pfSense vs. OPNsense: Which Firewall is Best for You?

When I first wrote this pfSense vs. OPNsense comparison in 2024, my conclusion was that you could pick either firewall and be happy. That’s still true, but it isn’t the whole picture anymore. The two projects have spent the past two years moving in noticeably different directions, and those differences are the part to understand before you commit, even if they haven’t changed which one I run. This is the updated comparison, current as of OPNsense 26.7 and pfSense CE 2.8.1.

The short version is that I run pfSense, and it’s what I’d point most people toward. The community around it is far larger, so whatever you get stuck on has almost certainly been answered already, and pfBlockerNG still has no real equivalent on the other side. OPNsense is the better pick if you want release timing you can plan around, or if the interface matters more to you than the size of the community, and I’ll be straight about where pfSense has slipped since I last wrote this. If what you actually want is one device that also handles WiFi, neither of these is the answer, which is why there’s an OpenWrt section further down.

What’s Changed Since 2024

The reason this update exists is that the gap between how these two projects operate has widened. If you’ve read an older comparison, including the previous version of this one, here’s what it’s missing:

• pfSense CE releases slowed down considerably. CE 2.7.2 shipped in December 2023 and the next stable release, 2.8.0, didn’t arrive until May 2025, with 2.8.1 following that September. That’s roughly a year and a half between releases of the free version.
• The free pfSense Plus path is gone. Netgate ended the free Home+Lab edition of pfSense Plus in October 2023, so running Plus on your own hardware now requires a paid TAC subscription, and pfSense CE is the free option for personal hardware.
• Downloading pfSense CE changed. Grabbing an installer now routes you through Netgate’s online store and its installer package rather than a plain download link. It works fine, but it’s an extra hoop that part of the community wasn’t thrilled about.
• OPNsense kept its rhythm. Two major releases a year in January and July, with security updates about every two weeks in between. 26.1 rebuilt the firewall rules interface, moved intrusion detection to Suricata 8, added a host discovery service, and made Dnsmasq the default DNS and DHCP combination for new installs. 26.7 landed on July 15, 2026.
• The operating system bases diverged. OPNsense 26.7 runs on FreeBSD 15.1, a stable release, while pfSense CE 2.8.x is built on a FreeBSD 15-CURRENT development snapshot and pfSense Plus has moved to 16-CURRENT.

None of this makes pfSense a bad firewall, as it’s mature, stable, and runs in an enormous number of networks, including mine. It hasn’t moved me off it. But it’s a fair thing to have in front of you before you pick, and if release timing is something you plan around, it’s the strongest argument OPNsense has.

pfSense in 2026

pfSense is a FreeBSD-based firewall and router platform maintained by Netgate. It started in 2004 as a fork of m0n0wall and comes in two versions today. pfSense CE is the free and open-source edition you install on your own hardware, while pfSense Plus is the commercial edition that ships on Netgate appliances and is only available on personal hardware with a paid support subscription. Most of Netgate’s development pace lives in Plus these days, which is on 26.03.1 as of this writing while CE sits at 2.8.1.

pfSense’s core strengths haven’t changed. The install base is huge, the documentation is deep, and there are more tutorials and forum threads for it than for anything else in this space. If you get stuck at 11pm, someone has already had your exact problem. It also has pfBlockerNG, which is still a real reason to pick pfSense, and I’ll get to that below.

That community-size advantage is measurable, and it’s the single strongest argument for pfSense. The chart below compares worldwide search interest in both projects over the past year.

pfSense is consistently and substantially more searched for, and that gap turns into more guides, more forum history, and more people who have already solved whatever you’re about to run into. It says nothing about which codebase is better, but it’s a genuine practical benefit and it’s why I’d still point a complete beginner at pfSense despite preferring the OPNsense interface myself.

OPNsense in 2026

OPNsense forked from pfSense in 2015 and is maintained by Deciso, a Dutch company that sells its own appliances and a business edition. The whole platform is developed in the open under a BSD license, and the roadmap is public. Releases show up when the calendar says they will, with major versions every January and July and small security updates roughly every two weeks in between.

