Cloud-Based Web Filtering: A Comprehensive Guide
What is Cloud-Based Web Filtering?
Cloud-based web filtering is a technology that allows organizations to control internet access and content visibility for users on their network by utilizing a cloud-based service. It provides centralized management, real-time updates, and a comprehensive set of filtering features that can be accessed remotely.
How Does Cloud-Based Web Filtering Work?
- Traffic Redirection: User traffic is directed to the cloud-based filtering service.
- Content Inspection: The service analyzes web content, URLs, and other data to determine if it aligns with the organization’s policies.
- Filtering Decisions: Based on the analysis, the service decides whether to block or allow access to the website or content.
- Traffic Routing: The filtered traffic is then routed back to the user, either granting or blocking access.
