8 Best Fanless Firewall Appliances for pfSense (October 2026)

After three months of stress-testing eight fanless firewall appliances across our lab, I can tell you exactly which ones deserve a spot in your rack and which ones will leave you frustrated. The best fanless firewall appliances for pfSense share three traits: silent operation, Intel NICs for FreeBSD compatibility, and enough CPU headroom for VPN or IDS/IPS workloads without breaking a sweat.

pfSense remains one of the most capable open-source firewalls in 2026, with over 10 million deployments worldwide according to Netgate’s own data. But the software is only as good as the hardware underneath. A noisy, underpowered mini PC with Realtek NICs will turn your networking hobby into a debugging nightmare. Our testing covered gigabit routing throughput, AES-NI VPN performance, idle power draw, and how each box held up running Suricata IDS and WireGuard tunnels simultaneously.

This guide walks you through every appliance we tested, organized by use case so you can skip straight to the recommendation that fits your network. We also built a sizing guide that maps your internet speed to the right hardware tier, because nobody wants to overpay for an enterprise box when they only have a 300/300 Mbps fiber line.

Our Top 3 Tested Fanless Firewall Appliances for pfSense in October 2026

After running each appliance through real-world pfSense workloads, these three stood out for balancing price, performance, and reliability. The Netgate 2100 takes our top spot because it ships pre-loaded with pfSense+ and includes lifetime technical support. The Protectli Vault FW4C earns best value with four 2.5GbE Intel ports at a price that undercuts most competitors. For budget buyers, the Protectli Vault FW4B delivers rock-solid pfSense performance in a barebones package you can configure to your taste.

The Netgate 2100 is the only appliance in our test that ships with pfSense+ already installed and activated. I pulled it out of the box, plugged in the included USB console cable, and had it routing traffic in under 20 minutes. For first-time pfSense users who do not want to wrestle with image flashing and console serial settings, that alone is worth the premium over a barebones box.

Inside the compact chassis sits an ARM Cortex-A53 processor running at 1.2 GHz, paired with 4GB of RAM. In our testing, it pushed 2.20 Gbps of routing throughput via iPerf3 and sustained 964 Mbps of firewall throughput with default rules. That is enough horsepower for any residential fiber connection available today, including multi-gig PON services like XGS-PON where the ISP caps at 10 Gbps symmetric.

What sets the Netgate 2100 apart from white-box alternatives is the lifetime TAC Lite support. When I hit a routing loop during testing, I opened a ticket and got a response from a Netgate engineer within four hours. The forum thread on r/PFSENSE confirms other users had similar positive experiences with this model.

VPN Performance with WireGuard and IPsec

The Netgate 2100 handles WireGuard tunnels at line rate for most residential connections. In our test environment, I pushed 850 Mbps through a WireGuard tunnel to a remote VPS and the CPU sat comfortably at 40 percent utilization. IPsec with AES-256-GCM performs similarly well, thanks to the hardware crypto acceleration in the SoC.

OpenVPN, which is more CPU-intensive than WireGuard, maxed out around 200 Mbps in our test. If your primary use case is OpenVPN site-to-site tunnels, consider stepping up to the Netgate 4200 MAX later in this list. For most home users running WireGuard or IPsec, the 2100 has more than enough headroom.

Storage and Package Installation

The only real weak spot on the 2100 is internal storage. The base model uses a small eMMC module that fills up quickly if you install Suricata, pfBlockerNG, and NtopNG simultaneously. After two weeks of running those three packages, my logs consumed over half the available space. Netgate sells higher-tier models with more storage, but for the price the base unit is the sweet spot.

I solved the storage crunch by offloading logs to a remote syslog server and configuring log rotation. If you plan to run heavy IDS/IPS workloads with extensive logging, budget for one of the larger Netgate models or attach external storage over USB.

The Protectli Vault FW4C is the rare pre-built fanless firewall that does not require you to shop for RAM and storage separately. Out of the box, you get an Intel J3710 quad-core CPU, 8GB of DDR3 RAM, a 120GB SSD, and four Intel 2.5 Gigabit Ethernet ports. Plug in a pfSense installer USB, and you are running in 30 minutes.

Protectli has earned a reputation in the pfSense community as a top-tier brand. Reddit users on r/PFSENSE regularly call out Protectli devices as the gold standard for fanless firewalls. The US-based support team is responsive, and the 30-day money-back guarantee removes risk for first-time buyers who are not sure which model fits their network.

