Enable Strict Site Isolation in Google Chrome

Google Chrome web browser is now offering very tough security measures for individual users. One of the options available in the newest version (version 67) of Google Chrome is called Strict Site Isolation. Using this feature, you can force all websites to use their isolated separate renderer process. This way one website cannot in any possible way access the data of another site in real time. This also improves protection against processor vulnerabilities like Spectre.

But as of now it is only an experimental feature. Here is how you can enable it in your installed copy of Google Chrome web browser:

  1. Launch Chrome web browser.
  2. Type chrome://flags in the address bar and press Enter.
  3. In the search box type strict site isolation to find the setting we want.
  4. Change the status for this setting from Disabled to Enabled.
  5. When asked relaunch Chrome web browser and you are all set.Chrome Strict Site Isolation

Now when you open websites, they will use one process for each of the sites. This could spawn a large number of processes if you open multiple websites in your Chrome web browser, but it will make your data very secure. For example, when you enter login credentials on one website, it cannot be accessed by any other process.

But this setting should be enabled only when you open a small number of websites, or you will see Chrome launching a large number of processes and this can impact the overall performance of your Windows computer. However, if your computer is sufficiently powerful then you do not have to worry about it and can go ahead and enable this setting for improving the security a level more for your Chrome web browser.
