"One of the most important reasons we went with Reflectiz is that it doesn't need to know transaction details. That eliminated security and privacy concerns and third-party risk immediately."
Zero Audit Findings. No-Code Installation.
No Access to Payment Data.
Remote, agentless PCI DSS 4.0.1 compliance for requirements 6.4.3 and
11.6.1: deployed in 24 hours.
What the Reflectiz PCI Module Does
More than half of third- and fourth-party applications running on monitored sites access sensitive data with no documented business justification. PCI DSS v4.0.1 requirements 6.4.3 and 11.6.1 exist to close exactly that gap, and the Reflectiz PCI Module automates the work of meeting them.
The Reflectiz PCI Module is a purpose-built compliance solution for PCI DSS v4.0.1 requirements 6.4.3 and 11.6.1. It runs entirely remotely: submit a payment page URL, and it begins monitoring within hours (one day onboarding), and automates the work that consumes the most time before and during a QSA audit: script inventory, behavioral approval, business justification documentation, and compliance evidence generation.
Reflectiz is a Principal Participating Organization in the PCI Security Standards Council and works directly with the Council to shape evolving guidance. The module is available as a standalone solution or as part of the Reflectiz Security Hub.

How the PCI Module Works
Key Capabilities
Recognized at the top tier by the PCI Security Standards Council
As a PPO, Reflectiz contributes directly to PCI SSC Technology Guidance Groups, helps to shape ongoing updates of the Data Security Standard, and gains early visibility into emerging standards, keeping the Reflectiz PCI Dashboard aligned with every evolution of PCI DSS.
In April 2026, Reflectiz joined the PCI SSC’s Coffee with the Council podcast alongside BT Group and Salesforce to discuss the value of PPO participation, the findings of the State of Web Exposure 2026 Report, and how third- and fourth-party script risk is shaping the future direction of payment security standards. Brett Johnson, Reflectiz’s Americas lead, highlighted a striking pattern in the data: more than half of third- and fourth-party applications running on monitored sites access sensitive information with no documented business justification. This is the exact gap requirements 6.4.3 and 11.6.1 were designed to close.

A note on agent-based architectures
Solutions that require agent or tag deployment introduce a third-party component into the payment environment, requiring teams to evaluate the agent itself as a compliance and privacy risk. This was the specific concern Apexx Global’s Head of Information Security cited as the reason for selecting Reflectiz over every agent-based alternative they evaluated.
The SAQ A Consideration
Updated SAQ A guidance gives eligible merchants a path to potentially simplify their compliance obligations, but only if they can affirmatively demonstrate that their entire website is protected from script-based attacks, including Magecart and web skimming. In effect, the new SAQ A now demands the very monitoring that it was meant to spare you.
Reflectiz provides the full-site script visibility, including the iFrame coverage that most tools cannot deliver, required to establish SAQ A eligibility and sustain it continuously between audit periods.
Security Beyond the Payment Page
PCI compliance PCI Compliance secures the payment page. It does not secure the rest of your web environment, and most client-side attacks don’t start at checkout. Reflectiz Security Hub provides continuous visibility and control across your full web surface, detecting malicious script activity, web supply chain risks, misconfigurations, and unauthorized data access. Reflectiz Privacy Hub gives compliance and legal teams visibility into how user data is accessed, collected, and shared across web properties, supporting alignment with GDPR, CCPA, HIPAA, and other privacy obligations alongside your PCI posture.

