About Remote Browser Isolation

You can use browser isolation, which is also known as Remote Browser Isolation (RBI), to ensure web access is secure for users of your organization.

When a user sends a request to access a website with browser isolation enabled, the original content of that website is not sent in response to the user's browser, but to a browser on a remote server.

From there, a real-time, interactive image of this content is transferred to the user's browser. This ensures the user's browser and system are protected against threats arising from the original content, for example, against infections by viruses and other malware inhering in this content.

Using browser isolation, you can allow users access to websites that would otherwise be blocked under your web policy because accessing them was considered an unacceptable risk.

The user is notified when browser isolation is applied. For this purpose, the representation of the original web content is marked by a green border around any page that is displayed in the user's browser.

The browser isolation process is controlled by the rules of your web policy. These rules filter web traffic relying for their execution on the web proxy functions that are implemented under Secure Web Gateway.

There are two rule sets offering different modes of browser isolation. You can configure them as part of configuring your web policy under Secure Web Gateway.

• Risky Web — Browser isolation is used when access to a website is considered a risk.
  
  Whether access to a website is considered a risk is determined by the web security functions that are implemented under Secure Web Gateway. But you can configure exceptions and other settings.
  
  For more information, about how to configure this rule set, see Risky Web — Use Browser Isolation for Websites Considered a Risk.

• Full Isolation — Browser isolation is used for access to a website according to criteria that you select.
  
  For more information about how to configure this rule set, see Full Isolation — Use Browser Isolation for Websites Based on Your Own Selection.
