Source Defense gives you behavior based, real time protection across your payment flows, not just visibility into scripts and headers. Reflectiz focuses on monitoring and approvals. Source Defense isolates risky scripts, blocks data theft in the browser, and delivers evidence grade reporting for PCI DSS 4.0.1.
See behavior based protection in a live demo and get instant insight into script behavior, risk scoring, and PCI DSS compliance gaps.
Security and compliance leaders evaluating Reflectiz often run into the same issues:
Visibility without full control. Monitoring shows you which scripts are present, but it does not actively control what those scripts can read, write, or send in real time.
Alert and approval fatigue. Smart approvals still leave your team reviewing script changes, chasing risk scores, and closing tickets before the next audit.
PCI DSS 4.0.1 expects more than a dashboard. Requirements 6.4.3 and 11.6.1 call for preventing unauthorized scripts and detecting tampering across the payment flow, not just listing scripts and headers.
Manual work that does not scale. Large commerce sites struggle to keep up with constantly changing third and fourth party scripts when inventories and approvals are heavily manual.
If your goal is to cut eSkimming risk, simplify PCI DSS 4.0.1, and protect more than just card data, you need runtime control over script behavior, not another monitoring view.

Real time behavior based protection
Source Defense runs in the browser and controls script behavior as it happens.
Instead of only seeing that a risky script exists, you decide exactly what it is allowed to do and Source Defense applies that policy in real time.
Reflectiz helps you see and review activity. Source Defense goes further and automates protection and reporting so your teams are not buried in approvals and tickets.
Your teams spend more time improving security and less time chasing script changes.
Source Defense was designed to address the client side requirements in PCI DSS 4.0.1 and the eSkimming problem behind them. You get:
This turns PCI DSS 4.0.1 from a manual scripting project into an ongoing, automated control.
| Capability / Outcome | Reflectiz | Source Defense |
|---|---|---|
| Primary focus | Monitoring and approvals for scripts and headers | Behavior based runtime protection in the browser |
| Control over scripts | Shows which scripts are present and risky | Controls what scripts can read, write, and send in real time |
| PCI DSS 4.0.1 support | Helps with inventory and reporting | Evidence grade reporting plus real time enforcement for 6.4.3 and 11.6.1 |
| Operational impact | Ongoing alert review and approvals | Policy driven automation with minimal monthly effort |
| Data coverage | Mainly card payment flows | Card data, credentials, PII, and other sensitive web data |
| Outcome | Improved visibility into client side risk | Reduced eSkimming risk and faster, more defensible PCI DSS 4.0.1 compliance |
Cardholder data is only part of the exposure on modern sites. Source Defense policies also monitor and control script behaviors that touch:
Source Defense uses a defined onboarding process that moves from discovery to full protection in less than a month.
You can expect:
As a PCI Participating Organization and the pioneer in eSkimming security, Source Defense played a role in the development of new requirements for web security found in PCI DSS 4.0.
We’ve helped thousands of the world’s leading brands address these issues. We’ve also been educating merchants, QSAs, PSPs, eCommerce Platform providers and virtually every stakeholder in PCI compliance on the vulnerabilities in modern website design that make eSkimming attacks possible. We’ve made it our misison to provide guidance around ambiguity in the standard; advise on the pros and cons of approaches provided by the council and we recently launched a free assessment, monitoring and management solution for both merchants and their QSAs.