The last two release cycles have been busy ones. 26.1 in January 2026 rebuilt the firewall rules screens on the newer interface framework and moved intrusion detection to Suricata 8 with a new inline inspection mode. It also added automatic host discovery and switched new installs to Dnsmasq for DNS and DHCP. 26.7 in July 2026 moved the base to FreeBSD 15.1 and started reworking interface management. WireGuard ships in the core system rather than as an add-on. Zenarmor, the application-level inspection engine with a free home tier, is built around OPNsense, and that gives it a layer-7 story pfSense doesn’t really have anymore.

User Interface

My position here hasn’t changed since the first version of this article, as I find OPNsense easier to use and more logical, meaning things are where I expect them to be. OPNsense puts everything in a left-hand menu that you can search.

pfSense uses a top menu bar that spreads settings across more places than it probably should. The interface isn’t bad, and long-time users navigate it on muscle memory, but there have been plenty of times where finding a setting took me longer than it should have.

What has changed is that the gap widened. OPNsense’s redesigned firewall rules interface in 26.1 is a real improvement to the screen you spend the most time in, and that work continued in 26.7, while pfSense’s interface hasn’t meaningfully changed in years. Whether you read that as stability or as stagnation probably tells you which firewall you’ll prefer.

Both are also very different from a consumer router, where something as ordinary as port forwarding has far more settings than you’re used to, so you’ll be reading documentation the first few times through on either platform. If you want to see how that plays out, I have guides on creating firewall rules in pfSense and pfSense port forwarding, along with the OPNsense equivalents for port forwarding and VLANs.

Feature Comparison

The core firewall features are effectively a tie, and that’s worth saying plainly. VLANs, NAT and port forwarding, multi-WAN, high availability with state sync, traffic shaping, and certificate management are all present and mature on both. The differences that actually matter are in the rows below.

Packages: pfBlockerNG vs. Zenarmor

Out of the box the two firewalls do nearly the same things, so the real deciding factor is the add-on ecosystem, and each side has one heavyweight the other doesn’t.

pfSense has pfBlockerNG, which combines DNS blocklists, IP reputation lists, and GeoIP blocking into one package. It’s the single feature that keeps a lot of people on pfSense, and I understand why, because once it’s dialed in it quietly handles ad blocking and inbound noise filtering for the whole network. There’s no direct OPNsense equivalent, though Unbound blocklists cover basic network-wide ad blocking and the AdGuard Home plugin covers the rest for most home setups.

OPNsense has Zenarmor, an application-level inspection engine with a free tier for home use. It gives you per-device app and web category visibility and blocking, which is the kind of feature that used to require commercial firewalls. OPNsense 26.1 also added an optional threat intelligence plugin that feeds curated block indicators straight into the firewall, so if layer-7 visibility matters to you, this is OPNsense territory now.

My advice here is the same as it’s always been. Write down the two or three add-ons you actually plan to run, then confirm they exist on the firewall you’re leaning toward before you commit, because that one check decides this comparison for a lot of people.

VPN Support

This category is close to a dead heat. Both firewalls handle WireGuard, OpenVPN, and IPsec, both do site-to-site and remote access configurations, and the only practical difference is that OPNsense ships WireGuard in its core system while pfSense installs it as a package.

If you want the exact steps, I have tutorials for WireGuard on pfSense, WireGuard in OPNsense, and OpenVPN on pfSense.

The client side is the part people underuse. Because both firewalls can act as a VPN client, you can point one at a commercial provider like NordVPN. From there you route a specific subnet or IP range through that tunnel while everything else takes the normal path. Nothing on the client devices needs configuring, which is a much cleaner setup than installing a VPN app on every machine in the house.

pfSense vs. OPNsense vs. OpenWrt

This question comes up constantly, so it’s worth settling. OpenWrt is a different kind of tool. pfSense and OPNsense are FreeBSD-based firewall operating systems meant to run on dedicated x86 hardware with wired ports. OpenWrt is a Linux-based system that runs on hardware you probably already own, like consumer WiFi routers, travel routers, and small ARM boards. It replaces the manufacturer firmware and gives you real control over routing, VLANs, and WiFi on a single device.

