Secure your browser runtime against OWASP A03: Software Supply Chain Failures with continuous client-side governance and security at runtime.
As modern web applications dynamically assemble third-party scripts and payment flows inside the browser, they bypass traditional deployment pipelines. The OWASP A03 elevation underscores the danger: these unmonitored components update independently at runtime and inherit broad privileges by default, introducing critical client-side supply chain risks that build-time security (SBOMs) and server-side tools completely miss.
92%
of all web pages load dynamic third-party resources directly in the user’s browser.
50%
of the JavaScript executing on modern e-commerce websites originates from unvetted third-party sources.
70K+
websites have been silently compromised by Magecart-style web skimming and formjacking attacks.
Jscrambler provides a control plane that converts OWASP A03 guidelines into automated runtime enforcement. The platform protects application logic from tampering, detects third-party supply chain risks, and enforces least privilege to isolate runtime execution and block data exfiltration.
Jscrambler automatically discovers and inventories all client-side scripts and assigns risk scores during live sessions, giving security teams comprehensive client-side supply chain visibility.
Jscrambler applies precise, field-level data fencing rules that restrict third-party scripts to only their intended functionality.
Jscrambler continuously monitors third-party runtime behaviors, immediately detecting and blocking anomalous behaviors, such as function hijacking or unauthorized data transfers.
Jscrambler provides continuous auditing and reporting of client-side activity to eliminate the visibility and control gaps targeted by OWASP Top 10 A03.
“From what I see, Jscrambler is the most complete solution there is. Not only does it offer monitoring, it provides us with comprehensive protection for forms and scripts.”
