Jscrambler, the pioneering platform for client-side protection, today announced new independent research titled “Jscrambler: A Comprehensive Approach to Payment Page Security & PCI DSS v4.0 Requirements 6.4.3 & 11.6.1” Conducted by industry-leading cybersecurity services company and PCI Qualified Security Assessor (QSA), Coalfire, the assessment details the Jscrambler platform and how it helps businesses adhere to regulatory requirements, industry best practices, and broader cybersecurity frameworks and compliance standards, such as PCI DSS v4

The widespread adoption of first- and third-party JavaScript has made client-side environments significantly more vulnerable to attack and prompted groups such as the PCI Security Standards Council (PCI SSC) to establish data security protocols for secure global payments. This includes PCI DSS v4, an updated set of guidelines and requirements focusing on payment pages to ensure that cardholder data is handled, stored, and transmitted securely during payment card transactions.

PCI DSS v4 features new rules for how JavaScript should be handled on payment pages to prevent skimming attacks.

In this independent research assessment, Coalfire examined the Jscrambler platform for its alignment with specific PCI DSS requirements, including 6.4.3 and 11.6.1. According to the report, “Coalfire found that it can be effective in its ability to assist organizations in meeting these requirements set forth by the PCI SSC. The Jscrambler platform is capable of streamlining the effort required to establish the effective application of controls and to lower the overall effort required to demonstrate and maintain compliance. Its capabilities can assist in the reduction of operational stress on the required risk management teams and associated information technology staff to support the cybersecurity program, workloads, and business operations.”

The research also states that “the combination of Jscrambler's comprehensive first and third-party JavaScript protection, JavaScript obfuscation and fine-grained tag behavior controls, hardened agent, and managed expertise working on client-side security are all examples of capabilities in support of its effectiveness.”

“Visa's Spring 2023 Biannual Threats Report reported that digital skimming attacks targeting e-commerce sites increased by 174% in the last half of 2022 alone. The analysis from Coalfire is a testament to the capabilities of our unified client-side protection and compliance platform, which provides payment page script discovery, authorization, detection, and alerting. It’s through these insights that merchants can easily comply with the new requirements introduced in PCI DSS v4.0 while mitigating security threats targeting payments pages such as digital skimming, Formjacking, Magecart Attacks, and more,” said Rui Ribeiro, CEO & Co-Founder of Jscrambler.
