs and small offices, pfSense CE (or its fork OPNsense) is still an excellent choice.

Hardware choices
Option | Good for |
|---|---|
Netgate appliance (includes Plus) | Small businesses that want support |
Mini PC with two or more Intel NICs | Home labs and power users running CE |
Virtual machine | Labs and testing |
Avoid hardware with poorly supported network chips; Intel NICs are the safest choice.
A sensible home or small-office setup
- Separate LAN, guest and IoT VLANs, with rules blocking IoT from reaching the LAN.
- Install pfBlockerNG for DNS-based ad, tracker and malware blocking.
- Add Suricata in IDS (alert-only) mode first, then enable blocking once tuned.
- Set up WireGuard for remote access instead of opening ports.
- Restrict the admin interface to the LAN and enable two-factor login where possible.
- Back up the configuration after every change.
pfSense vs. OPNsense
OPNsense is a 2015 fork of pfSense with a modern interface, frequent releases and a fully open-source model. Many home users have moved to it since the Home+Lab change. pfSense remains the more widely documented option, with a very large community. Both are excellent; choose based on interface preference and support needs.
Weak spots
- Learning curve — networking knowledge is needed.
- Licensing changes for Plus on non-Netgate hardware.
- Overkill for households that just need a good consumer router (see our home network checklist and Firewalla review).
Verdict
pfSense remains one of the most capable firewall platforms available, and CE is still free. Small businesses benefit from Netgate hardware with Plus; enthusiasts and home labs can run CE — or OPNsense — on inexpensive hardware.
