Visit firewall security for Belgian SMEs has become a business survival issue in 2026. Attacks specifically targeting small and medium-sized businesses have tripled in two years: 56 % of SMEs hit by ransomware in Belgium take more than a month to resume normal activity, and 23 % never recover. Yet, with a controlled cybersecurity budget and a correctly chosen firewall, an SME can achieve a level of protection equivalent to that of large corporations. At WEBIPHI, We support Belgian SMEs in this deployment, from Brussels.
Why firewall security is critical for Belgian SMEs
The myth persists: «we're too small to be targeted». The reality in 2026: 71 % of cyberattacks in Belgium target companies with fewer than 250 employees. For an automated attacker, your size doesn't matter - only ease of entry. The firewall is the tool that turns your SMB into an expensive target, thus abandoned by most opportunistic attackers.
What is a firewall for SMBs?
A firewall for SMBs is a device (physical appliance or cloud service) that inspects all traffic entering and leaving your network and blocks unauthorized connections. Unlike a consumer firewall, a pro firewall integrates antivirus, intrusion prevention, URL filtering, VPN and unified reporting. What we offer firewall and network security is designed for Belgian SMEs.
The 3 types of firewall for Belgian SMEs
Hardware firewall (NGFW / UTM)
A physical appliance installed between your Internet router and the internal network. Recommended models for SMEs: Fortinet FortiGate 40F/70G, Sophos XGS 116/126, Watchguard T25. Initial investment €1,500 to €4,000 + annual licenses €600 to €1,800. The best option for a single site with 5 to 50 users.
Cloud firewall (FWaaS / SASE)
No hardware, monthly subscription per user (€10 to €25/month). Ideal for telecommuting, multi-site or hybrid SMBs. Cloudflare One, Zscaler, Cato Networks. Rapid configuration and deployment, automatic updates.
Server-based software firewall
For very small budgets or environments with a single critical server. Less versatile than NGFW, but can be deployed quickly (pfSense, OPNsense, Sophos UTM Home for personal use). Recommended only as a complement to other protections.
Belgian specificities: NIS2, RGPD and bonuses
Since October 2024, the NIS2 requires a wide range of Belgian SMEs (healthcare, transport, finance, critical subcontractors) to have a documented firewall and disaster recovery plan. The RGPD imposes technical protections against exfiltration. Good news: the digitalization bonus in Belgium can finance up to 50 % of the cost of a cybersecurity project including the firewall, depending on the region (Brussels, Wallonia, Flanders).
Mistakes to avoid in SME firewall security
- Buy a mid-range box and leave it configured by default.
- Do not centralize logs or configure alerts.
- Forget about firmware updates for months.
- No recovery plan - see our guide disaster recovery plan.
- Rely solely on the firewall without reliable backup or team training.

FAQ - Firewall security for Belgian SMEs
Which firewall for a Belgian SME with 10 employees?
A Fortinet FortiGate 40F or Sophos XGS 116 perfectly covers the needs of up to 25 users: firewall, IPS, antivirus, VPN, reporting. Total cost over 3 years (hardware + licenses) between €3,000 and €5,000, including digitalization bonus potentially applicable.
Does the digitalization bonus finance the firewall?
Yes, in all three regions: Brussels via Hub.brussels, Wallonia via digital vouchers, Flanders via kmo-portefeuille. Firewall and associated licenses are eligible. See our guide digitalization bonus in Belgium.
Is my antivirus not enough?
No. The antivirus protects the machine, the firewall protects the network. The two are complementary. The majority of ransomware that paralyzes Belgian SMEs passes through channels that only a professional firewall can filter (exposed RDP, open ports, malicious encrypted traffic).
Do you need an in-house IT specialist to manage a firewall?
Not compulsory. The majority of Belgian SMEs outsource their firewall administration to an agency like WEBIPHI: a monthly fee, continuous supervision, automatic updates and rapid intervention in the event of an incident. It's more cost-effective and more reliable than junior in-house IT.
