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:
| Selector | Operator | Value | Action |
|---|---|---|---|
| Host | matches regex | .* |
Isolate |
If instead you need to isolate specific pages, you can list the domains for which you would like to isolate traffic:
| Selector | Operator | Value | Action |
|---|---|---|---|
| Domain | In | example.com, example.net |
Isolate |
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:
| Selector | Operator | Value | Action |
|---|---|---|---|
| Host | In | example.com |
Do Not Isolate |
Policy settings
The following optional settings appear in the Gateway HTTP policy builder when you select the Isolate action. Enable these settings to prevent data loss when users interact with untrusted websites in the remote browser.
