A Strong Alternative to Feroot
Stop eSkimming attacks and script-based data leaks at runtime
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.

Why Teams Look Beyond Feroot
Security and compliance leaders evaluating Reflectiz often run into the same issues:
Visibility without full control. Feroot helps you see scripts, cookies, and front end risks, but it does not continuously control what those scripts can read, write, or send in real time on every page.
Alert and approval fatigue. Risk scores and change alerts still rely on your team to decide what to do, open tickets, and prove that nothing slipped through before the next assessment.
PCI DSS 4.0.1 expects outcomes, not only dashboards. Requirements 6.4.3 and 11.6.1 call for preventing unauthorized scripts and detecting tampering across the payment flow, not just listing assets and issues.
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 card data, you need runtime control over script behavior, not only another layer of monitoring.

How Source Defense is Different
Real time behavior based protectionSource Defense runs in the browser and controls script behavior as it happens so sensitive data never leaves the page in the clear.
- Isolates third and fourth party scripts from payment and account fields
- Redacts keystrokes so keyloggers and skimmers see only masked values
- Blocks unauthorized or unknown scripts from executing at all
- Enforces least privilege policies across the entire payment flow
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.
Less manual work, more automation
Feroot helps you identify what needs attention. Source Defense goes further and automates protection and reporting so your teams are not buried in approvals and tickets.- Policy driven protection instead of one off decisions
- Automatic logging and evidence generation for PCI DSS reviews
- Minimal operational effort once policies are tuned
Your teams spend more time improving security and less time chasing script changes.
Purpose built for PCI DSS 4.0.1
Source Defense was designed to address the client side requirements in PCI DSS 4.0.1 and the eSkimming problem behind them. You get:
- A complete inventory of first, third, and fourth party scripts across payment flows
- Business justification, approvals, and risk ratings for each script
- Continuous change and tamper detection on scripts and security impacting headers
- Evidence grade reports mapped directly to 6.4.3 and 11.6.1 for QSAs and internal audit
This turns PCI DSS 4.0.1 from a manual scripting project into an ongoing, automated control.
Source Defense vs Feroot at a glance
| Capability / Outcome | Feroot | Source Defense |
|---|---|---|
| Primary focus | Discovering client side risks, assets, and misconfigurations | Behavior based runtime protection and PCI DSS evidence |
| Control over scripts | Shows which scripts and cookies are present and risky | Controls what scripts can read, write, and send in real time |
| PCI DSS 4.0.1 support | Helps with asset discovery and compliance reporting | Evidence grade reporting plus real time enforcement for 6.4.3 and 11.6.1 |
| Operational impact | Ongoing alert review, triage, and approvals | Policy driven automation with minimal monthly effort |
| Data coverage | Strong focus on card payment flows and web assets | Card data, credentials, PII, and other sensitive web data |
| Outcome | Better visibility into client side risk and compliance gaps | Reduced eSkimming risk and faster, more defensible PCI DSS 4.0.1 compliance |
Protection beyond card data
Cardholder data is only part of the exposure on modern sites. Source Defense policies also monitor and control script behaviors that touch:
- Customer credentials and account data
- PII and contact information in web forms
- Health, financial, and other regulated data collected in the browser
You support PCI DSS, privacy requirements, and sector specific regulations with a single client side control.
What To Expect In The First 30 Days
Source Defense uses a defined onboarding process that moves from discovery to full protection in less than a month.
You can expect:
- Automatic discovery and scoping of all scripts across your payment flows
- A custom PCI dashboard with live findings
- Recommended behavioral policies for each script
- Quick deployment and validation
- QSA ready reporting for 6.4.3 and 11.6.1
About Source Defense
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.
