To minimize any impact of a disaster on an entire network, DFL-2500 include a special feature called ZoneDefense -- a mechanism that operates seamlessly with D-Link xStack switches to perform proactive network security. ZoneDefense automatically quarantines infected computers on the network and prevents them from flooding your network with malicious traffic. Within an industrial chassis, DFL-2500 pack up an impressive set of hardware that includes high-speed processors, large databases and firewall power to handle up to 1 million concurrent sessions. The DFL-2500 comes with multiple user-configurable interfaces, including high-speed Gigabit ports for flexible, scalable and cost effective network deployments linking the medium sized business or workgroup together. The DFL-2500 can be remotely managed via a web-based interface or through a dedicated VPN connection. It also includes flexible features to monitor and maintain a healthy and secure network, such as e-mail alerts, system log and real-time statistics. These features, along with the ability for firmware upgrade, ensure that your firewall can provide and maintain maximum performance and security for your network.
