The most effective way to ensure that all web traffic is filtered is to enforce the use of a web proxy via

user policy. By configuring the ChromeOS devices to use a proxy server, all internet traffic will be

routed through the proxy, where filtering rules are applied.

Verified Answer from Official Source:

The correct answer is verified from the Google ChromeOS Network Management Guide, which

recommends using a web proxy to manage and filter web traffic efficiently.

"To enforce web filtering policies, configure a web proxy through user policies. This ensures that all

consistent and scalable content filtering across the organization.
