ISG Series Integrated Security Gateways
The Juniper Networks Integrated Security Gateways (ISG) are ideally suited for securing enterprise, carrier and data center environments where advanced applications such as VoIP and streaming media dictate consistent, scalable performance. The Juniper Networks ISG 1000 and ISG 2000 are purpose-built security solutions that leverage a fourth generation security ASIC, the GigaScreen3, along with high speed microprocessors to deliver unmatched firewall and VPN performance. Integrating best-in-class firewall, VPN and DoS solutions, the ISG 1000 and ISG 2000 enable secure, reliable connectivity along with network and application-level protection for critical, high traffic network segments.
The ISG Series can be easily upgraded to support integrated Intrusion Detection and Prevention (IDP), providing robust network and application layer protection against current and emerging threats. Leveraging the same award-winning software found on Juniper Networks’ IDP platforms -but integrated into ScreenOS - the ISG Series provides a combination of best in class firewall, VPN, and IDP with dedicated processing modules that ensure multi-gigabit capability in a single solution. With unmatched security and network segmentation features, the ISG Series can be deployed to protect both perimeter deployments as well as internal networks.
ISG1000 Integrated Security Gateway
The ISG1000 is a fully integrated FW/VPN/IDP system with multi-gigabit performance, a modular architecture and rich virtualization capabilities, delivering up to 2 Gbps of firewall throughput and up to 1 Gbps of optional integrated IDP throughput. The base FW/VPN system comes with four fixed 10/100/1000 interfaces and two additional I/O modules for interface expansion.
ISG2000 Integrated Security Gateway 
The ISG2000 is a fully integrated FW/VPN/IDP system with multi-gigabit performance, a modular architecture, and rich virtualization capabilities, delivering up to 4 Gbps of firewall throughput and up to 2 Gbps of optional integrated IDP throughput. The base FW/VPN system allows for up to four I/O modules and three security modules for IDP integration.
