CLIENT-SIDE SECURITY SUITE

JSIR for payment page security

JSIR helps teams address PCI DSS 6.4.3 and 11.6.1 with automated script inventory, owner mapping, Dynamic SRI integrity monitoring, payment page change detection from the end-user browser, and evidence for QSA review.

PCI DSS 6.4.3
PCI DSS 11.6.1
Dynamic SRI
Change Detection

Integration without heavy rework

Real-session monitoring

Webhooks to SOC/SIEM

Script inventory

Automated catalog of DOM scripts and third-party sources, including GTM and widgets, with owners, justification, and review status for 6.4.3.

Dynamic SRI and signatures

Dynamic SRI support: hash and digital signature generation for static resources to reduce substitution risk and verify delivery integrity.

Change detection for 11.6.1

Comparison of HTML, JavaScript, and HTTP headers from the end-user browser against the approved baseline, with deviations recorded and notifications sent.

Audit reporting

Exports for inventory, change logs, and check results. JSIR prepares practical evidence for QSA and internal audit reviews.

Client-side threat coverage

Web skimming, formjacking, and third-party script injections are captured as the customer's browser renders the page.

Low operational overhead

Sensors and crawlers are optimized for low conversion impact and predictable cost of ownership.

SOC/SIEM integration

Ready webhooks and SIEM log export can route events into SOC workflows and keep investigation artifacts reproducible.

Payment page changes in PCI DSS 4.0.1

PCI DSS 4.0.1 keeps the focus on payment page security and makes client-side script governance and change detection operationally important for e-commerce environments.

6.4.3 Payment page script control

Requirement 6.4.3 expects organizations to manage scripts loaded and executed on payment pages, including authorization, business justification, and integrity controls.

11.6.1 Payment page change detection and response

Requirement 11.6.1 emphasizes change detection and response for payment pages, with notification to authorized personnel when unauthorized modifications are detected.

These changes reinforce continuous risk management for payment data security. Preparing the processes, controls, and evidence for 6.4.3 and 11.6.1 helps teams avoid late audit findings.
