The 13 tools, reviewed
#1 Sophos Firewall
Next-gen firewall managed from Sophos Central · United Kingdom · sophos.com
next-gen firewall UK vendor cloud managed
Sophos Firewall suits a company with one or two IT people who want inspection of encrypted traffic without hiring a firewall specialist. Xstream sends trusted flows down a fast path so deep inspection is spent on the traffic that needs it.
- Pricing: Quote only. Hardware or virtual appliance plus subscription bundles (Xstream Protection, Xstream Plus); prices go through partners. Free plan: free trial.
- Best for: Small teams already using Sophos endpoint
- Strengths: Xstream FastPath acceleration; TLS inspection; SD-WAN orchestration.
Where it falls short
There is no public price list, so comparing against rivals means collecting partner quotes. Some of the best features, such as ZTNA and the central console, only pay off when the rest of the estate is Sophos too.
Wrong for
A global enterprise with tens of thousands of users and a dedicated network security team should look at Palo Alto Networks or Fortinet.

#2 OPNsense
Open source firewall and routing platform on FreeBSD · Netherlands · opnsense.org
open source FreeBSD Dutch vendor
OPNsense gives a small network the features that commercial boxes lock behind licenses, with source code anyone can read. The two-clause license and a project that releases on a steady schedule keep the product easy to audit. Intrusion detection runs on open rule sets, with the commercial ET PRO feed as an option you choose rather than a requirement.
- Pricing: Open source + paid tiers. The software is free to download under a two-clause BSD license. Free plan: open source.
- Best for: IT generalists who want open source
- Strengths: Stateful firewall; WireGuard and IPsec VPN; Suricata intrusion detection.
Where it falls short
Support depends on forums and the paid subscriptions, not a global partner channel. Central management of many sites is a plugin, not a mature console.
Wrong for
A company that needs a vendor to own every outage, with certified engineers on every continent, should buy Cisco or Fortinet.

#3 WatchGuard Firebox
Firebox appliances managed from WatchGuard Cloud · United States · watchguard.com
UTM appliance MSP friendly tabletop and rackmount
WatchGuard builds for the buyer whose firewall is looked after by a reseller. The T Series covers offices, branches and retail sites, the rackmount M Series covers heavier VPN and UTM loads, and virtual and cloud editions follow the same security model into AWS and Azure.
- Pricing: Quote only. Appliance plus a security suite subscription; the site routes price questions to a Get Pricing form and a partner. Free plan: free trial.
- Best for: Small firms served by an MSP
- Strengths: Firebox T Series; Firebox M Series; FireboxV.
Where it falls short
Prices are hidden behind a form, so a direct internet purchase comparison is hard. Deep policy tuning and scripting trail Palo Alto and Fortinet. The company is American, with the usual question about support location.
Wrong for
A security team that wants to write detailed application policy or automate through every API should use Palo Alto Networks.

#4 Fortinet FortiGate
Firewalls on FortiOS with in-house security chips · United States · fortinet.com
FortiOS custom ASIC secure SD-WAN
FortiGate matters because it shrinks the gap between a branch router and a data-center firewall into one product family. Fortinet describes custom ASICs as the way throughput per rack unit stays high while power drops, and the same FortiOS runs from a FortiGate 30G at the small end to the 7121F at the top. SD-WAN is a built-in feature, not an add-on.
- Pricing: Quote only. Hardware sold through resellers with FortiGuard subscription bundles. Free plan: none.
- Best for: Cost-conscious networks needing throughput
- Strengths: FortiOS; FortiASIC security processors; Secure SD-WAN.
Where it falls short
The broad feature set means a lot of licensing options to untangle, and the interface rewards experience. Patch discipline is a real running cost for any edge device. Smaller buyers can find the lineup bewildering.
Wrong for
A five-person office with one site and no network staff will find the platform heavier than it needs.

#5 Palo Alto Networks Next-Generation Firewall
Application-aware firewalls from PA-Series to cloud · United States · paloaltonetworks.com
App-ID Panorama enterprise NGFW
Palo Alto Networks sets the pattern others copy. App-ID classifies traffic by application on any port, User-ID ties rules to people, and decryption lets the policy see inside TLS. Panorama or Strata Cloud Manager keeps hundreds of devices consistent.
- Pricing: Quote only. Hardware, virtual and container firewalls with subscription services such as Advanced Threat Prevention; the product page lists no prices. Free plan: none.
- Best for: Enterprises with security operations staff
- Strengths: App-ID; User-ID; PA-Series hardware.
Where it falls short
Subscriptions stack up quickly, and each cloud-delivered service is a separate line item. The learning curve is steep and a policy cleanup project is common after an inherited deployment. Small offices pay for headroom they will never use.
Wrong for
A company of fifty people with one part-time administrator should look at Sophos or WatchGuard.

