The NetScreen-500 is a purpose-built, security system designed to provide a flexible, high performance solution for medium and large enterprise central sites and service providers. The NetScreen-500 security system integrates firewall, DoS, VPN and traffic management functionality in a low-profile, modular chassis. It provides high levels of total throughput for firewall and VPN plus support for virtual systems and security zones. Combined with a flexible and resilient hardware architecture incorporating modular physical interfaces, redundant power supplies, fans and high availability interfaces, the NetScreen-500 exceeds most enterprises’ typical traffic conditions. It is well suited to match the peak load and strong deterrence requirements of the most demanding environments.

The NetScreen-500 GPRS system combines the hardware-accelerated firewall, VPN, and traffic management capabilities of the NetScreen-500 with enhanced features designed to provide mobile operators with a purpose-built, high-performance, and scalable security solution for protecting GPRS data networks. The NetScreen-500 GPRS solution secures roaming connections using a combination of Stateful inspection, traffic rate limiting, traffic sanity checks, traffic logging, and traffic accounting. These features allow mobile operators to protect their network infrastructure from Denial of Service (DoS) attacks and subscriber hijacking attacks. The NetScreen-500 GPRS features can also be used to control roaming partner network access, in addition to controlling which external networks subscribers may access (through APN filtering). GTP Releases 1997 and 1999 are both fully supported, including charging gateway traffic. The NetScreen-500 GPRS system provides secure, scalable Internet and corporate intranet connectivity from a mobile operator's network.
