Google is beefing up the security for Chrome on Android.

The Mountain View company has announced its Site Isolation feature – that originally launched for desktops last year – is coming to Android devices.

In a nutshell, Site Isolation ensures your data is harder for malicious third-parties to access, even if you have fallen victim to a bug throughout your travels online.

More specifically, the feature forces all web pages to operate in different isolated environments. This means if a bug does gain access to particular data you’ve entered on a single page, you won’t have to worry about it getting hold of information from other site’s you’ve visited too.

Google has declared Site Isolation on Android should help to combat against two particular types of threats: side channel attacks like the infamous Spectre that was discovered last year, and security bugs within a particular browser.

Unlike on desktops where Site Isolation is employed for all sites, Google has said on Android the functionality will be limited to pages that hold “sensitive data”.

The American tech giant explained: “Site Isolation is turned on only for high-value sites where users log in with a password.

“This protects sites with sensitive data that users likely care about, such as banks or shopping sites, while allowing process sharing among less critical sites.”

Google has insisted the new security defence for Chrome shouldn’t impact its performance for users. In fact, the tech giant has said the feature will only be available on Android devices with 2GB of RAM or more (which is most phones out there).

Site Isolation is being turned on for all Android devices running Chrome version 77. It’s likely you’re already running this iteration of Chrome, as it released over a month ago.

Of course, the security feature will also work with Chrome version 78 that is expected to release on October 22.

Chrome 78 will make a number of notable changes to the popular browser, chief of which is the embedding of Google’s Password Checkup extension into Chrome, rather than offering it as an extension.

As a quick reminder, Password Checkup will detect and alert users if a password they are using has been compromised. will be on hand to let you know the moment Chrome 78 releases.
