How is GlobalView URL Filtering Implemented?
GlobalView URL Filtering is typically integrated into a service provider environment or a vendor device such as a Web Security Gateway. It consists of an engine that resides in existing Web security offerings and an “in the cloud” detection and categorization center (the GlobalView Network). These provide URL filtering and Web security functionality. After integration within the service provider environment or vendor device, URLs can be fed to the GlobalView URLF engine to determine the URL category. The engine first checks its local cache for URL categorizations – typically 99% of queries receive a local response. If necessary, the GlobalView URLF engine queries the cloud-based GlobalView Network for relevant updates. The vendor device or service provider server then blocks, allows or strips content according to defined policies for the returned categories.
