Pass PCI 4.0.1 While Protecting Your Users
CSPs, JS agents, and crawlers may check the compliance box but they don't truly protect users. See how VikingCloud validated our PCI DSS solution.

FAQ
Frequently Asked Questions
Requirement 4.6.3 focuses on payment page script management, requiring you to authorize every script, ensure their integrity, and maintain a complete inventory with written justification for each script's necessity. Requirement 11.6.1 mandates continuous monitoring to detect unauthorized changes to HTTP headers and payment page content, with alerts sent to personnel and evaluations performed at least weekly.
PCI DSS 4.0.1 is the latest version of the Payment Card Industry Data Security Standard that protects cardholder data through strict security monitoring requirements. If your business processes, stores, or transmits credit card information, you must comply with these regulations to avoid hefty fines, higher insurance rates, and potential business disruption. The standard applies to all merchants, processors, acquirers, and service providers handling payment card data. Non-compliance can result in fines ranging from thousands to millions of dollars, depending on your transaction volume and the severity of any breaches.
PCI DSS requirement 4.6.3 requires active and constant monitoring, while 11.6.1 requires monitoring to occur at least once every seven days, or at the frequency defined in your organization's targeted risk analysis. However, given that cyberattacks happen in real-time and malicious scripts can be injected at any moment, continuous (real-time) monitoring provides the best protection.
Non-compliance penalties vary based on your payment processor and transaction volume, but fines typically range from $5,000 to $500,000 per incident. Beyond fines, you may face increased transaction fees, higher insurance premiums, loss of payment processing privileges, and significant costs from data breach remediation and lawsuits. The average cost of a payment card data breach exceeds $4 million when factoring in forensic investigations, legal fees, customer notification, and business disruption.
During a PCI DSS audit, qualified security assessors will review your compliance documentation, test your security controls, and verify that you're meeting all applicable requirements. For requirements 6.4.3 and 11.6.1, auditors will examine your script inventory, review authorization documentation, test your monitoring systems, and verify that you're detecting unauthorized changes. Having automated monitoring with csside means your compliance documentation is always current and audit-ready, with detailed logs, weekly reports, and clear evidence of continuous monitoring that auditors can easily review and validate.
Proxy-based solutions provide the most comprehensive protection because they intercept and analyze every script request in real-time, rather than just scanning periodically or relying on browser-based detection that attackers can bypass. cside's proxy approach ensures complete visibility into script behavior, immediate threat blocking capabilities, and accurate compliance reporting that captures all script variations. This method has been independently audited and approved by Viking Cloud, giving you confidence that your compliance strategy meets the highest industry standards while providing superior security protection.
