Introduction

Cisco Umbrella Chromebook client

The Cisco Umbrella Chromebook client provides DNS layer protection for Chromebook users whether they are connected to your networks or remotely, no matter which Chromebook device they use.

You can use the Chromebook client to accomplish three main goals:

  • Protection from phishing: Protect against phishing threats automatically with Umbrella’s global network data and predictive intelligence to discover internet infrastructure used to host phishing sites—before employees or students ever receive the phishing email.
  • Content category filtering: Gain visibility and control of content on and off network. Organizations can help ensure compliance with the Children’s Internet Protection Act (CIPA) utilizing over 80 content categories, as well as their own allow and block lists of domains.
  • Per-user visibility and policy: Enforce policy-based protection whether users are on or off the network. If user becomes infected, pinpoint activity to a specific user to expedite remediation.

How the Umbrella Chromebook client works

Chromebook users are protected by the Cisco Umbrella Chromebook client in the following sequence:

  • A user enters a URL in the Chromebook browser.
  • The Chromebook client extension copies the domain name from the URL and sends it to the Chromebook client app.
  • The app creates an EDNS query, then sends the DNS request, including the EDNS information, to the Umbrella resolver.
  • Depending on the applicable policies applied in the Umbrella dashboard, the resolver responds by either blocking the IP address of disallowed domains or resolving the IP address in the case of acceptable domains.

The Umbrella Chromebook client is deployed using a Chrome extension and application available on the Chrome Web Store. For more information about how to deploy the Chromebook client, see Deploying the Chromebook Client. If you have more questions, see the Chromebook client FAQ.
