With web categories, you can organize and classify domains and keywords in a container. You can use categories within policies to control access to websites.
Within a category, you can create a list of domains and keywords specific to your organization or import a database. These include country-specific blocklists and open-source categorization lists. Sophos Firewall checks for updates every two hours.
For web pages categorized as highly objectionable criminal activity, Sophos Firewall acts as follows:
- Always blocks these web pages. It won't implement any policy or exclusion that allows these pages.
- Hides the domain name in logs and reports.
Classification: Categorization that lets you filter and manage categories.
Traffic shaping policy: Policy that determines usage limits and the bandwidth allocated for upload and download traffic.
