Remove Hidden Client-Side Supply Chain Risks in the Browser
Modern web apps use third-party scripts and dynamic services in the browser, creating an unmonitored attack surface. Compromised components can inject malicious code, skim data, or exfiltrate info, while traditional controls and SBOMs often fail to detect them.
Jscrambler provides real-time monitoring of browser scripts and data flows, detecting unauthorized or modified code, addressing a critical visibility gap that SBOMs and build-time inventories often miss when code is injected at runtime.
Jscrambler protects against client-side threats like digital skimming, code tampering, and malicious script injection by combining runtime monitoring with obfuscation and anti-tampering, detecting compromised scripts, blocking unauthorized data access, and securing application code after deployment.
Jscrambler continuously audits client-side activity, addressing the OWASP Top 10 gaps in visibility, integrity, and control over browser-executed code by reporting on scripts, behaviors, and access to sensitive data to provide evidence of policy enforcement.
Continuous Script Inventory
Real-time visibility of all scripts running on the website and how they access and transfer data. Provides an accurate picture of the overall exposure to third-party risk.
Advanced Skimming Detection & Analysis
Skimming Detection & Analysis leverages advanced static code analysis techniques to thoroughly examine and identify potential threats associated with skimming attacks. By analyzing the behavior of web scripts and the context in which they execute, the system detects various indicators commonly associated with skimming activity, such as obfuscation, stealth techniques, data encryption, injection of forms, iframes, and other elements of access 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.
Skimming Prevention & Behavior Blocking
Jscrambler offers a suite of powerful features that offer granular control and block malicious script behaviors while maintaining full functionality. Data fencing features are critical to controlling exactly which scripts can read and access data, and keeping malicious actors from stealing sensitive information that users enter into forms.
With Iframe Control, Jscrambler allows you to easily manage which vendors or scripts are permitted to create or manage iframes on your website.
Polymorphic Obfuscation
Advanced obfuscation transformations with built-in resilience against all reverse engineering tools and techniques. Its polymorphism ensures that each new build has a completely different output.
Runtime Anti-Tampering Protection
Protect your web application against changes or modifications to your code. The feature allows for the code to be repaired when that happens or for countermeasures to be deployed. Countermeasures can be specified (optionally) to execute when someone tries to tamper with the code.
Real-time Alerting
Immediately notice high-risk behaviors and gain real-time reaction capabilities, full application monitoring, and notifications.
Audit-Ready Reporting
Jscrambler provides a detailed assessment report covering all vendors, scripts, and authorizations, simplifying the audit process. This report will support you during internal and external audits.
