JUNIPER NETWORKS ENTERPRISE SECURITY APPLIANCE PRODUCT LINE OVERVIEW

The Juniper Networks Integrated Security Gateways (ISG) are purpose-built, security solutions built around the fourth generation security ASIC, the GigScreen3, along with high-speed microprocessors to deliver unmatched firewall and VPN performance. These appliances are ideally suited for securing enterprise, carrier and data centre environments where advanced applications such as VoIP and streaming media dictate consistent, scalable performance. The ISG series can be upgraded to support integrated Intrusion Detection and Prevention (IDP) to provide robust network and application layer protection against current and emerging threats.

The NetScreen 5000 series is a line of purpose-built network security appliances that combine firewall, Virtual Private Networking (VPN), and traffic management functions designed to deliver high performance capabilities for large enterprise, carrier, and data center networks. Built around Juniper's third-generation security ASIC and distributed system architecture, the NetScreen-5000 series offers excellent scalability and flexibility.

JUNIPER NETWORKS GIGASCREEN ASIC

The GigaScreen security ASIC accelerates the firewall policy lookups and encryption and authentication algorithms in hardware. This is a significantly faster approach than a software only approach that relies solely on the CPU. This security-accelerating ASIC is tightly integrated with Juniper Network' s ScreenOS operating system to eliminate unnecessary software layers and security holes found in other security products built on general-purpose commercial operating systems.

RELIABILITY AND SECURITY OF APPLIANCES

The ease of installation and robust manageability of Juniper Network's all-in-one security appliances is complimented by its superior reliability and security capability. Without the inherent reliability issues associated with hard disk drives, appliances have proven to be the best long-term answer when uptime is important, offering high availability solutions with sub-second fail-over to maintain business continuity. Juniper Network's appliances only require configuration and management of the firewall, VPN, and traffic management features, alleviating the need to configure separate hardware and complex operating systems. This limits the time required to install and maintain the security device and reduces the number of setup steps where security holes are often created.