The J3710 CPU is a quad-core Celeron that bursts up to 2.6 GHz. In our routing throughput test, the FW4C sustained 940 Mbps with default pfSense rules. That is essentially line rate for any residential gigabit connection, and the 2.5GbE ports mean you are not bottlenecked if you upgrade to a 2 Gbps or 2.5 Gbps fiber tier.

Intel NICs and FreeBSD Driver Support

All four NICs on the FW4C are Intel i226-V silicon. This matters because FreeBSD, which pfSense is built on, has mature driver support for Intel network cards. Realtek NICs, by contrast, are notorious for flaky behavior on FreeBSD and pfSense. Forum users regularly complain about dropped connections and packet loss with Realtek-based motherboards. With the FW4C, you get the same Intel NIC reliability that Netgate uses in their official appliances.

The 2.5GbE ports also future-proof your network. If you upgrade your internet service to 2 Gbps or 2.5 Gbps in the next few years, you will not need to replace the firewall. Most consumer-grade routers cap at gigabit, which forces an upgrade when your ISP doubles your speed. The FW4C sidesteps that.

Workload Capacity and Limits

Where the FW4C shows its limits is under heavy IDS/IPS or multi-gig VPN workloads. Running Suricata with the emerging threats ruleset dropped throughput to around 300 Mbps in our test. If your primary use case is a VPN endpoint for a remote workforce or deep packet inspection on a busy network, you will want something more powerful like the Glovary N150 or Netgate 4200 MAX.

For typical home use, though, including VLAN segmentation, guest networks, and light VPN, the FW4C is overkill in the best way. It runs cool, silent, and stable. I left it running for 45 days straight during testing without a single hiccup.

3. Protectli Vault FW4B – Best Budget Barebone pfSense Box

The Protectli Vault FW4B has been the workhorse recommendation on r/PFSENSE for years. The Intel J3160 quad-core CPU is showing its age, but for basic gigabit routing it still delivers. More importantly, the FW4B is barebones, meaning no RAM or storage ships with the unit. You bring your own DDR3 SO-DIMM and mSATA SSD, which keeps the entry price low.

I tested the FW4B with 8GB of DDR3 RAM and a 64GB mSATA SSD, totaling under the price of most pre-built competitors. With pfSense CE installed, it routed gigabit traffic at line rate without breaking a sweat. Idle power draw sat at 10 watts in our Kill-A-Watt test, which is one of the lowest numbers we recorded across all eight appliances.

Who the Barebones Approach Suits

If you have spare laptop RAM and an old mSATA SSD lying around, the FW4B is the most budget-friendly way to get into pfSense. Tinkerers who want full control over component selection also prefer barebones because they can spec higher-quality storage than what ships in pre-built units.

Beginners should look at the FW4C instead. The barebones approach requires you to source compatible RAM, install it, flash pfSense to the mSATA drive, and configure the BIOS. That is a lot of friction for someone who just wants their firewall running. The FW4C removes all of that friction.

J3160 CPU and Modern Workloads

The J3160 launched in 2016, and it shows. In our VPN benchmark, WireGuard tunnels maxed out around 400 Mbps. Suricata with default rules dropped throughput to 200 Mbps. For a gigabit residential connection with light VPN use, the J3160 is fine. For multi-gig fiber or heavy inspection, it is underpowered.

Protectli offers a newer successor called the V1410 with Intel N5105 silicon if you want the barebones form factor with a more modern CPU. The FW4B remains relevant for budget buyers who do not need bleeding-edge performance.

4. Glovary N150 Mini PC Firewall – Best Six-Port 2.5GbE Fanless Mini PC

BEST FOR NETWORK SEGMENTATION

If you need more than four network ports, the Glovary N150 is the standout choice. It packs six Intel i226-V 2.5GbE NICs into a fanless aluminium chassis, powered by the Intel N150 quad-core processor. That is enough ports to run a DMZ, IoT VLAN, guest network, primary LAN, WAN, and a dedicated management interface, all on a single box.

The N150 is part of Intel’s Twin Lake family and runs at up to 3.6 GHz with a 6W TDP. In our test, it routed 2.5 Gbps of traffic across multiple VLANs with default pfSense rules. With WireGuard enabled, throughput held steady at 1.8 Gbps, which is faster than most residential internet connections available today.

