These firewalls provide businesses with the assurance of a dedicated network security solution, with integrated functions including firewall, load balance, fault tolerance, ZoneDefense,
content filtering, user authentication, instant message and peer-to-peer application blocking, Denial of Service (DoS) protection and Virtual Private Network (VPN) secure remote connection.
Within an industrial chassis, D-Link NetDefend firewalls pack up an impressive set of hardware that includes high-speed processors, large databases and firewall power to handle up to a million concurrent sessions. These firewalls come with multiple user-configurable
interfaces, including high-speed Gigabit ports, for flexible, scalable and bottleneck-free network deployments linking your different workgroups and enterprises together.
D-Link NetDefend firewalls adopt a unique IPS technology - component-based signatures, which are built to recognize and protect against all varieties of known and unknown attacks, and which can address all critical aspects of an attack or potential attack including payload,
NOP sled, infection, and exploits. In terms of signature coverage, the IPS database includes attack information and data from a global attack sensor-grid and exploits collected from public sites such as the National Vulnerability Database and Bugtrax.
These firewalls deliver high quality IPS signatures by constantly creating and optimizing NetDefend signatures via the D-Link Auto-Signature Sensor System. Without overloading existing security appliances, these signatures ensure a high ratio of detection accuracy and the lowest ratio of false positives.
To minimize any impact of a disaster on an entire network, D-Link NetDefend firewalls 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 the network with malicious traffic.
D-Link NetDefend firewalls can be remotely managed via a web-based interface or through a dedicated VPN connection. They include flexible features to monitor and maintain a healthy and secure network, such as e-mail alerts, system log and real-time statistics. |
