Security Capabilities
The SG 115w was designed as a security gateway supporting firewall, VPN, IPS, and antivirus proxy workloads. Its published performance specifications provide a basis for evaluating the appliance against network requirements.
For deployments using legacy SG hardware, organizations should verify the applicable Sophos software, licensing, support, and lifecycle requirements before procurement or deployment.
Selection Guide
For Branch Offices
Consider the Sophos SG 115w when you need a compact security appliance with integrated wireless capabilities and Gigabit Ethernet connectivity.
For Wireless Deployments
Choose the SG 115w rather than the non-wireless SG 115 when integrated wireless functionality is part of the deployment requirement.
For Security Throughput
Review expected firewall, VPN, IPS, and antivirus proxy traffic against the published appliance throughput figures.
The published Rev. 2 figures are:
- Firewall: up to 2.3 Gbps
- VPN: up to 425 Mbps
- IPS: up to 500 Mbps
- AV Proxy: up to 120 Mbps
For Physical Deployment
The SG 115w is a desktop appliance. Where rack installation is required, verify availability and compatibility of the appropriate Sophos rackmount accessory before purchasing.
Always Verify
Confirm the exact hardware revision, Sophos software compatibility, licensing requirements, wireless requirements, and current lifecycle status before ordering.
Sophos has published an SG-to-XGS migration path that maps the SG 115(w) to the XGS 118(w), which is relevant when evaluating an existing SG deployment or a replacement strategy.
Installation Notes
The Sophos SG 115w is designed as a desktop appliance. Place the unit on a stable surface with sufficient airflow around the appliance.
Connect the required Ethernet interfaces to the appropriate WAN and LAN infrastructure, connect the power supply, and follow the applicable Sophos installation and configuration documentation.
For wireless operation, configure the wireless functionality according to the applicable Sophos UTM documentation and local regulatory requirements. Sophos documentation notes that country settings regulate available wireless channels to comply with local law.
Before deployment, verify that the hardware revision and software version being used are supported for the intended installation.
Best Practices
- Verify the exact SG 115w hardware revision before purchase.
- Confirm software and licensing compatibility before deployment.
- Maintain adequate airflow around the desktop appliance.
- Use appropriate network cabling for Gigabit Ethernet connections.
- Configure wireless channels according to local regulatory requirements.
- Document WAN, LAN, and wireless configuration.
- Keep current configuration backups.
- Verify Sophos lifecycle and support information for legacy SG hardware.
- Consider the appropriate XGS replacement path for new deployments where applicable.
