The Juniper Networks Secure Services Gateway 500 Series (SSG) represents a new class of purpose-built security appliance that delivers a perfect mix of performance, security and LAN/WAN connectivity for regional and branch office deployments.

Complementing the powerful UTM security features is a robust routing engine that allows the SSG 500 Series to be deployed as a traditional branch office router or as a combination firewall and routing device to reduce capital and operational expenses.The SSG 500 Series are ideally suited for regional/branch offices, medium businesses and service providers that want a security platform to protect their WAN and high speed internal networks while extending the platform return on investment through high levels of system and interface modularity.The SSG 520M delivers 600 Mbps of IMIX firewall traffic and 300 Mbps of IPSec VPN. Connectivity options include four on-board 10/100/1000 interfaces and six I/O expansion slots for LAN and WAN flexibility.