#6 Stormshield Network Security
European firewalls with state-certified firmware · France · stormshield.com
French vendor CC EAL4+ IT and OT
Stormshield's argument is provenance. Its firmware carries a Common Criteria EAL4+ certification from the French agency ANSSI and approvals from Spain's CCN, which procurement offices in those sectors can cite directly. The product line spans IT and industrial networks, and the page quotes throughput up to 319 Gbps for the largest models.
- Pricing: Quote only. Hardware and virtual appliances sold through partners; the product page publishes no prices. Free plan: none.
- Best for: Regulated European and public-sector sites
- Strengths: SNS firewalls; CC EAL4+ certified firmware; Intrusion prevention.
Where it falls short
The partner network and community knowledge are smaller than those of the US giants, so staff with prior experience are harder to hire. No public prices make early budgeting slower. Cloud-native and container coverage is thinner.
Wrong for
A startup running mostly in public cloud should look at the cloud firewalls of Palo Alto Networks or Fortinet.

#7 pfSense
Open source firewall with commercial Netgate Plus · United States · pfsense.com
open source Netgate FreeBSD
pfSense has the clearest price story in this list. Netgate states that its software pricing carries no throughput, seat or connection tack-ons, and prints a starting price for appliances and an hourly rate for cloud images. A small company can run the free edition on spare hardware or buy a ready box with support tiers.
- Pricing: Open source + paid tiers. Community Edition is free. Free plan: open source.
- Best for: Technical teams, labs and small offices
- Strengths: Stateful firewall; VPN; Routing.
Where it falls short
The split between Community Edition and Plus confuses buyers, and the web interface looks dated next to newer rivals. Central management for fleets is limited. Advanced threat services are less integrated than those from the larger suites.
Wrong for
A company that wants a cloud console, zero-touch shipping and a security subscription managed for it should buy Sophos or WatchGuard.
Visit pfSense →
#8 Check Point Quantum
Quantum firewalls with a single management portal · Israel · checkpoint.com
Quantum Force Maestro subscription hardware
Check Point is the veteran of the category, and its current lineup covers every size. The page lists data center models up to 75 Gbps of threat prevention, perimeter boxes at 25, branch at 7, and Maestro clusters scaling to 1,000 Gbps. A single portal manages hardware, virtual and cloud gateways.
- Pricing: Quote only. A Firewall-as-a-Subscription option bills hardware, threat prevention and cloud management monthly or annually; no figures are published on the product page. Free plan: none.
- Best for: Mixed estates wanting hardware as a subscription
- Strengths: Quantum Force appliances; Maestro clustering; SMB firewalls.
Where it falls short
Pricing detail requires a conversation and a reseller, and no figure appears on the product page. The management concepts, with policy layers and a separate console, take time to learn.
Wrong for
A tiny office wanting a plug-in box should choose WatchGuard or Zyxel.
Visit Check Point Quantum →
#9 Zyxel Firewalls
Small-business firewalls with Nebula cloud management · Taiwan · zyxel.com
Nebula cloud small business Taiwan
Zyxel is the pragmatic pick for retail chains, clinics and branch offices that want one cloud view over firewall, switching and Wi-Fi. Nebula supports plug-and-play provisioning, so a box shipped to a site can be adopted without an engineer. The company separates security licenses from management licenses, which lets a buyer pay only for what each site needs.
- Pricing: Per device / license. Hardware plus separate licenses for security, management and reporting, described by Zyxel as flexible; no prices on the overview page. Free plan: free trial.
- Best for: Multi-site shops with limited budgets
- Strengths: NGFW appliances; Security routers; Nebula Cloud Center.
Where it falls short
Throughput under deep inspection is lower than at larger vendors, and advanced policy options are narrower. Analyst and partner mindshare in the United States and Europe is smaller. License bookkeeping per device adds admin time.
Wrong for
A company with an internal security team and a data center should look at Fortinet or Palo Alto Networks.

#10 SonicWall Firewalls
TZ, NSa and NSsp next-gen firewalls · United States · sonicwall.com
TZ series channel partners managed firewall
SonicWall covers branch to data center in four lines, from the TZ80 aimed at micro-SMBs to NSsp for service providers. Capture cloud sandboxing checks unknown files before delivery, and a managed service run by its SonicSentry team handles monitoring, tuning and firmware on newer generation boxes. An embedded cyber warranty through Cysurance is stated for qualifying deployments.
- Pricing: Quote only. Appliance with bundled security services; the product page lists no prices and mentions upgrade promotions. Free plan: none.
- Best for: SMBs buying through resellers
- Strengths: TZ Series; NSa Series; NSsp Series.
Where it falls short
Remote-access features on edge firewalls are a frequent attack target, so timely firmware updates are mandatory here as elsewhere. Pricing is not published on the product page.
Wrong for
A buyer who cannot guarantee quick patching should avoid exposing any firewall management port and look at Sophos with cloud updates.

