Problem
Websites are increasingly vulnerable to digital skimming attacks originating from third-party JavaScript, which can compromise sensitive data and lead to financial losses. Traditional security measures like Content Security Policy (CSP) and Subresource Integrity (SRI) often fail to adequately protect against these sophisticated client-side threats. Meeting PCI DSS 4.0 requirements 6.4.3 and 11.6.1 adds complexity for organizations seeking to secure credit card payment flows.
Solution
Source Defense offers real-time detection and protection against digital skimming and Magecart-style attacks stemming from third-party scripts. The patented technology analyzes the behavior of JavaScript code executing within a website user's browser, identifying and blocking malicious activity before it can exfiltrate sensitive data. By isolating and controlling the actions of third-party scripts, Source Defense prevents unauthorized access to payment information, personal data, and other confidential assets. The platform helps organizations comply with PCI DSS 4.0 requirements, specifically addressing client-side security gaps without burdening security teams.
Target Audience
The primary target audience includes e-commerce businesses, financial institutions, healthcare organizations, and any website that collects sensitive user data and must comply with PCI DSS or other data privacy regulations.
