Enable Web Category Blocking blocks sites based on their content category, which Trellix defines.
Web Control provides more filtering options. Enable Web Category Blocking classifies sites based on their content and block them. Use this option to block access to sites that are categorized as malicious content, such as pornography, spyware, adware, or phishing.
Enable Web Category Blocking overrides the Rating Actions for Sites configuration. For example, the Rating Actions for Sites is set to Allow for yellow-rated sites with Enable Web Category Blocking enabled for all categories. If you visit a yellow-rated site that belongs to the blocked category, the software blocks the site although the Rating Actions for Sites configuration allows access to yellow-rated sites.