#11 Cisco Secure Firewall
Cisco firewalls from branch to AI data center · United States · cisco.com
Cisco SnortML data center
Cisco makes sense when the switches, wireless and identity systems are already Cisco. The range goes from the 200 Series for small branches to the 6100 for large data centers, and the ISA3000 covers rugged industrial sites. SnortML blocks traffic patterns linked to zero-day attacks without waiting for hand-written signatures.
- Pricing: Quote only. Hardware with subscriptions; no prices on the product page, which instead offers a calculator for moving management to Cisco Cloud Control. Free plan: none.
- Best for: Cisco-centric networks and large enterprises
- Strengths: 200 Series; 1200 Series; 3100 Series.
Where it falls short
Management is split between the on-premises Firewall Management Center and a newer cloud control plane, which complicates migrations. Licensing is layered across hardware, threat and management subscriptions. Small companies often find it expensive for the features they use.
Wrong for
A small business without a Cisco network should look at WatchGuard or Sophos.

#12 Barracuda CloudGen Firewall
Firewall with built-in SD-WAN and cloud templates · United States · barracuda.com
SD-WAN cloud deployment Barracuda
CloudGen Firewall earns a place for companies with many small locations and a presence in several clouds. SD-WAN comes with the box, so connecting sites and clouds does not need a second product. Zero-touch deployment and API templates let a remote site be brought online without a technician.
- Pricing: Quote only. Appliance and cloud editions; the page splits navigation by fewer than 50 users or more, with a try-free option, and states no prices. Free plan: free trial.
- Best for: Distributed sites and Azure or AWS workloads
- Strengths: Built-in SD-WAN; Advanced Threat Protection sandbox; Firewall Control Center.
Where it falls short
It has less market momentum than the main enterprise names, so third-party training and engineer availability are limited in many regions. Prices are not public on the product page.
Wrong for
A single-site office should look at a simpler Zyxel or WatchGuard box.
Visit Barracuda CloudGen Firewall →
#13 Forcepoint NGFW
High-throughput firewalls managed from one console · United States · forcepoint.com
Forcepoint SMC high throughput
Forcepoint NGFW is built for the big site. The 3500 Series lists up to 66 interfaces and firewall throughput up to 600 Gbps, and the mid-range 1200 to 2300 models serve large offices. The Secure Management Console unifies policy, incident response and reporting for deployments anywhere in the world. The company says over twelve thousand customers use it.
- Pricing: Quote only. Sold through partners by model and subscription; the product page publishes no prices. Free plan: none.
- Best for: Large networks wanting central policy
- Strengths: 3500 Series; 3400 Series; 2300 Series.
Where it falls short
Small and mid-size options are thin and community knowledge is limited. No prices are published on the product page.
Wrong for
A small business needs a simpler box such as WatchGuard.

Questions and answers
What is the best network firewall software in 2026?
Sophos Firewall ranks first of 13, best for small teams already using Sophos endpoint. OPNsense is second (iT generalists who want open source) and WatchGuard Firebox third (small firms served by an MSP). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Is OPNsense or pfSense the better free firewall?
Both are capable and both run on ordinary hardware.
Do I need a next-generation firewall for a small office?
If the office runs only a handful of cloud applications, a good router with a default-deny policy covers many risks.
How much do firewall subscriptions add to the hardware price?
Most vendors sell the appliance with a bundle of services such as intrusion prevention, sandboxing and web filtering, and the bundle often costs more than the box over several years.
Can I run a firewall in a cloud account instead of buying hardware?
Yes. Netgate sells pfSense Plus images in the AWS and Azure marketplaces from $0.08 per hour, WatchGuard offers Firebox Cloud, Barracuda provides templates for Azure, AWS and GCP, and Palo Alto Networks offers a managed Cloud NGFW for AWS.
Which firewall vendors are European?
Stormshield is French and carries ANSSI certification on its firmware. Deciso, the company behind OPNsense, is Dutch. Sophos is headquartered in the United Kingdom. Check Point is Israeli, Zyxel is Taiwanese, and the others here are American.
Should I manage the firewall from a cloud console?
A cloud console helps when you have several sites, little onsite staff or an MSP, since policy and reports are reachable anywhere and new boxes can be provisioned remotely.
How often do firewalls need firmware updates?
Plan for monthly review and urgent patching within days of a critical advisory.
Is Palo Alto Networks worth it for a mid-sized company?
It can be if you have staff who will use App-ID, User-ID and Panorama, and if traffic visibility drives your risk work.
Can one firewall also handle SD-WAN and VPN?
Most current products can. Fortinet builds secure SD-WAN into FortiOS, Sophos offers orchestration with failover between links, Barracuda includes it in CloudGen, and OPNsense and pfSense handle WireGuard and IPsec tunnels with multiple gateways.
How do I migrate from one firewall vendor to another?
Expect a rebuild, not a file conversion. Export the old configuration, list every object and rule with its owner, and delete rules nobody can explain.
