The SG300 is a compact, feature-rich network security appliance that is perfect for securing very small networks and remote workers. The onboard 10/100 Ethernet switch enables a small business to implement a LAN quickly and easily, and connect the network to the Internet via broadband (ADSL, cable, SHDSL, etc.) or narrow-band (modem or ISDN) connections. If the broadband connection is lost, the SG300 can fail over in seconds to the narrowband connection, ensuring maximum uptime.