Pick OpenWrt when you want one low-power box that does routing, firewalling, and WiFi together, or when you’re flashing a router you already have. Pick pfSense or OPNsense when you want a dedicated firewall with heavier features like intrusion detection, serious VPN throughput, and high availability, and you’re pairing it with separate access points. WiFi is the clearest dividing line, because FreeBSD’s wireless support is weak and neither pfSense nor OPNsense is a good WiFi router, while that’s exactly what OpenWrt was born to do.

What to Run Either One On

The hardware question matters more than the software question for most people, because both firewalls will run happily on modest gear. What you actually need is decent Intel networking and enough CPU for whatever throughput your connection requires, and beyond that the choice comes down to whether you’d rather buy an appliance or build something.

• If you already own a small PC: add a dual-port Intel i226 card and you have a firewall for the cost of the NIC. This is the route I’d take before buying anything, and it’s the cheapest way to try both.
• If you want one box that runs either OS: the Beelink EQ14 is the mini PC I keep coming back to for this, and it’s inexpensive enough that installing both and switching between them is easy.
• If you want a purpose-built appliance without tying yourself to one vendor’s OS: the Protectli Vault V1410 is fanless, has multiple Intel ports, and runs either firewall without any fuss.
• If you picked pfSense and want zero setup friction: the Netgate 1100 for a smaller connection, or the Netgate 2100 if you want more headroom. Both ship with pfSense Plus preinstalled, which is the easiest path onto the paid version.

I go into a lot more depth on both sides, including where the throughput ceilings actually sit, in my guides to the best pfSense hardware and the best OPNsense hardware.

Virtualizing is the other option and it’s the one I’d suggest if you’re still undecided, since you can run both and switch between them in an afternoon. I have guides for installing pfSense on Proxmox and installing OPNsense in Proxmox. You’ll want a supported network card, and I’d think carefully before making your hypervisor a single point of failure for the household’s internet.

Which One Should You Run?

• Starting fresh with a home lab or self-hosted setup: pfSense. This is what I run, and the deciding factor is the community, because the volume of existing documentation and forum history will save you more time than any interface preference costs you. pfBlockerNG is the other reason.
• You want release dates you can plan around: OPNsense. Fixed January and July majors with security patches every couple of weeks is a real advantage over pfSense CE’s recent pace, and the interface is the one I find easier to navigate.
• Already running either one and it works: keep it. Your rules already exist, and rebuilding a firewall config to end up in roughly the same place is not a good weekend. Switch when you have a reason, not a version number.
• Want an appliance with commercial support behind it: Netgate hardware with pfSense Plus is the strongest option, especially in the US. Deciso sells supported OPNsense appliances too, though they’re easier to buy in Europe.
• Want WiFi built into the same box: OpenWrt on capable hardware, or step back and consider a UniFi Cloud Gateway if you’d rather have a polished all-in-one ecosystem than a DIY firewall.
• Business network: either, through their paid tiers. That’s what TAC subscriptions and OPNsense Business Edition exist for, and support contracts matter more than feature tables when the network is how you make money.

Both of these firewalls remain far more capable than anything that came with your ISP contract, and both will teach you more about networking than any consumer router ever will. I run pfSense, and that’s still where I’d send most people, because the size of the community is worth more day to day than anything on the feature list. The honest caveat is the one above: the free version’s release pace has slowed, and if that bothers you, OPNsense is a completely reasonable place to land. It’s the one comparison where I’d tell you my answer and still expect plenty of people to pick the other one.

If you’re torn, do what I always suggest and spin both up as virtual machines, click around for an evening each, and you’ll know. Once you’ve picked one, set up your VLANs and a DDNS hostname, and read up on updating safely before your first upgrade. The usual note on anything security-related applies too: this space changes constantly and nothing here is a guarantee, so whichever firewall you pick, keep it updated and check your exposure from time to time.
