Achieve Compliance and Minimize the Risks of Sensitive Data Leakage
Many interactions, such as payments, identity checks, consent, and AI inputs, occur in the browser before security controls apply, creating a critical compliance gap that prevents organizations from enforcing policies and controlling data transmission in real time.
Jscrambler enforces consent, data minimization, and residency policies in the browser, restricting script access to sensitive fields and securing data transmission during live sessions. Least-privilege execution protects payment, health, and personal data while supporting PCI DSS v4, GDPR, HIPAA, and EU AI Act compliance.

Flexible Architecture (Agentless and Agent-Based)
Jscrambler offers deployment flexibility where you can go agentless or agent-based across each of your website pages. The integration is super fast, allowing you to bring as many pages into compliance as needed. All the data goes back to the same dashboard. There’s no lock-in, and you can switch deployment methods back and forth as your risk appetite changes.
Script Inventory, Integrity Assurance, and Justification
Maintains a real-time inventory of all scripts running on payment pages, along with justifications for their necessity and compliance status, helping organizations to keep track of and justify the use of each script as required by PCI DSS v4. Jscrambler implements methods to confirm each script is authorized, aligning with the requirement to verify script legitimacy.
Script and Header Change and Tamper Detection Alerts
Jscrambler sends alerts on unauthorized modifications to HTTP headers, ensuring data transmission security. Jscrambler monitors the content of payment pages as received by the consumer's browser, alerting to any unauthorized modifications, thereby preserving the integrity of the payment process.
Data Fencing and Granular Control
Protect your forms and sensitive data with Jscrambler's fine-grained security controls. By defining precise rules for script access and actions, you can immediately block unauthorized script behavior, preventing the leakage and exfiltration of sensitive data entered into website forms.
Behavioral Threat Detection
By analyzing the behavior of web scripts and the context in which they execute, the system detects indicators commonly associated with skimming activity, such as obfuscation, stealth techniques, data encryption, form and iframe injection, and other access mechanisms to sensitive data. By evaluating these and other factors within the script and page context, the end result provides a comprehensive assessment of whether skimming activity is present on the website.
Automated Compliance Reports
Jscrambler provides a detailed assessment report detailing all vendors, scripts, and authorizations, simplifying the audit process. This report will support you during internal and external audits.
