Discover Why Traditional Defenses Fall Short Against eSkimming Attacks
Download the Free eBook: Behavior-Based vs CSP and SRI: Which is more effective?
Web-based attacks are evolving, and most organizations aren’t ready. While legacy defenses like Content Security Policy (CSP) and Subresource Integrity (SRI) provide limited, static protection, today’s threats demand a more dynamic response.
This free eBook offers a deep dive into the critical gap in web security that 97% of consumer-facing websites fail to address: protection of third-party scripts in the browser. You’ll learn why behavior-based security is rapidly becoming the new standard for defending against:
- eSkimming and Magecart attacks
- Credential harvesting and formjacking
- Data leakage from third- and fourth-party JavaScript
AI-generated keyloggers and real-time script manipulation
What You Will Learn
- Why CSP and SRI fall short in dynamic web environments
- How behavior-based security blocks threats at the point of data entry
- How to meet PCI DSS 4.0 requirements 6.4.3 and 11.6.1—without heavy lift
- Real-world case studies showing 100% prevention of unauthorized data access
Actionable steps to assess and close your client-side security gap
Why It Matters
PCI DSS 4.0 requirements for payment page script control and monitoring are no longer optional. Traditional tools can’t keep up with evolving attacker tactics—and failing to meet compliance could result in penalties, reputational damage, and lost customer trust.
This guide cuts through the complexity, compares leading approaches, and lays out a fast path to compliance and protection.
