Buying Guide
Performance And Throughput Considerations
For small businesses, throughput matters as user count and remote access grow. Look for IPS throughput when evaluating security performance, not just firewall rules. Appliances like FortiGate-40F advertise up to 1 Gbps IPS throughput with SSL traffic protection, while Zyxel USGFLEX100 highlights several measured figures (900 Mbps SPI, 360 Mbps UTM, 270 Mbps VPN). If you anticipate heavy VPN use or SSL inspection, lean toward models with higher IPS and VPN figures and consider hardware acceleration features.
Security Services And Features
Consider the breadth of integrated services: firewall, anti-malware, intrusion prevention, web filtering, application control, and botnet protection. Fortinet options emphasize Unified Threat Protection and Security Fabric integration, which can simplify management across multiple sites. If you need robust cloud-based management or Nebula/cloud options, Zyxel’s Nebula compatibility may be advantageous. SD-WAN capabilities can also reduce costs by routing traffic efficiently between offices and the internet.
Connectivity And Expandability
Small offices vary in their connectivity needs. Five-port models like the FortiGate-40F provide essential WAN and internal ports, while options with 10 GbE and 2.5 GbE interfaces offer headroom for growing networks and faster inter-device links. If you expect rapid growth or high local traffic, prioritize devices with multiple 10 GbE or 2.5 GbE options and consider expansion through modular or PCIe capabilities if available.
Deployment And Management
Universal management ease can save IT teams time. Look for devices with intuitive dashboards, centralized policies, and cloud-based management when appropriate. For distributed sites, cloud-visibility and simple provisioning are valuable. Open-source-friendly units (like the CWWK N100) allow customization but require more hands-on management, while polished vendor solutions offer more out-of-the-box security and support.
Hardware Form Factor And Noise
For office environments, a compact, fanless form factor reduces noise and saves space. The FortiGate-40F’s fanless design and small footprint are examples, as are other compact appliances. Evaluate whether your equipment sits in a shared workspace or dedicated IT closet and select a model that remains quiet under load while meeting performance targets.
Budget, Licensing, And Total Cost Of Ownership
Pricing and licensing vary. Some appliances come with included security services for a set term, while others are appliance-only with separate subscription costs for advanced protections. When planning, consider the total cost of ownership over multiple years, including potential VPN licenses, threat protection suites, and cloud management subscriptions. A straightforward, appliance-only option may suit lean budgets, while a scalable solution with ongoing services can reduce administrative overhead over time.
