01
Discover the observed script surface.
Identify first-party and third-party resources, providers, dependencies, browser capabilities, and network destinations captured during monitored payment-page activity.
BROWSER-SIDE PAYMENT PAGE SECURITY
Protect the browser side of configured payment pages.
Discover the scripts that reach checkout, understand their browser behavior, enforce deliberate boundaries, and retain technical evidence that can support reviews of PCI DSS Requirements 6.4.3 and 11.6.1.
A CONTINUOUS CONTROL LOOP
Know what runs. Control what changes. Document what happened.
SiteWall turns the browser-side portion of payment-page script governance into a live, traceable workflow. It supports specific payment-page controls, not the full PCI DSS standard.
02
Authorize with context.
Review why each script is present, define allowed behavior, and keep decisions connected to the resource they govern.
03
Monitor and preserve evidence.
Surface unexpected behavior or change, investigate it with session context, and retain a reviewable record for security and compliance teams.
RUNTIME DISCOVERY
See the payment page your customer actually receives.
Tags, payment services, fraud tools, analytics, and vendor dependencies can change after deployment. SiteWall observes the delivered browser experience so your inventory reflects live behavior, not only source code or tag-manager configuration.
PRECISE ENFORCEMENT
Give each payment-page resource the access it needs, and no more.
Move from blanket trust to explicit, understandable policy. Establish a global baseline, inherit approved defaults, and add provider or resource-level boundaries only where the payment flow requires them.
Zero-trust defaults
Set newly discovered resources to require explicit review before they are trusted.
Network boundaries
Limit where a script may send requests, including approved regions and domain patterns.
Granular browser permissions
Control access to storage, DOM content, network APIs, device features, and other browser capabilities.
CAPABILITY-LEVEL CHECKOUT CONTROL
Reduce what each payment-page resource can reach in the browser.
Use observed runtime behavior as review context, then deliberately grant only the supported browser capabilities required by the payment flow. Apply narrower boundaries to individual providers or resources instead of giving every checkout script the same broad access.
Usage-informed starting point
Compare observed capability use with the resource's documented checkout purpose before selecting a permission baseline.
Granular resource boundaries
Control supported access to storage, DOM content, network APIs, device features, and other browser capabilities at the level the payment flow requires.
Deliberate staged enforcement
Review and test stricter permission states before applying them to production checkout behavior, with a recovery path for essential functionality.
BROWSER-SIDE SUPPORT FOR PCI DSS
Support specific payment-page controls with browser evidence.
SiteWall focuses on client-side script governance and change monitoring relevant to PCI DSS v4.0.1 Requirements 6.4.3 and 11.6.1.
6.4.3 / INVENTORY
Maintain a current script register
Continuously identify scripts present on payment pages and retain the provider, resource, first-seen, last-seen, and behavior context needed for review.
6.4.3 / AUTHORIZATION
Record authorization and justification
Keep the approval state and business purpose associated with each payment-page script, creating a clearer path from technical asset to accountable decision.
11.6.1 / CHANGE
Detect unexpected page changes
Observe script and page behavior for unauthorized or unexplained change and route meaningful findings into an investigation workflow.
MONITORING / EVIDENCE
Keep reviewable technical context
Keep findings, current decisions, latest dispositions, audit observations, and supporting telemetry available so teams can explain what was observed and how it was handled.
FROM CONTROL TO EVIDENCE
Give reviewers a browser-side record, not a reconstruction project.
For the controls SiteWall supports, review readiness depends on more than a script list. SiteWall connects relevant requirements, browser findings, actions, and technical evidence for export.
Browser-side status by requirement
See SiteWall's coverage in the context of the relevant PCI DSS payment-page requirement.
Actions and technical evidence
Keep remediation steps, authorization records, browser monitoring context, and technical findings attached to the relevant requirement.
Exportable browser-side reporting
Generate a portable report package for internal review, assessment preparation, and stakeholder follow-up.
ONE OPERATIONAL WORKFLOW
From browser observation to compliance review.
A shared browser-side workflow helps security, engineering, and compliance teams move without losing context between tools or handoffs.
| Stage | What the team does | What remains |
|---|---|---|
| Discover | Observe supported payment-page resources and the dependencies captured as they load in the browser. | Browser-observed inventory |
| Review | Confirm ownership, purpose, expected capabilities, and destinations. | Decision context |
| Control | Apply inherited or resource-specific browser and network boundaries. | Explicit policy |
| Investigate | Connect an unexpected change to resource, session, alert, and issue context. | Traceable response |
| Prove | Map browser-side records to the supported requirements and generate a review-ready report package. | Browser evidence package |

PAYMENT PAGE SECURITY FAQ
Clear answers for security and compliance teams.
What SiteWall covers, how it supports PCI DSS payment-page work, and where organizational responsibility remains.
What does payment page security include?
Payment page security covers the scripts, tags, frames, network requests, and browser capabilities involved when a customer enters or submits payment data.
How SiteWall helps:SiteWall observes the delivered payment-page environment and connects resources to providers, dependencies, behavior, and destinations.
How does SiteWall support PCI DSS Requirement 6.4.3?
Requirement 6.4.3 includes requirements to manage and authorize payment-page scripts, maintain an inventory, and document why each script is necessary.
How SiteWall helps:SiteWall maintains a browser-observed script inventory and keeps authorization, business justification, and resource context together for review.
How does SiteWall support PCI DSS Requirement 11.6.1?
Requirement 11.6.1 addresses change- and tamper-detection mechanisms for payment pages and related HTTP headers as received by the consumer browser.
How SiteWall helps:SiteWall observes supported client-side behavior during deployed monitoring and configured audits, surfaces unexpected changes, and keeps the finding, affected context, and latest disposition available.
Can SiteWall identify scripts loaded indirectly by an approved vendor?
Yes. A trusted payment, analytics, or tag-management script can introduce additional resources that are not obvious in source code or the original configuration.
How SiteWall helps:SiteWall traces the delivered dependency chain so teams can review both the initiating provider and the resources it loads.
What happens when a payment-page script behaves unexpectedly?
An unexpected destination, capability, or resource change needs enough context for a reviewer to distinguish a legitimate update from an incident.
How SiteWall helps:SiteWall connects the finding to the resource, provider, observed behavior, available session context, current policy decision, and latest disposition.
Can teams introduce payment-page controls without blocking everything at once?
A staged rollout helps teams establish the expected payment flow before applying stricter boundaries to production behavior.
How SiteWall helps:SiteWall supports inherited baselines and targeted provider or resource policies, allowing controls to become more specific as the observed inventory is reviewed.
Does SiteWall make a website PCI DSS compliant?
No single product can determine an organization's PCI DSS compliance. Compliance depends on scope, implementation, operating processes, and assessor judgment.
How SiteWall helps:SiteWall provides technical monitoring, policy, workflow, and evidence capabilities that can support your payment-page controls and assessment preparation.
Can SiteWall work with existing payment, tag-management, and security tools?
Yes. Payment pages often depend on existing processors, fraud tooling, tag managers, observability systems, and incident workflows.
How SiteWall helps:SiteWall adds browser-side visibility and control while preserving the operational context teams need to work with their existing stack.
What evidence can teams export?
Useful browser-side evidence includes the observed script inventory, current approval and justification records, status for supported controls, findings, audit observations, monitoring context, and latest dispositions.
How SiteWall helps:SiteWall packages the relevant requirement context and browser-side technical record into an exportable report for review and follow-up.
