Compare Fortinet FortiGate, Sophos Firewall/XGS, SonicWall TZ, and Cisco Meraki MX as appliance-based candidates; consider a cloud firewall service only if you want a different operating model. No available evidence establishes one as the universal winner or supports a dependable current price ranking.
Which Firebox alternatives should a small business compare?
These are commercial firewall families to shortlist, not a ranked lab-test result. Their practical differences are largely about security-service needs, management preferences, network design, and licensing. FUSE’s August 2026 EU buying guide offers a reseller’s perspective on those differences; its characterizations are useful questions to investigate, not independent benchmark conclusions.
| Option | Why consider it | What to verify before choosing |
|---|---|---|
| Fortinet FortiGate | Fortinet offers a small-business firewall range. Its official Small Business Network Firewalls page directs buyers to consider bandwidth, users, devices, and security needs when selecting a product. | Confirm which currently available model meets your throughput requirement with the intended security services enabled. Get the full bundle, support, and management requirements in the quote. |
| Sophos Firewall / XGS | It is a candidate in SMB firewall comparisons. FUSE characterizes Sophos as a possible fit for businesses that value its management interface and Sophos Central integration. | Check how it fits any Sophos endpoint or management products you already use, and verify the target model’s performance with your chosen services, including TLS inspection if required. |
| SonicWall TZ | The TZ family appears in business-firewall comparisons and offers security-bundle choices to investigate. | For the exact model and contract, confirm included services, support, management options, renewal terms, and what functions remain if a security license expires. A third-party description of one family or plan is not a guarantee for every SKU. |
| Cisco Meraki MX | FUSE highlights Meraki’s dashboard-based management, Auto-VPN, and unified cloud management as potentially useful for multi-site or MSP-managed businesses. | Confirm the subscription needed for the intended features, renewal cost, and what happens if the subscription expires using current Cisco documentation for the exact product and region. |
| Cloud firewall service | Expert Insights presents NordLayer Cloud Firewall as a no-hardware option for small and midsize hybrid-cloud teams that do not have dedicated firewall expertise. | Establish whether the service covers your local network, site-to-site connections, performance, and regulatory requirements. It is a different operating model, not a like-for-like appliance replacement. |
FUSE describes FortiGate as strong on raw NGFW performance per euro and SD-WAN, Sophos on management UI and Central integration, and Meraki on dashboard and multi-site management. Treat those as the reseller’s comparative perspective. Expert Insights’ 2026 business-firewall comparison describes evaluating performance under security load, policy management, cloud integration, and deployment complexity; that does not establish a winner for your requirements.
How should you size a replacement firewall?
Size for the traffic the firewall must handle with the security services you intend to run—not just the vendor’s headline firewall throughput. Inspection features such as intrusion prevention, antivirus, application control, and TLS inspection can change the usable throughput for your workload. Check the current specification for the exact model and service set, and ask the vendor or integrator to confirm the match.

Estimate the throughput requirement
FUSE’s EU-focused guide, updated 22 August 2026, recommends using aggregate WAN bandwidth multiplied by 1.5 as a headroom rule of thumb, then selecting a model whose NGFW or threat-prevention throughput exceeds that figure with IPS, antivirus, application control, and TLS inspection enabled. This is reseller guidance, not a universal standard or a guarantee for a particular network.
For illustration, that guide gives a 1 Gbps fibre, 50-user office example and names FortiGate 80F, Sophos XGS 136, Meraki MX85, WatchGuard M290, and Kerio NG500 as examples to consider. These are examples from that guide, not a current equivalency list or recommendation. Model generations, availability, and specifications change; check current documentation before purchase.
Account for the rest of the network
- WAN and failover: Record required internet speed, the number of WAN connections, and whether failover is needed.
- Interfaces: List required port types and counts, including any needs for segmentation or connections to other network equipment.
- Remote and site-to-site VPN: Estimate simultaneous remote users and the number of office-to-office tunnels; confirm the proposed model and license support them.
- Security services: Specify which inspection, filtering, and protection services must run together, rather than comparing throughput figures with different services enabled.
- Management and support: Decide who will manage policies, updates, and monitoring, and what support response the business needs.
If an outage would cause meaningful revenue or productivity loss, FUSE says high availability may be appropriate. Its guide notes that an active-passive arrangement requires two appliances and an appropriate license. Ask an integrator to validate the failover design, licensing, and recovery requirements for your network.

How do you make the options comparable?
Ask vendors or resellers to quote the same workload, features, support level, region, and contract period. A low hardware quote can omit subscriptions or management capabilities required for the way you intend to use the firewall.

Subscription terms can affect both the long-term cost and the firewall’s security or management capabilities. Do not assume that products from the same vendor—or even different bundles for one model—have identical expiry behavior.
Rank #3
- INTEGRATED FIREWALL APPLIANCE AND SECURITY SERVICES: Comes with FortiGate-40F Firewall Appliance, 1 year of FortiCare Premium, and FortiGuard Unified Threat Protection.
- UTP SECURITY FEATURES: Offers protection from advanced threats with DNS filtering, URL filtering, video filtering, and controls against botnets.

- Ask which security, cloud-management, and support features are included in the quoted bundle and term.
- Request renewal pricing for the same services and contract period, rather than comparing only the first purchase.
- Get the effect of expiry in writing for the exact SKU and region. Universal Connectivity describes Meraki as requiring an active subscription and says Fortinet and SonicWall retain core firewall or routing functions after security-license expiry, but these are third-party descriptions. Verify current terms with the vendor for the specific model and contract.
- Confirm who will track renewal dates and what process keeps protection and management continuous.
These checks matter especially when comparing a subscription-led cloud-managed option with an appliance configured and supported under a different contract model.
Which option fits common small-business situations?
- You want a traditional appliance and broad secure-networking capabilities: Put FortiGate on the shortlist, then validate the specific model’s inspected throughput, bundle, and management needs.
- Your team already works with Sophos products: Assess Sophos Firewall/XGS for management fit and Central integration, while checking throughput with the intended inspection enabled.
- You need straightforward oversight across several sites: Evaluate Meraki MX’s dashboard and Auto-VPN capabilities against your subscription and multi-year cost requirements.
- You are considering a TZ appliance: Compare SonicWall’s exact services, management, support, and expiry terms with the other quotes rather than relying on a general description of the family.
- You prefer not to run an on-premises appliance: Investigate whether a cloud firewall service can protect the locations, connections, and workloads you actually have; first establish that its architecture meets your site-to-site and local-network needs.
Replacing a Firebox is also a chance to document existing WAN, VPN, security, and management requirements before requesting quotes. Include migration and configuration work if it is material to your changeover plan; no standard labor cost can be inferred from the available sources.
