Jscrambler Client-Side Protection and Compliance Platform
SMBs and mid-market companies handling payment data on their own websites need Jscrambler Client-Side Protection and Compliance Platform to stop third-party script compromise and data exfiltration at runtime, not just in code review. PCI DSS v4 compliance support with automated payment page blocking and polymorphic obfuscation that self-heals against tampering gives you control over client-side risk that traditional WAFs simply cannot reach. Skip this if your JavaScript is minimal, your third-party vendor footprint is small, or you're building a pure API-first product; the ROI case weakens without exposure at scale.
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.
