Page Shield: Protect User Data In-Browser
Mar 25, 2021Justin Zhou
Summary
Introduced Page Shield, a client-side security product to detect attacks in end-user browsers, specifically targeting supply chain attacks via third-party JavaScript. The first feature, Script Monitor, alerts customers to new JavaScript dependencies by leveraging a Content-Security-Policy-Report-Only header. Future plans include code change detection and intelligent analysis of malicious JavaScript, with a negative security model for blocking scripts.
