Robust Intrusion Prevention10
The NetDefend UTM Firewalls employ component-based signatures, a unique IPS
technology which recognizes and protects against all varieties of known and unknown
attacks. This system can address all critical aspects of an attack or potential attack including
payload, NOP sled, infection, and exploits. 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. The NetDefend UTM Firewalls constantly
create and optimize 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 a low ratio of false positives.
Stream-based Virus Scanning10
The NetDefend UTM Firewalls examine files of any size, using a stream-based virus scanning
technology which eliminates the need to cache incoming files. This zero-cache scanning
method not only increases inspection performance but also reduces network bottlenecks.
NetDefend UTM firewalls use virus signatures from Kaspersky Labs to provide systems with
reliable and accurate antivirus protection, as well as prompt signature updates. Consequently,
viruses and malware can be effectively blocked before they reach desktops or mobile devices.

performance capacity and maximize service availability. These firewalls use
granular policies and explicit blacklists and whitelists to control access to certain
types of websites for any combination of users, interfaces, and IP networks. The
firewall can actively handle Internet content by stripping potential malicious
objects, such as Java Applets, JavaScripts/VBScripts, ActiveX objects, and cookies.
WAN Link Load-Balancing and Fault-Tolerance
Multiple WAN ports support traffic load balancing and failover, thus
guaranteeing Internet availability and bandwidth.
