Increase security in Chrome with site isolation

When you turn on site isolation, Chrome offers more security protections for your browser.

Chrome will load each website in its own process. So, even if a site bypasses the same-origin policy, the extra security will help stop the site from stealing your data from another website. Learn more about site isolation.

To set up isolation:

  1. On your computer, open Chrome.

  2. In the address bar at the top, enter chrome://flags/#enable-site-per-process and press Enter.

  3. Next to "Strict site isolation," click Enable.

  • If you don't see "Strict site isolation," update Chrome.

  1. Click Relaunch now.

If you’re an administrator, learn how to manage site isolation for your organization.
