The Juniper Networks Secure Services Gateway 20 (SSG 20) is purpose-built security appliance that delivers a perfect blend of performance, security and LAN/WAN connectivity for small branch office and small business deployments. Traffic flowing in and out of the branch office can be protected from worms, Spyware, Trojans, and malware by a complete set of Universal Threat Management (UTM) security features including Stateful firewall, IPSec VPN, IPS, Antivirus (includes Anti-Spyware, Anti-Adware, Anti-Phishing), Anti-Spam, and Web Filtering.The rich set of UTM security features allows the SSG 20 to be deployed as a stand alone network protection device. With its robust routing engine, the SSG 20 can also be deployed as a traditional branch office router or as a combination security and routing device to help reduce IT capital and operational expenditures.This model is bundled with the Juniper Networks 1xADSL2+ Mini-Physical Interface Module that supports Annex B (over ISDN).
