How to choose a firewall for your business in 2026

Many business owners believe the standard router from their internet provider is enough to protect their company. In reality, that router offers minimal protection. A dedicated firewall is the first line of defence against cyberattacks — and SMEs are now targeted just as often as large corporations.

What a modern firewall actually does

A next-generation firewall (NGFW) doesn't just block ports. It inspects traffic in depth, identifies applications, blocks dangerous sites and stops attacks before they reach your workstations.

• Web filtering and application control
• Anti-malware and anti-ransomware protection at network level
• VPN for secure remote access
• Network segmentation (separating front desks from servers)
• Real-time reports and alerts

How big does it need to be?

Correct sizing is essential. An undersized firewall becomes a bottleneck that slows your internet, while an oversized one is wasted money. We choose the model based on the number of users, connection speed and the services you run.

Fortinet, Cisco or pfSense?

There's no universal answer. For small and medium companies, FortiGate offers the best feature/price ratio and simple management. pfSense is an excellent open-source solution for tight budgets but requires more expertise. Cisco remains the standard in complex enterprise environments. We help you choose based on real need, not commission.

Conclusion

A correctly chosen and professionally configured firewall makes the difference between a protected company and a vulnerable one. If you want an assessment of your current security, we'll run an audit and give you a clear recommendation. No jargon, no hard sell.
