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 realtime 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 enterpriselevel 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. 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. Public web server 3. If granted by the corporate surfing policy, the user will gain access to the requested website. Surfing policy for engineering department Adult: Block / Shopping: Block / News: Allow
