Description
Sophos SG330 — Next-Generation Firewall
The Sophos SG 330 is a powerful, enterprise-grade Security Appliance designed to meet the demanding requirements of growing mid-sized organizations. Combining advanced Intel multi-core technology, integrated SSD storage, and flexible hardware modularity, the SG 330 delivers superior protection against malware, unauthorized intrusions, and web threats without compromising network speed.
Hardware & Connectivity
Equipped out of the box with 8x GbE copper ports, 2x 1-GbE SFP ports, and 2x 10-GbE SFP+ ports, the SG 330 provides high-density fixed connectivity. Its integrated 1U FleXi Port expansion bay allows network administrators to effortlessly add additional copper, 1G fiber, or 10G fiber modules as infrastructure requirements evolve.
Why Choose Sophos SG 330?
With throughput capabilities up to 22 Gbps for stateful firewalling and 6 Gbps for Intrusion Prevention (IPS), the SG 330 ensures smooth data flow even under heavy traffic loads. Features like dynamic clustering up to 10 units, centralized management capabilities, and rich reporting tools make it a reliable cornerstone for modern security architectures.
Selection Guide
For Network Sizing
Evaluate network user count and bandwidth demands. The SG 330 is optimized for environments with 301 to 500 active users requiring high IPS and proxy scanning throughput.
For Transceiver Selection
Select 1G (ITFZTCHSX/LX) or 10G (ITFZTCHXF/LR) optical transceivers based on fiber distances and core switch interface speeds. Use copper SFP (ITFZTCHTC) when RJ45 connections are required in SFP slots.
For Port Expansion
Confirm port requirements and choose the compatible 1U FleXi Port module (copper, SFP, or SFP+) to populate the onboard expansion bay.
Always Verify
Verify hardware revision level (e.g., Rev. 2) and current UTM software licensing options prior to selecting expansion modules or ordering renewals.
Installation Notes
Mount the SG 330 into a standard 19-inch rack using the included rackmount ears and hardware. Connect power cables to the internal auto-ranging power supply (90-264V AC). Transceivers insert directly into the front SFP/SFP+ cages until securely clicked into place. FleXi Port modules must be inserted into the front expansion slot with the appliance powered off in accordance with official hardware guidelines.
Best Practices
Always mount the unit using proper rack rails or ears to keep airflow vents clear. Use official Sophos transceivers and certified FleXi Port modules to ensure full firmware compatibility. Maintain regular backup files of UTM configuration settings. Keep a hot-swappable spare transceiver on hand for critical uplink paths.

- Flexible scaling via modular FleXi Port expansion without complete appliance replacement
- Accelerated reporting and log search speeds powered by internal SSD storage
- High-availability clustering options to safeguard critical business continuity
- Reduced operational overhead through unified UTM management