FAQ
What is the Reflectiz PCI Module?
The Reflectiz PCI Module is a dedicated PCI DSS v4.0.1 compliance solution that automates script inventory management, unauthorized change detection, Smart Approval workflows, and QSA-ready evidence generation for requirements 6.4.3 and 11.6.1, with no agent installation,, no code changes, and no access to payment or user data.
Does the Reflectiz PCI Module require code changes or agent installation?
No. The Reflectiz PCI Module operates entirely via remote execution. No agent is installed, no JavaScript tag is deployed, and no access to the production environment is required. Organizations provide payment page URLs, and Reflectiz monitors them remotely.
How does Reflectiz fulfill PCI DSS requirement 6.4.3?
Reflectiz fulfills requirement 6.4.3 by maintaining a continuously updated inventory of every script on payment pages (including third-party, fourth-party, and iFrame scripts) and providing an individual approval and documented justification workflow for each, aligned with the examine, observe, and interview procedures in PCI DSS 4.0.1 guidance.
How does Reflectiz fulfill PCI DSS requirement 11.6.1?
Reflectiz fulfills requirement 11.6.1 by continuously monitoring HTTP response headers on payment pages and generating real-time alerts whenever an unauthorized change is detected. Each alert is accompanied by a timestamped evidence log capturing the precise nature of the change (including modified, added, or removed headers) in a format aligned with the PCI DSS 4.0.1 examination procedures. These logs are available on demand for QSA review and can be exported directly from the Reflectiz PCI Dashboard.
Can Reflectiz generate the evidence my QSA needs?
Yes. The Reflectiz PCI Dashboard generates one-click compliance evidence exports covering script inventories, individual business justifications, approval status, domain change logs, user activity logs, and evidence logs, in formats aligned with PCI DSS 4.0.1 QSA examination procedures.
Has the Reflectiz approach been reviewed and approved by QSAs?
Yes. Multiple Reflectiz customers have confirmed that their QSAs reviewed and approved the Reflectiz approach without caveats. lastminute.com’s Director of Platform Security confirmed auditor approval before selecting the tool. Reflectiz is also a Principal Participating Organization in the PCI Security Standards Council.
What changed in PCI DSS v4.0.1, and why do requirements 6.4.3 and 11.6.1 matter now?
PCI DSS v4.0.1 made requirements 6.4.3 (script inventory and authorization) and 11.6.1 (HTTP header change detection) mandatory best practices as of March 2025. Organizations that previously relied on self-attestation now need documented, continuous, and auditable controls – not point-in-time assessments. Non-compliance can result in failed QSA audits, elevated assessment scope, and increased liability exposure in the event of a breach.
How is Reflectiz different from agent-based or tag-based script monitoring tools?
Agent-based and tag-based tools require JavaScript to be deployed on the payment page – introducing additional attack surface, requiring developer involvement, and often failing to detect fourth-party scripts loaded by third parties. Reflectiz operates entirely remotely with no code on the page, monitoring the rendered output including iFrames, fourth-party scripts, and dynamically injected content that tag-based tools cannot reach.
What are fourth-party scripts, and why does Reflectiz cover them?
Fourth-party scripts are JavaScript files loaded by your third-party vendors – a chat widget that itself loads an analytics tracker, for example. PCI DSS requirement 6.4.3 requires authorization and justification for all scripts on a payment page, including fourth-party ones. Most tools inventory only scripts you directly load. Reflectiz inventories the full chain, including scripts that are two or three vendor relationships removed from you.
How long does deployment take?
Most organizations are fully operational within 24 hours of providing payment page URLs. Apexx Global’s deployment was live in under 24 hours. Village Roadshow’s four-site deployment was complete in two days with no code changes and no developer involvement.
Does Reflectiz access payment data or user PII?
No. Reflectiz takes a remote, agentless approach. It operates externally with no code insertion and zero access to payment data, session information, or user PII. This architecture was specifically cited by Apexx Global’s Head of Security as the reason Reflectiz was selected over agent-based alternatives.
Can Reflectiz handle multiple brands or payment pages?
Yes. Bulk Approval allows identical script behaviors to be approved across all sites in a single action. The Aggregated Report consolidates compliance data from all properties into one report. Reflectiz is designed for enterprise organizations that operate multiple brands with numerous checkout pages across various territories.
What happens when a previously approved script changes?
Reflectiz detects behavioral deviations in real time and alerts the security team. The script’s approval status updates to reflect the change, and the team can review, generate a new AI-assisted justification, and re-approve – maintaining a continuous compliance posture rather than point-in-time snapshots.
How does Reflectiz support SAQ A eligibility?
Updated SAQ A guidance requires owners to demonstrate that the entire website is protected from script-based attacks. Reflectiz provides full-site script visibility – including iFrame coverage that most tools cannot deliver, plus continuous monitoring,, enabling organizations to establish and sustain SAQ A eligibility. In practical terms, SAQ A-eligible merchants benefit from a significantly reduced compliance scope: fewer controls to implement, a shorter self-assessment questionnaire, and a lighter on-site assessment burden, making compliance materially faster and less expensive to maintain year over year.
What is the Integrity360 PCI Compliance Solution Assessment?
The Integrity360 and Reflectiz PCI Compliance Solution Assessment is an independent expert evaluation covering gap analysis against requirements 6.4.3 and 11.6.1, script inventory completeness review, approval workflow evaluation, audit evidence readiness scoring, and recommendations mapped to QSA examination procedures. It is available as a free gated download.
Can I try Reflectiz before committing?
Yes. Reflectiz offers a 30-day free trial. Organizations can provide their payment page URLs and receive a full script inventory, unauthorized change alerts, and compliance gap assessment – with no installation required and no code changes.
Does Reflectiz replace my QSA?
No. Reflectiz automates the evidence collection, script inventory management, and change detection workflows that QSAs examine – but it does not perform the assessment itself. It is designed to make QSA assessments faster, cheaper, and more predictable by ensuring compliance posture is continuously maintained rather than assembled under deadline pressure.
Does Reflectiz work with hosted payment pages and iFrame-based checkouts?
Yes. Reflectiz monitors the entire rendered payment page context, including iFrame content from hosted payment providers. This is particularly important for SAQ A merchants, whose eligibility depends on demonstrating that the parent page loading the iFrame is itself free from unauthorized scripts.
