Description
Sophos SG135W — Next-Generation Firewall
The Sophos SG 135w is a wireless network security appliance from the Sophos SG Series, combining firewall security, VPN connectivity, intrusion prevention, antivirus proxy processing, and integrated wireless networking in a desktop platform.
With up to 6 Gbps firewall throughput, 1 Gbps VPN throughput, and 1.5 Gbps IPS throughput, the appliance is designed for environments requiring significant security-processing capacity from a compact appliance.
Wireless Connectivity
The SG 135w includes integrated 802.11a/b/g/n/ac wireless connectivity with support for the 2.4 GHz and 5 GHz bands. It uses three external antennas and 3 x 3:3 MIMO capabilities for its integrated wireless interface.
Network Connectivity
The appliance provides eight fixed Gigabit Ethernet copper interfaces for wired network connections. Depending on the hardware revision, optional connectivity modules can further extend the deployment possibilities.
Optional Expansion
Compatible SG 135w Rev. 3 platforms can support a 3G/4G module, DSL modem through SFP, and a second Wi-Fi radio module. The second Wi-Fi radio module supports 802.11a/b/g/n/ac, 2 x 2 MIMO, and 2.4 GHz or 5 GHz operation.
Physical Deployment
The SG 135w uses a compact desktop chassis and can also be integrated into a rack using a separately available rackmount kit. This gives organizations flexibility when moving between desktop and structured rack deployments.
Selection Guide
For Wireless Firewall Deployment
Choose the SG 135w when integrated wireless networking is required together with firewall, VPN, IPS, and wired network connectivity.
For High Traffic Requirements
Review the documented throughput specifications and compare them with expected firewall, VPN, IPS, and application traffic before selecting the appliance.
For Additional Connectivity
Check the exact hardware revision before selecting optional 3G/4G, DSL, or second Wi-Fi modules. Sophos documentation identifies these options as revision-specific.
For Rack Installation
If the appliance needs to be installed in a standard rack, select the appropriate rackmount kit designed for the relevant SG Series hardware revision.
Always Verify
Cross-check the exact SG 135w model and hardware revision against current Sophos documentation before purchasing optional modules, rackmount hardware, or replacement accessories.
Installation Notes
Place the SG 135w on a stable surface with adequate ventilation and connect the required Ethernet, power, and wireless components according to the applicable Sophos installation documentation.
For wireless operation, install and position the external antennas correctly and configure the wireless network according to the deployment requirements.
If installing an optional expansion module, follow the hardware installation instructions for the exact SG 135w revision. Sophos documentation identifies optional modules such as 3G/4G and the second Wi-Fi radio as revision-specific components.
For rack deployment, use the compatible rackmount kit rather than a generic mounting solution.
Best Practices
Use the exact Sophos documentation for the appliance revision when installing or expanding the SG 135w.
Position the wireless antennas appropriately for the required coverage area.
Maintain adequate airflow around the appliance and avoid blocking ventilation openings.
Use compatible SFP transceivers and optional modules listed for the specific hardware revision.
Document network interfaces, wireless configuration, and installed expansion modules.
Keep firmware and security configurations aligned with the supported Sophos platform requirements.
Before purchasing replacement or expansion hardware, confirm model and revision compatibility.
