pfSense Alternatives: 7 Platforms Compared for 2026

People go looking for a pfSense alternative for one of three reasons: Netgate withdrew the free pfSense Plus Home+Lab download in October 2023 and the licensing feels precarious (Netgate’s own post on the change); the Community Edition release cadence has slowed to the point that a package they want has moved on without them; or the box they own simply cannot run FreeBSD well.

Those are three different problems with three different answers. A drop-in replacement, a lighter-weight replacement, and an easier-to-live-with replacement are not the same product. This roundup sorts seven live platforms by which of those problems they solve, based on each project’s own documentation and licensing terms rather than a bench run.

It also does something most “pfSense alternatives” lists refuse to do: it removes the options that have quietly died. Two names that still rank well in search results are no longer safe picks, and picking one in 2026 means building a network on a product with no future.

The shortlist at a glance

Platform	Closest to pfSense on	Licensing	Inline IDS/IPS	Runs on
OPNsense	Everything. Same lineage, same feature model	Free, BSD 2-clause	Suricata, well integrated	Any x86-64
IPFire	Zone-based firewalling, VPN breadth	Free, donation funded	Suricata	x86-64 and ARM
Sophos Firewall Home	Web filtering and full UTM	Free for non-commercial use	Built in, full UTM stack	x86-64 or VM
Endian Firewall Community	UTM feature bundle, proxy-heavy	Free community edition, last built 2023	Included	x86-64 or VM
MikroTik RouterOS	Routing depth, multi-WAN	Bundled with hardware; CHR licensed	None (filter tables only)	MikroTik gear or x86
OpenWrt	Nothing, and that is the point	Free, GPL	No inline IPS	Consumer routers, x86
VyOS	Routing protocols, config discipline	Rolling free; LTS by subscription	No	x86-64, VM, cloud

The firewall platform spec matrix and picker lays most of these out attribute by attribute across 18 normalized fields if you would rather filter than read.

1. OPNsense: the actual drop-in

OPNsense is the only entry here that a pfSense administrator can move to without relearning the mental model. It forked from pfSense in 2015, it is still FreeBSD underneath, and the concepts map one to one: interfaces, aliases, floating rules, gateway groups, CARP, pfsync.

What has changed since the fork matters more than the shared history. WireGuard sits in the base system rather than arriving as an add-on, Suricata is a first-class plugin with sane ruleset management, and the project ships two major releases a year on a published schedule (release documentation).

The one thing to plan for: neither project provides a supported importer for the other’s configuration file. Rules, aliases and NAT entries get rebuilt by hand. On a home or small-office ruleset that is an evening; on a 300-rule commercial edge it is a project.

Full breakdown of the two: OPNsense vs pfSense in 2026, and the VPN-specific differences in WireGuard on OPNsense vs pfSense.

Pick it if you want pfSense with a maintained release train and no licensing question mark.

2. IPFire: the Linux answer

IPFire is the strongest non-BSD option for someone who wants a real firewall distribution rather than a router firmware. It is a purpose-built hardened Linux system, not a package you install on top of a general distribution, and its defining idea is the coloured zone model: Red for the untrusted uplink, Green for the trusted LAN, Blue for wireless, Orange for a DMZ. Traffic between zones is denied unless a rule says otherwise, so a fresh install is already segmented rather than being a blank rule table you have to fill in correctly before it means anything.

Its intrusion prevention is Suricata based, and it carries all three VPN protocols that matter: IPsec, WireGuard and OpenVPN, for both site-to-site and remote access. The project’s feature documentation specifically calls out hardware-accelerated encryption for IPsec and MLKEM as a post-quantum key exchange option, which is further ahead than most of this list. Packages come from Pakfire, its own manager, which is deliberately smaller than the pfSense or OPNsense plugin catalogues.

The tradeoffs are real. The web interface is functional rather than modern, the add-on ecosystem is thin next to the FreeBSD pair, and the project is funded by donations rather than a vendor, which shows in the pace of interface work rather than in security maintenance.

Pick it if you want Linux tooling, a small resource footprint, and a zone model that fails closed. It is also the practical answer on a general-purpose ARM board: OPNsense and pfSense CE are x86-64 only, and the ARM builds that exist are Netgate’s own, tied to its 1100 and 2100 appliances and to a thinner package set than the x86 models carry.

3. Sophos Firewall Home Edition: commercial UTM for free

This is the free, non-commercial licence of the same Sophos Firewall software sold to businesses, and it is the only entry here that hands a home user a complete UTM stack: intrusion prevention, web filtering with category control, application control, antivirus scanning and reporting, all configured from one interface instead of assembled from plugins.

The licence terms are the whole story. It is limited to four CPU cores, and as of 20 May 2025 the RAM ceiling was removed entirely, so the memory in the box is no longer the constraint it once was (Sophos community announcement). Non-commercial means non-commercial: running a consultancy from the home office it protects is outside the terms.

It is closed source, unsupported at the home tier, and you are on a vendor’s enterprise release train rather than a community one. In exchange you get web filtering that works on day one instead of after a weekend of Suricata tuning.

Pick it if filtering and reporting matter more than openness, and nothing on the network earns money.

4. Endian Firewall Community: the other UTM

Endian Firewall Community is the free edition of a commercial Italian UTM appliance, Linux based, and it inherits the same Red/Green/Blue/Orange zone colours as IPFire from the IPCop lineage they share. The published community feature set is UTM-shaped rather than router-shaped: stateful firewall, IPsec and SSL VPN, intrusion prevention, antivirus, email security, multi-WAN with failover, QoS and reporting (community edition page).

