Page Shield: Protect User Data In-Browser

Cloudflare introduces Page Shield, a client-side security product designed to detect attacks in end-user browsers. The Magecart hacker group has stolen payment credentials from online stores by infecting third-party dependencies with malicious code. Page Shield helps customers monitor potential attack vectors and prevent confidential user information from falling into the hands of hackers. Existing browser technologies such as Content Security Policy (CSP) and Subresource Integrity (SRI) provide some protection against client-side threats but have drawbacks. The first available feature of Page Shield is Script Monitor, which records a site's JavaScript dependencies over time and alerts customers when new files appear. Cloudflare plans to add code change detection and intelligent analysis of JavaScript files in the future. Business and Enterprise customers can sign up for the closed beta of Page Shield starting today.
