The SSG 140 is a high-performance security platform for branch offices and small/medium sized standalone businesses that want to stop internal and external attacks, prevent unauthorized access, and achieve regulatory compliance. The SSG 140 is a modular platform that delivers more than 350 Mbps of stateful firewall traffic and 100 Mbps of IPSec VPN traffic. The SSG 140 supports ten on-board interfaces (8 10/100 plus 2 10/100/1000) complemented by four I/O expansion slots that can house additional WAN interfaces (T1, E1, ISDN BRI S/T and Serial), making the SSG 140 the most extensible security platform in its class. This broad array of I/O options coupled with WAN protocol and encapsulation support in its routing engine make the SSG 140 a platform that can easily be deployed as a traditional branch office router or as a consolidated security and routing device to reduce CAPEX and OPEX.