Check the release date before you commit to it. The community edition’s most recent build is 3.3.25, announced in October 2023, and the two releases before it were 3.3.15 in March 2022 and 3.3.2 in November 2020 (community release announcements). The commercial Endian product has continued on a separate and much faster train in the meantime. That gap is not abandonment — the vendor is trading, the ISO installs, and 3.3.25 added UEFI boot — but a package base last refreshed in 2023 is a different proposition from OPNsense’s twice-yearly cadence, and it is the thing to weigh rather than the feature list.

It is worth knowing about mainly because “endian vs pfsense” is a live comparison people are making, and the honest answer is that they are different shapes. Endian is a UTM built around inspecting application traffic; pfSense is a network firewall that you extend into a UTM if you want one. Endian’s routing and multi-WAN capabilities are noticeably thinner, and its community edition holds back features that the paid appliance carries.

Pick it if content and mail scanning is the requirement, the routing needs are simple, and a 2023 package base is acceptable where you are putting it. If it is not, IPFire is the better Linux answer.

5. MikroTik RouterOS: when the problem is routing, not filtering

RouterOS is the alternative for people whose pfSense box is really a router with a firewall attached. BGP, OSPF, MPLS, policy routing, per-connection classifier load balancing and VRRP are all first class, and the hardware is inexpensive enough to change the economics of a multi-site build.

Two constraints decide whether it fits. First, there is no inline IPS: RouterOS gives you filter, mangle and RAW tables, and that is the security ceiling. Second, if you want to run it on your own x86 hardware, the Cloud Hosted Router licence tiers apply. The free tier runs indefinitely but is capped at 1 Mbps of upload per interface, which is a lab licence, not a firewall. The perpetual licences that lift it are p1 at 1 Gbps per interface for $45, p10 at 10 Gbps for $95, and unlimited for $250, with a 60-day trial to test a higher tier first (CHR licensing documentation). On MikroTik’s own hardware the licence is included, which is why the cheap hEX and RB5009 boxes are the usual entry point rather than an x86 install.

Pick it if routing protocols and multi-WAN behaviour are the reason you are shopping, and you accept doing inspection elsewhere.

6. OpenWrt: the lightweight replacement

OpenWrt is not a pfSense competitor and does not try to be. It is Linux router firmware for embedded hardware, and it is the right answer when the pfSense box is overkill: a travel router, a second perimeter for an isolated VLAN, a small branch site, or a consumer router you want to keep patched after the vendor abandons it.

It handles nftables firewalling, WireGuard, VLANs and DNS filtering competently on hardware that costs less than a mini-PC’s power supply. What it lacks is inline intrusion prevention, a comparable plugin ecosystem, and the state synchronisation features that keep a pair of firewalls in step.

Pick it if the requirement got smaller rather than larger, or the hardware is ARM and cheap.

7. VyOS: firewalling as configuration

VyOS is a Linux routing platform driven entirely from a structured CLI with commit and rollback, closer in feel to a Juniper device than to a web-managed appliance. Configuration is a text artifact you can diff and version, which is exactly right for people who treat the network as code and exactly wrong for people who wanted a GUI.

The licensing needs a moment’s attention: rolling-release images are published openly and the source is open, while stable LTS binaries sit behind a subscription, with free access programmes for contributors and some non-commercial users. Budget for that before standardising on it.

Pick it if you want reproducible, version-controlled network configuration and have no interest in a web interface.

The two you should stop shortlisting

Untangle / Arista NG Firewall. Untangle was a genuine pfSense alternative for a decade, and it still appears near the top of most alternatives lists. It should not. After Arista’s acquisition, Home subscriptions were taken end of sale, with 30 April 2024 set as the last day to renew an existing one, dropping those installations back to the free tier’s basic routing and security features (Arista’s end-of-sale notice). The Q-series appliances followed: Arista announced end of sale for the Q4, Q8, Q8W, Q12 and Q20 on 11 March 2026, with 30 June 2026 as the last order date (end-of-sale advisory). The software continues under Arista, priced and sold to businesses, with existing customers pointed at virtual editions or VeloCloud Edge hardware. As a home or homelab pfSense replacement, that door is shut.

Zeroshell. The final release was 3.9.5 in January 2021. The author posted the end-of-life notice on 18 April 2021, committed to security updates only until 30 September 2021, and said the domain would be decommissioned or sold on the same date (archived copy of the notice; the live URL is gone, as promised). Nothing has shipped since, and zeroshell.org now refuses connections. Anything still running it is running a five-year-old, unpatched package set facing the internet.

Both still surface in search results, which is precisely why they are worth naming.

Hardware does not change when the software does

Every x86 option here runs on the same hardware you would have bought for pfSense, so a platform switch is rarely a hardware purchase. The sizing rules also survive the move: Intel NICs over Realtek, enough single-thread performance for VPN throughput, and real headroom before enabling inspection. The tiering in firewall hardware tiers: Celeron vs N100 vs i5 applies unchanged, as does the appliance comparison in Protectli vs Netgate.

If the honest answer is that you no longer want to administer a firewall at all, the appliance path is a legitimate exit rather than a defeat: Firewalla vs pfSense covers what you give up and what you get back.

What to actually pick

• Leaving pfSense but keeping the same job: OPNsense. Nothing else is this close.
• Leaving FreeBSD behind: IPFire. Endian only if content and mail scanning is the point and its 2023 community build is acceptable.
• Wanting filtering that works out of the box: Sophos Firewall Home Edition, if the network is genuinely non-commercial.
• Routing is the real workload: MikroTik RouterOS, or VyOS if you want the configuration in version control.
• The requirement shrank: OpenWrt.
