PCI DSS 4.0.1 expects protection across infrastructure and inside the browser. DataStealth is a data security platform that discovers, classifies, and protects sensitive data with tokenization, encryption, and masking, and it positions PCI support that can shrink audit scope without code changes. It also markets a no-code tamper protection approach that validates payment page scripts for 6.4.3 and 11.6.1. PaymentGuard AI specializes in real-time client-side monitoring on checkout pages and automates evidence for those same requirements. Used together, you connect data-centric protection with continuous browser-side assurance.
DataStealth: Data discovery, tokenization, masking, and PCI scope reduction
DataStealth is a data security platform that discovers sensitive data across cloud, on-premises, SaaS, and legacy systems, then applies tokenization, masking, or encryption based on policy. The company positions PCI outcomes such as reduced audit scope, and describes no-code integration paths that can route and protect data without changing applications. DataStealth materials also describe tamper protection for PCI DSS 6.4.3 and 11.6.1 by validating payment page scripts in real time, along with public references to Level 1 Service Provider status and participation with the PCI Security Standards Council.
Key strengths:
- Tokenization, masking, and encryption to protect data without disrupting apps
- PCI positioning that includes audit scope reduction and no-code deployment patterns
- Messaging about script tamper protection for 6.4.3 and 11.6.1
Feroot PaymentGuard AI: Real-time client-side protection and evidence
PaymentGuard AI focuses on what loads in the customer’s browser. It inventories and authorizes every script and third-party tag on payment pages, watches runtime behavior for unexpected changes or new network calls, and produces auditor-ready logs mapped to PCI DSS 6.4.3 and 11.6.1. This gives your team continuous proof that scripts executing in checkout flows behave as intended and that evidence is ready for QSA review.
Key strengths:
- Live inventory and authorization of payment page scripts with continuous monitoring
- Behavior analysis that detects tampering, injection, and data exfiltration in the browser
- Automated, QSA-ready reporting aligned to 6.4.3 and 11.6.1

| PCI DSS alignment | Automates evidence for 6.4.3 and 11.6.1 through client-side monitoring and change detection | PCI materials emphasize scope reduction and protection; site and blogs describe script tamper protection intended for 6.4.3 and 11.6.1, along with broader PCI outcomes |
| Control domains | Browser scripts, payment page integrity, client-side data protection | Data-centric controls across apps, databases, files, and traffic, plus marketed payment page tamper protection |
| Threat monitoring | Detects script tampering, unauthorized DOM changes, and data leaks in the browser | Substitutes or transforms sensitive data via tokenization and masking, enforces encryption, and validates scripts per marketing content |
| Evidence automation | QSA-ready logs and client-side compliance reports mapped to 6.4.3 and 11.6.1 | PCI artifacts focused on scope reduction and platform analytics; messaging references no-code DNS-style enablement and reporting |
How PaymentGuard AI and DataStealth work together
These platforms cover different layers. DataStealth protects the data itself, replacing or encrypting sensitive fields so that even if systems are accessed, cleartext is not exposed, and PCI scope can be reduced. PaymentGuard AI protects the browser environment after the page loads by watching scripts for unauthorized behavior, then producing evidence mapped to 6.4.3 and 11.6.1. In practice, teams can route PaymentGuard AI alerts and reports into their compliance workflow while using DataStealth’s tokenization or masking to limit exposure and simplify audits.
How to decide which solution works best for your organization
Choose DataStealth when your priority is to discover where sensitive data lives, replace or mask it without changing applications, and reduce the PCI assessment footprint.
Choose PaymentGuard AI when you need continuous, script-level visibility inside customer browsers and auditor-ready proof that payment page monitoring and integrity checks are operating as required.
Many teams adopt both to align data-centric controls with live client-side assurance.
FAQ
How does PaymentGuard AI differ from DataStealth’s tamper protection?
PaymentGuard AI monitors every script and tag running in the browser in real time, detecting changes, behavioral anomalies, and data exfiltration attempts as they occur. DataStealth’s tamper protection validates scripts based on platform-defined checks but is not designed as a full client-side observability and compliance automation layer.
Can PaymentGuard AI and DataStealth be used together?
Yes. Many teams combine the two. DataStealth protects sensitive data at rest and in motion through tokenization, masking, and encryption, while PaymentGuard AI ensures the scripts running on payment pages remain safe and compliant. Together, they offer protection at both the data layer and the client side.
How does PaymentGuard AI help during PCI DSS audits?
PaymentGuard AI generates clear, structured evidence that maps directly to PCI DSS 6.4.3 and 11.6.1. Auditors can review script inventories, change histories, alert timelines, and monitoring logs to confirm continuous client-side oversight. This reduces manual preparation, shortens review cycles, and gives QSAs a straightforward way to validate that browser-side controls are operating effectively.
Summary
DataStealth and PaymentGuard AI address different needs in PCI DSS 4.0.1 DataStealth applies tokenization, masking, and encryption to protect data everywhere and can help reduce PCI scope, while marketing a no-code approach to payment page tamper protection. PaymentGuard AI delivers dedicated client-side monitoring and automated evidence for 6.4.3 and 11.6.1 where customers enter card data. Used together, they strengthen protection and provide verifiable coverage from the data layer to the browser.