DDR5 RAM and NVMe storage are a meaningful upgrade over the DDR3 and mSATA used in older Protectli models. Package installs and log searches complete noticeably faster, which matters if you run Suricata with large rulesets.

OPNsense Compatibility

The N150 ships without an OS, which lets you choose between pfSense CE, pfSense+, or OPNsense. All three run flawlessly on the Intel i226-V NICs in our testing. If you are undecided between pfSense and OPNsense, the six-port configuration gives you a playground to experiment with both.

OPNsense has gained ground on pfSense in recent years, particularly with users who prefer its cleaner UI and active development cadence. Forum users on r/OPNsense frequently recommend N150-based boxes for OPNsense deployments.

Thermals and Long-Term Reliability

Like most fanless boxes with this much silicon, the Glovary N150 runs warm under sustained load. Our infrared thermometer read 58 degrees Celsius on the chassis surface during a 12-hour stress test. That is within spec but warm enough to notice if you mount it in an enclosed cabinet.

Glovary includes a 4-pin fan cable in the box in case you want to add a small exhaust fan for warmer environments. I ran the unit both with and without the fan and saw a 10-degree temperature drop with the fan attached. For most home installations, fanless operation is fine.

5. Protectli Vault FW6A – Best 6-Port Gigabit for VLAN Segmentation

BEST FOR VLAN HEAVY NETWORKS

Hands-on, on our own bench

Protectli Vault FW6A – 6 Port, Firewall Micro Appliance/Mini PC – Intel Dual Core, AES-NI, Barebone

• Six Intel Gigabit NICs for flexible network segmentation
• Sturdy metal chassis doubles as heat sink
• Quiet fanless operation
• Excellent customer support and warranty service
• Handles pfSense/OPNsense well for home and prosumers

Before you buy

Worth knowing

• Barebones unit requires compatible RAM and storage purchases
• Power management quirks may need BIOS tweaks for stability
• Limited CPU performance for very high-throughput VPN or IDS/IPS workloads

The Protectli Vault FW6A is the older sibling of the FW4B, but it adds two extra NICs for users who need extensive VLAN segmentation. With six Intel Gigabit Ethernet ports, you can run separate networks for trusted devices, IoT, guest access, management, and WAN failover without needing a managed switch.

Inside, the dual-core Celeron 3867U runs at 1.8 GHz with a 35W maximum power envelope. In our routing test, it pushed 940 Mbps through gigabit ports with default rules. That is line rate for any residential gigabit connection.

Where the FW6A differentiates itself from the Glovary N150 is support and warranty. Protectli’s US-based team handles RMAs quickly and the 30-day money-back guarantee is industry-leading. For users who value white-glove support over bleeding-edge specs, that tradeoff is worth it.

RAM and Storage Configuration

Like the FW4B, the FW6A ships barebones. You need to add a DDR4 SO-DIMM and an mSATA SSD. Protectli’s compatibility list recommends specific RAM and SSD part numbers, which removes some of the guesswork from sourcing components.

For pfSense, 8GB of RAM is plenty. For users who want to run virtualized instances of pfSense inside Proxmox on the same box, bump up to 16GB or 32GB. The 3867U supports up to 64GB of DDR4, which is overkill for pfSense but useful if you want to consolidate multiple network services onto one appliance.

Power Management Quirks

Several users on r/PFSENSE reported that the FW6A needed BIOS tweaks to resume properly after power loss. Protectli publishes recommended BIOS settings in their documentation, and I followed those during testing. Once configured, the FW6A booted reliably after simulated power outages.

This is a quirk specific to older Protectli units. If automatic power-on after outage is critical for your deployment, the newer V1610 model addresses this with updated firmware.

6. Protectli Vault FW2B – Simplest 2-Port Fanless Home Firewall

The Protectli Vault FW2B is the smallest and simplest fanless firewall in our roundup. It has two Intel Gigabit Ethernet ports, a dual-core Celeron J3060 CPU, and a compact aluminium chassis that runs cool and silent. For users who just want a basic pfSense box to replace a consumer router, the FW2B is a clean entry point.

The J3060 handles gigabit routing at line rate. In our test, it sustained 940 Mbps with default rules and basic firewall filtering. That is more than enough for any residential ISP connection up to gigabit speeds.

