Jscrambler Webpage Integrity vs Source Defense Platform: Side-by-Side Comparison (2026)

Jscrambler Webpage Integrity

Mid-market and enterprise teams managing payment flows, form submissions, or user authentication through third-party scripts need Jscrambler Webpage Integrity to stop data exfiltration before it leaves the browser. The platform's real-time inventory of script behavior paired with granular policy enforcement gives you control where you actually lose data, and PCI DSS v4 6.4.3 and 11.6.1 compliance modules mean your audit story is already built. Skip this if your third-party ecosystem is minimal or your team lacks the discipline to maintain script policies; the tool demands governance rigor or it becomes noise.

Source Defense Platform

Mid-market and enterprise teams managing high-risk web applications should pick Source Defense Platform if third-party JavaScript is your actual attack surface. The platform's real-time sandboxing and AI-driven detection of formjacking and keylogging attacks addresses a gap most ASPMs ignore, and its support for PCI DSS and GDPR compliance violations gives you the audit trail you need. Skip this if your threat model centers on server-side vulnerabilities or you need deep integration with your existing WAF; Source Defense is client-side focused, which is its strength and its limitation.
