Mar 29, 2022Tim Obezuk
Summary
This post details how Cloudflare's Zero Trust and Remote Browser Isolation (RBI) services provide proactive protection against zero-day browser vulnerabilities, specifically referencing CVE-2022-1096. It explains the layered defense strategy: traffic steering via a roaming client, inspection and filtering by a secure web gateway, and execution of website code in a remote browser. It highlights RBI's ability to isolate endpoints, destroy and reconstruct browsers, encrypt egress traffic, and log egress traffic for incident response. The post contrasts the manual patching of local browsers with the automatic patching of remote browsers on Cloudflare's network.
