The Web Blocking List is downloaded by smart protection sources. Security Agents that are subject to web reputation policies do not download the Web Blocking List.

Agents subject to web reputation policies verify a website’s reputation against the Web Blocking List by sending web reputation queries to a smart protection source. The agent correlates the reputation data received from the smart protection source with the web reputation policy enforced on the endpoint. Depending on the policy, the agent will either allow or block access to the site.
