Of websites leak user data to external third parties.
Of top global websites do not honor opt-in consent as required by GDPR and CCPA.
Of websites contain at least one vulnerable client-side component exposing users to security risks.
The Client-Side Data Blind-Spot
Modern data governance assumes protection begins at the server, but the security perimeter has shifted to the browser. While traditional controls secure data once it reaches your network, organizations have zero visibility or control at the point of creation—the moment a user enters information into a website.
Jscrambler automatically identifies all third- and fourth-party scripts on your site, mapping their access to sensitive data (such as credit card or login fields) to expose overprivileged scripts and hidden data access patterns before data leakage occurs.
Jscrambler implements a least-privilege model in the browser, limiting script access to sensitive DOM elements. This prevents unauthorized data collection prior to consent, stops data leakage, and enforces strict minimization practices at the point of data creation.
Jscrambler monitors all script behavior to detect unauthorized data access and transfers in real time, generating detailed, audit-ready logs. This telemetry helps demonstrate compliance with strict regulations such as GDPR, CCPA, HIPAA, and PCI DSS v4.
Continuous Script Inventory
Maintain a real-time inventory of all scripts executing in the browser and their associated data access permissions.
Sensitive Data Access Mapping
Visualize which scripts can access sensitive form fields and user inputs, enabling rapid identification of overprivileged scripts and hidden data flows.
Behavior-Based Activity Monitoring
Detect unauthorized data collection, suspicious script behavior, or real-time data exfiltration attempts during live user sessions.
Granular Form Fencing
Enforce least-privilege access to sensitive application elements and user data to prevent unauthorized data collection.

“Other solutions allow you to monitor cross-site scripting or visit CSP policies, but that’s all they do. They won’t protect forms. They won’t ask, “Is this sensitive data? Yes or no?” For us, Jscrambler was the best platform because they do it all.”
Transform the browser from an ungoverned environment into a secure extension of your enterprise perimeter where data is protected at the point of creation.
