Isolation policies

With Browser Isolation, you can define policies to dynamically isolate websites based on identity, security threats, or content.

Isolate

When an HTTP policy applies the Isolate action, the user’s web browser is transparently served an HTML compatible remote browser client. Isolation policies can be applied to requests that include Accept: text/html*. This allows Browser Isolation policies to co-exist with API traffic.

The following example enables isolation for all web traffic:

If instead you need to isolate specific pages, you can list the domains for which you would like to isolate traffic:

SelectorOperatorValueAction
DomainInexample.com, example.netIsolate

Do Not Isolate

You can choose to disable isolation for certain destinations or categories. The following configuration disables isolation for traffic directed to example.com:
