UTM FIREWALLS
The NetDefend UTM firewalls incorporate an Intrusion Prevention System (IPS), gateway Anti-Virus (AV), and Web Content Filtering
(WCF) for superior Layer 7 content inspection protection. These firewalls use a hardware accelerator approach to increase IPS and
AV throughput, and a web surfing control database containing millions of URLs for WCF. IPS, Anti-Virus and URL database real-time
update services protect enterprise networks from application exploits, network worms, malicious code attacks, and provide everything
businesses need to manage employee Internet access behavior. Maintaining an effective defense against the various threats originating
from the Internet requires that all three databases used by the UTM firewalls are kept up-to-date. In order to provide a robust defense,
D-Link offers NetDefend Firewall UTM Services which include distinct NetDefend service updates for each aspect of network defenses:
IPS, Anti-Virus, and WCF. NetDefend Firewall UTM Services ensure that each of the UTM firewall’s service databases is always
accurate and current.