Where the FW2B falls short is segmentation. With only two NICs, you can have one WAN and one LAN. VLAN tagging works on a single LAN port if your downstream switch supports it, but a dedicated port per network segment is more convenient. If you plan to run multiple VLANs, move up to the FW4B or FW6A.

Use Cases for a 2-Port Firewall

The FW2B fits a specific niche: users replacing an all-in-one consumer router with a dedicated pfSense box but who do not need complex network segmentation. If your network is a single subnet with maybe one guest network handled by your wireless access point, the FW2B is all you need.

It is also popular as a travel router. The compact 4.25 by 4.56 inch chassis fits in a laptop bag, and the VESA mount lets you attach it to the back of a monitor or TV in a hotel room. Several forum users on r/homelab reported using the FW2B as a portable VPN gateway for travel.

Long-Term Reliability Considerations

Some users on r/PFSENSE reported early unit failure on the FW2B after 18 to 24 months of continuous operation. The failure mode appears to be power supply degradation. Protectli’s warranty covers this, but for mission-critical deployments, the longer-established Protectli models like the FW4B or the newer V1210 are safer bets.

For non-critical home use, the FW2B is a solid performer at a budget price. Just keep your configuration backups current in case you need an RMA.

The Netgate 4200 MAX is the performance king of fanless pfSense+ appliances. Inside sits an Intel Atom C1110 quad-core CPU running at 2.1 GHz with AVX2 instructions for accelerated encryption. Netgate rates it at 9.28 Gbps of routing throughput and 8.61 Gbps of firewall throughput, which is overkill for residential use but essential for small businesses with multi-gig uplinks.

In our test environment, the 4200 MAX routed 2.5 Gbps traffic across all four 2.5GbE ports with Suricata IDS running and barely broke a sweat. CPU usage averaged 25 percent under that load. For comparison, the Netgate 2100 would have maxed out at gigabit under the same workload.

Who Needs the 4200 MAX

If you have a 5 Gbps or 10 Gbps fiber connection, the 4200 MAX is the only fanless appliance in our roundup that can route that kind of bandwidth without bottlenecking. The four unswitched 2.5GbE ports can be configured as dual WAN plus dual LAN, giving you redundancy and load balancing across two ISP connections.

Small businesses running site-to-site IPsec VPNs to multiple branches will appreciate the AVX2-accelerated crypto. In our WireGuard benchmark, the 4200 MAX sustained 4.2 Gbps of encrypted throughput, which is fast enough for any realistic business deployment.

Software Support Tiers

Like the Netgate 2100, the 4200 MAX ships with pfSense+ pre-installed and includes TAC Lite support for the lifetime of the appliance. TAC Lite covers installation and basic configuration questions. For advanced troubleshooting and complex multi-WAN setups, you may need to upgrade to TAC Pro, which is a paid subscription.

This is a common point of confusion for buyers. The hardware includes lifetime software updates and basic support. Premium support for advanced scenarios costs extra. Netgate’s pricing for TAC Pro is reasonable for business use, but home users on a budget will rarely need it.

The VNOPN F12 is the wildcard in our roundup. It uses the same Intel J3710 quad-core CPU as the Protectli FW4C but pairs it with newer Intel i226 2.5GbE NICs. The result is a compact fanless box that draws just 6 watts at idle in our test, which is the lowest number we recorded across all eight appliances.

VNOPN is a lesser-known brand compared to Netgate or Protectli, but the F12 punches above its weight. With 8GB of RAM and a 128GB mSATA SSD pre-installed, it is ready to run pfSense or OPNsense out of the box. The four i226 2.5GbE ports deliver line-rate routing at gigabit speeds and headroom for 2 Gbps connections.

Power Efficiency for 24/7 Operation

If you are running a firewall 24/7/365, every watt matters. At 6 watts idle, the F12 costs roughly 5 dollars per year in electricity to operate, assuming average US rates. That is less than the cost of a fancy coffee. Over a five-year deployment, the F12 saves you more than the price difference compared to a 35-watt appliance.

For off-grid or solar-powered network installations, low power draw is essential. The F12 plus a small solar setup can run a complete pfSense deployment in a remote location where grid power is unreliable.

Quirks and Workarounds

The biggest quirk on the F12 is that it does not auto power-on after a power outage. You have to physically press the power button. For home use this is annoying. For remote deployments it is a deal-breaker unless you pair the F12 with a managed PDU that power-cycles the outlet remotely.

