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 in terms of Internet resource allocation for your organization.
NetDefend Web Content Filtering helps MIS 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 sometimes scarce
Internet resources.
Organizations gain 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 child 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.
Features and Benefits
• Global Index Servers
Global index servers maintain databases of millions of URLs and collect real-time website information about the latest
sites 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.
