Jscrambler vs Content Delivery Networks

What is Jscrambler?

Purpose-Built for Securing the Client-Side.

Jscrambler is the only platform designed from the ground up to protect web applications where traditional tools fall short—on the client side. It delivers advanced runtime monitoring, code protection, and PCI DSS v4 compliance workflows that CDNs and one-size-fits-all vendors simply don’t offer.

Three reasons customers choose Jscrambler vs a Content Delivery Network (CDN)

Best-in-Class Client-Side Protection

Unlike CDNs that treat client-side security as a secondary feature, Jscrambler offers capabilities, including code obfuscation, skimming detection, form fencing, behavior-based blocking, and deep compliance expertise, all tailored to modern JavaScript threats.

Precision Over Consolidation

Generic security bundles often lead to diluted protection. Jscrambler is laser-focused on the browser layer, ensuring your PCI DSS v4 requirements are met with clarity, speed, and dedicated workflows built with expert input.

Flexibility and Top-Notch Performance

Jscrambler’s hybrid architecture provides instant visibility through agentless monitoring and deep protection via agent injection, ensuring speed and security without the complexity or performance tradeoffs of bundled tools.

“CDNs offer dozens of products, but we prefer to rely on specific partners to do a specific job and be the best at what they do. We weren’t looking for vendor consolidation—we were looking for depth and focus. That’s why we chose Jscrambler. They’re not just another checkbox; they’re purpose-built for securing the client side and helping us meet PCI DSS v4 requirements with confidence.”

What makes Jscrambler different?

Simplified Compliance, No Guesswork

Jscrambler automates the script inventory and approval process required by PCI DSS v4 with Delegated Compliance. You don’t have to manually approve each vendor or evaluate every new third-party service—our team handles it for you.

Streamlined Script Management at Scale

Jscrambler groups scripts by vendor service, instead of individual scripts, to reduce the workload and help approve behaviors faster. This dramatically reduces manual overhead, ensures accuracy, and blocks risky behavior without breaking functionality.

Hybrid Architecture, Real-Time Protection

Start with agentless monitoring for instant visibility, then enable the agent for advanced protection and compliance. Jscrambler adapts to your transaction volumes and scales with your needs, delivering performance and precision that CDNs can’t match.

JavaScript Security Expertise

Jscrambler's years of expertise in JavaScript security sets itself apart, providing customers with the guidance and support necessary to effectively protect first-party JavaScript, and third-party tags, in a cost-effective manner that enables compliance while building trust.
