NetDefend Firewall UTM Services
NetDefend Web Content Filtering (WCF) Subscription
Web surfing control is becoming a critical concern for businesses of all sizes. D-Link’s Web Content Filtering (WCF) service enforces access protection and
management policy for Internet usage. NetDefend Web Content Filtering helps IT staff monitor, manage, and control employee usage of and access to the Internet. It
puts Management back in control, enabling a more business-orientated and cost effective use of Internet resources.
Organizations experience significant cost savings through:
1)
A reduction in wasted staff time
by reducing inappropriate web surfing.
2)
Reduced Internet access costs
and bandwidth savings by limiting and controlling non-business related uses, thus improving network response.
3)
Reducing legal exposure
to workplace conflicts and liabilities (e.g. sexual harassment cases or pornography and the adverse publicity that such incidents
can generate).
4)
Reduced costs in recovering from attacks
as much less inappropriate content will even be allowed to enter the network.
Global Index Servers
Global index servers maintain databases of millions of URLs and collect real-
time website information in order to keep the data as current as possible.
Multiple servers worldwide enhance performance and maximize service
availability wherever a NetDefend firewall is installed.
Performance Optimized
D-Link implements multiple index servers to enhance performance capacity
and maximize service availability. Categories of recently visited websites are
cached locally in each UTM firewall to maximize performance for subsequent
requests.
Tight Integration with other
D-Link Security Gateway Subsystems
D-Link allows you to define highly-granular policies for allowing or disallowing
where and when access to certain types of websites is permitted, and different
policies can be applied to any combination of users, interfaces, and IP
networks.
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.
Active Content Handling
The WCF capabilities of D-Link UTM firewalls can strip potential malicious
objects, such as Java applets, JavaScripts / 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 contemplate a large TCO for licensing in
order to manage the surfing privileges of all employees. One subscription can
provide web surfing control for an entire organization.
Multiple replicated databases are deployed worldwide to
maximize performance and availability.
1. User requests a web page.
Public web server
2. A global database is queried for the
category of the web page.
2b. If the database does not contain the
requested information, the web page
is downloaded by the database and
analyzed using several techniques.
3. If granted by the corporate surfing policy, the user
will gain access to the requested website.
