CST VerdictBased on our analysis of core features, integrations, company size fit, deployment model, here is our conclusion:
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.