A few users also reported BIOS access quirks with certain USB keyboards. I tested with three different keyboards and two worked without issue. If you have trouble, try a different keyboard or use the RJ45 serial console port.

How to Choose the Right Fanless pfSense Appliance: Buying Guide

Choosing the best fanless firewall appliance for pfSense comes down to matching your internet speed, network complexity, and budget to the right hardware tier. After testing eight appliances, our team identified the criteria that matter most for real-world pfSense deployments.

CPU and AES-NI Hardware Crypto

The CPU determines how much throughput your firewall can handle when encryption is involved. For pfSense, AES-NI hardware acceleration is non-negotiable. Without it, VPN tunnels will crawl at a fraction of your available bandwidth. Every appliance in our roundup supports AES-NI, so this is more about CPU generation than feature presence.

For gigabit internet with WireGuard or IPsec VPN, any quad-core Celeron or Atom from the last five years will keep up. For multi-gig fiber or OpenVPN-heavy workloads, look at the Intel N150, Atom C1110, or newer silicon. The Netgate 4200 MAX and Glovary N150 are the strongest performers in this regard.

Network Ports and 2.5GbE vs 1GbE

Port count matters more than people realize. A four-port firewall lets you run WAN, LAN, guest, and DMZ networks on dedicated interfaces. A two-port firewall forces VLAN tagging on a single LAN port, which works but adds complexity. If you have any plans for network segmentation, get a four-port or six-port appliance.

2.5GbE is increasingly relevant as ISPs roll out 2 Gbps and 2.5 Gbps service tiers. The Protectli FW4C, Glovary N150, VNOPN F12, and Netgate 4200 MAX all ship with 2.5GbE Intel i226 NICs. Realtek-based 2.5GbE implementations have notorious FreeBSD driver issues, so stick with Intel silicon. Older appliances like the Protectli FW4B and FW6A top out at gigabit, which is fine today but limits future upgrades.

RAM and Storage Sizing

For pfSense CE without packages, 4GB of RAM is plenty. For pfSense+ with Suricata, pfBlockerNG, and NtopNG, bump up to 8GB. For users running pfSense inside Proxmox with multiple VMs, 16GB or 32GB is the right starting point.

Storage is more forgiving. pfSense itself uses less than 2GB. The remaining space goes to logs and package data. A 32GB SSD handles basic logging for a year before you need log rotation. A 120GB SSD like the one in the Protectli FW4C gives you years of headroom. Avoid eMMC storage where possible, as the limited write endurance causes failures under heavy IDS logging.

Power Consumption and 24/7 Operation

A firewall runs 24/7, so power draw compounds. The VNOPN F12 at 6W idle costs roughly 5 dollars per year to operate. The Protectli FW6A at 35W costs roughly 30 dollars per year. Over a five-year deployment, that difference covers a new appliance.

For most home users, anything under 15W is excellent. Look at the rated power draw in the spec sheet and remember that pfSense idle draw is typically 60 to 70 percent of the rated maximum.

Pre-Configured vs Barebones

Pre-configured appliances like the Netgate 2100 and Netgate 4200 MAX ship with pfSense+ pre-installed. You plug them in, configure your WAN and LAN interfaces, and you are running. Pre-configured is the right choice for beginners who want the shortest path to a working firewall.

Barebones appliances like the Protectli FW4B and FW6A ship without RAM, storage, or OS. You bring your own components and install pfSense yourself. Barebones is cheaper and more flexible, but adds setup complexity. The Protectli FW4C and VNOPN F12 split the difference by including RAM and storage but not the OS.

Sizing Your pfSense Hardware by Internet Speed

One of the most common questions on r/PFSENSE is “what hardware do I need for my internet speed?” After testing eight appliances at different throughput levels, here is the sizing guide we built. Match your ISP speed to the appliance tier that can handle it with headroom.

Up to 300 Mbps: Budget Tier

If you have a 100 to 300 Mbps connection, the Protectli FW2B or VNOPN F12 will route traffic at line rate. You do not need 2.5GbE ports at this speed, so the older gigabit-only appliances are perfectly capable. Save your money for other network upgrades.

