Every time a user clicks on a website link, their web browser processes and loads a lot of external data into their local system. Organizations like Cloudflare help ensure that users can reduce any risks associated with harmful content from the internet.
Companies like Cloudflare work by shifting the responsibility for executing unknown code from the user's device to an isolated remote browser. This makes it harder for even the most recent threats, such as zero-day attacks, to gain access to targeted assets and data.
Now Cloudflare has introduced Cloudflare Browser Isolation for teams of any size. This feature is an addition to their suite of zero-trust security and secure web browsing services. From startups to large corporations, this add-on allows organizations to browse securely without installing complex network topologies or changing their web browser of choice.
However, despite the clear benefits of Remote Browser Isolation (RBI), many organizations have been hesitant to implement such solutions for many years due to concerns about the impact on web browser performance. After all, the benefits of a security solution hardly outweigh the risk of downtime, or even just lagging behind in network availability, potentially resulting in poor performance.
Therefore, in light of the long-standing negative impact on browser activity due to the implemented RBI, many IT organizations apply this increased security posture only to highly targeted activities and users. Unfortunately, by assuming that certain types of websites are inherently secure, many companies risk a vast array of potentially harmful websites left easily accessible by unsuspecting users.
To explain the ever-evolving Internet landscape, Cloudflare built its isolation browser on top of Chromium, the same engine that fuels other well-known web browsers such as Google Chrome and Microsoft Edge. Along with its new network rendering technique, the company helps ensure that web pages are displayed consistently and safely. Similar to the sandbox view, Network Vendor Rendering offers a snapshot of the contents of an unknown web page.
In terms of maintaining the speed of the web browser while the RBI is active, Cloudflare has made their solution run as fast as possible. Along with the ability of the network rendering provider to display the content of a web page without significantly using bandwidth or reducing the quality of the image, the team also created remote browsers near all users connected to the Internet. Thus, all participants can use the solution regardless of the geographical location and proximity to the Cloudflare office.
With nearly 30 million users in the U.S. without access to broadband Internet, Browser Isolation helps by offering those users with low-bandwidth connections an equally secure browsing experience.
