Technical Details for Secure Computing Snapgear Security Appliance model SG560

Secure Computing Snapgear Security Appliance model SG560 ... also a great choice for cost-effectively protecting satellite offices, gas stations and restaurants, as well as SCADA installations. The SG560 enables remote office networks to easily connect their PCs and servers to the Internet via broadband (ADSL, cable, SHDSL, T-1 and T-2 circuits, etc.) or narrow-band (modem or ISDN). The SG560 provides connectivity and security features normally found in enterprise-class solutions. With the inclusion of five Fast Ethernet ports, link fail-over and Internet session load balancing as well as multiple security zones, the SG560 can be deployed in a myriad of environments.

Should the primary broadband connection fail, the SG560 can fail over to a second broadband link, ensuring uninterrupted service. Internet traffic can also be load balanced between links, increasing bandwidth for web surfing. And if there is a complete broadband failure, the SG560 can automatically restore Internet connectivity with a dial-up connections.

A powerful stateful-inspection firewall, service-based intrusion detection blocking and advanced Internet connection sharing protect the branch office network from the Internet. The SG560 provides three security zones (DMZ, Guest, and LAN) on separate Ethernet segments. These have appropriate default security policies. The DMZ segment can be used for publicly accessible servers (e-mail, file download etc.) the Guest segment enables mobile staff or visitors to have general Internet access only, while the LAN segment connects the entire office network. These security zones can be reconfigured as required. For example, if only one WAN connection is in use, the other can be configured as a fourth security zone.
