Choosing a Firewall for a Small Business

Firewalls have changed. The box that ships with your internet service is a router with basic filtering. A modern business firewall, sometimes called a next-generation firewall or NGFW, does much more. It inspects encrypted traffic, blocks known malicious destinations, enforces application policies, and gives you visibility into what is actually happening on your network.

For a small business, the choice usually comes down to a few questions. How many users and devices are on the network. Whether you have remote workers who need secure access. Whether you need to segment guests, IoT devices, or point-of-sale systems. Whether compliance or cyber insurance requires specific controls.

What to look for in a small business firewall:

• Throughput that matches your internet speed with security services enabled, not just the marketing number.
• Active subscription services for intrusion prevention, content filtering, and anti-malware. The hardware without the subscriptions is a much weaker product.
• TLS or SSL inspection support, since most malicious traffic is now encrypted.
• Site-to-site and client VPN capabilities for remote users and multiple locations.
• VLAN support so you can separate guest Wi-Fi, IoT devices, and business systems.
• Centralized logging and alerts you will actually review, or a managed service that does it for you.
• A clear firmware and patch cadence from the vendor, with a track record of fixing vulnerabilities quickly.

Under-sizing is the most common mistake. A firewall rated for your peak traffic without security services enabled will slow to a crawl once you turn on the features that justified buying it.