300 Mbps to 1 Gbps: Mainstream Tier

For gigabit internet, the Protectli FW4B, FW4C, or Netgate 2100 are the right picks. Quad-core CPUs and AES-NI acceleration ensure you can run WireGuard or IPsec VPNs without bottlenecking your connection. The FW4C’s 2.5GbE ports also future-proof you for a 2 Gbps upgrade.

1 Gbps to 2.5 Gbps: Multi-Gig Tier

For 2 Gbps or 2.5 Gbps service tiers, you need 2.5GbE ports and a CPU that can push more than gigabit. The Glovary N150, Protectli FW4C, VNOPN F12, and Netgate 4200 MAX all fit this tier. Choose based on whether you prioritize ports (Glovary N150), pre-configuration (Netgate 4200 MAX), or value (FW4C and VNOPN F12).

5 Gbps and Above: Performance Tier

For 5 Gbps or 10 Gbps fiber, the Netgate 4200 MAX is the only fanless appliance in our roundup that can handle that kind of bandwidth. At those speeds, even the Netgate 2100 becomes a bottleneck. If you need more than 10 Gbps, you are looking at rackmount hardware with active cooling, which is beyond the scope of this roundup.

pfSense CE vs pfSense+: Which Software Should You Run?

One of the most common points of confusion for new buyers is the difference between pfSense CE (Community Edition) and pfSense+ (the commercial version from Netgate). Both are based on the same FreeBSD codebase, but they diverge in important ways.

pfSense CE is the free, open-source version that you can install on any hardware. It receives security updates but has a slower release cadence. pfSense+ is what ships pre-installed on Netgate appliances and includes commercial features like auto-config backups, the pfSense+ cloud management portal, and priority security updates.

When to Choose pfSense CE

Choose pfSense CE if you are running pfSense on non-Netgate hardware (Protectli, Glovary, Qotom, or any white-box mini PC). It is free, fully featured, and works identically to pfSense+ for routing, firewalling, VPN, and VLANs. The only features you miss are cloud-based management and commercial support.

pfSense+ on non-Netgate hardware requires a paid subscription. As of 2026, a pfSense+ subscription for a single home or SOHO deployment costs around 129 dollars per year. For most home users, that is not worth it when pfSense CE delivers the same core functionality for free.

When to Choose pfSense+

Choose pfSense+ if you are running a Netgate 1100, 2100, 4200, or 6100 appliance, because the subscription is bundled with the hardware. You get commercial support, automatic updates, and the cloud management portal without paying extra.

For business deployments that need audit logs, compliance features, and priority support, pfSense+ is the right choice. For home labs and enthusiasts, pfSense CE is the smarter spend.

OPNsense as an Alternative

OPNsense is a fork of pfSense that has gained significant community traction. It uses a different web interface (based on FreeBSD with a PHP framework), has a more active development cadence, and includes features like built-in intrusion prevention and traffic shaping without additional packages.

Every appliance in our roundup runs OPNsense without issues. The Glovary N150 specifically markets OPNsense compatibility. If you are starting fresh and want to evaluate both, install each on a separate SD card or SSD and see which interface you prefer.

Frequently Asked Questions

Final Verdict: Which pfSense Firewall Should You Buy?

After three months of testing, our team landed on different recommendations based on user type. If you want a fanless pfSense firewall that just works out of the box with lifetime commercial support, the Netgate 2100 is the right pick. It ships pre-loaded with pfSense+ and has the backing of Netgate’s engineering team.

If you want the best balance of price, performance, and 2.5GbE future-proofing on third-party hardware, the Protectli Vault FW4C is our top choice. It runs pfSense or OPNsense without configuration headaches and has the port count to handle most home networks.

If you are on a strict budget and want a barebones box you can configure yourself, the Protectli Vault FW4B is the proven workhorse. For users who need six 2.5GbE ports for advanced network segmentation, the Glovary N150 is the standout. For multi-gig fiber at 5 Gbps and above, the Netgate 4200 MAX is the only fanless appliance that will not hold you back.

The pfSense ecosystem in 2026 is healthier than ever, with over 10 million deployments worldwide and a vibrant community on r/PFSENSE for troubleshooting. Whichever fanless appliance you choose from this roundup, you are getting a silent, reliable, low-power firewall that will outlast any consumer router. Pick the tier that matches your internet speed, confirm it has Intel NICs for FreeBSD compatibility, and enjoy enterprise-grade network security in a box smaller than a paperback book.
