• Static White and Black Lists
Define websites that will be explicitly allowed or blocked, independent of their classification. There are 32 default
classification groups in NetDefend UTM firewalls to allow network administrators to control Internet usage.

VBScripts, ActiveX objects and cookies, all of which are popular methods for hacker attacks.
• Cost-Effective Web Content Filtering
D-Link’s WCF service is priced per firewall instead of per user, so an enterprise-level organization does not need to

provide web surfing control for an entire organization.
